The principle of operation of automatic coal boilers

Comprehending the mechanism and working principle of contemporary automated boilers is crucial, as it will aid in selecting the appropriate model. For the coal boiler and its supporting heating system to operate independently for an extended period of time, the following procedures need to be automated in a safe and cost-effective manner:

  • loading of portions of coal or other fuel;
  • Cleaning of ash from the combustion zone to the drive;
  • The air supply from the fan of the boost to the burner should be adjusted;
  • The temperature in different rooms corresponded to the given;
  • The warm floor will be heated as set;
  • Hot water is available at all points of analysis;
  • circulation pumps and mixing valves correctly direct the coolant and warm water.

The user function consists of selecting the coolant temperature or the temperature in each room, as well as the operating mode (priority or schedule). The processor interprets dynamic processes that are contingent upon various factors such as weather variations, water flow, fuel quantity and quality, and air flow. Because an automatic coal boiler’s complete set of options can be costly, only the most labor-intensive operations—fuel loading and bias in air—are frequently automated.

The fundamental working principle of the boiler remains unchanged: oxygen enters the burning coal through the blown, assisting in the burning process, and the spent gases exit through the chimney. The coolant in the container surrounding the burning coal is warmed by thermal energy, and the heated coolant travels through the pipes to the radiators. After providing heat, the liquid goes back to the boiler to reheat.

Option two for burning coal:

  1. Classical. Coal burns out, and pyrolysis gases go into the atmosphere.
  2. Pyrolysis. The diverting gases are saturated with oxygen and are burned, thereby increasing the efficiency of the boiler and increasing the burning time of one portion of coal at least twice, but the cost of pyrolysis models is also at least twice as high as.

The boiler is also conventionally constructed. When burning coal in a traditional firebox, the coal burns on grates, air is naturally supplied from below, the blower door is regulated by the level of the coal, and the chimney damper controls the diverted gases. Burning coal envelops the boiler’s body, a capacity that houses the coolant. In order to prevent smoke from escaping from a well-functioning boiler, a forced air supply system for gas and solid particles is installed above the traditional firebox when using the pyrolysis version.

There are numerous coal boilers on the market that have varying degrees of automation.

Fuel supply system

Fuel loading is the most time-consuming and messy task involved in operating coal boilers with automatic supplies. Now that this procedure has been automated, you can guarantee that the hopper will only be filled once every week. It will be more comfortable for everyone to live in the house during the whole heating season if you can automate the seasonal warehouse’s coal supply to the boiler bunker.

Two types of automatic coal supply system structures were received for coal boilers: screw and drum types.

On the side of the boiler is a bunker filled with coal for filling a pyrolysis (and frequently traditional) boiler. The box has a screw in the bottom that rotates thanks to an electric motor that is controlled by the computer when it is operating automatically or by a button when it is operating manually. The computer is set by the engine’s duration, which determines how much coal is loaded into the boiler. Boost is activated concurrently to regulate the combustion process.

With a bunker filling up to once a week and variations in rated power from 30% to 100%, the boiler with this kind of automation maintains a high efficiency while effectively practicing weather changes and setting user. Once a week, a high-quality coal hopper needs to be filled (with a fraction of 5 mm to 25 mm, depending on the model).

Coal bunkers are frequently positioned above boilers in traditional combustion boilers, and automatic coal loading is accomplished by means of a drum (rotating grate). A portion of the solid fuel is supplied to the furnace by him as he rotates around his own axis. Ash and slag burn and fall into the drive. In this instance, there are numerous unique design options for the automation of these boilers, and the fuel requirements are reduced.

Removing ash

After placing coal into the bunker, the second unpleasant process is clearing the drive’s ash and slag, as well as any scattered crust. It is ideal for both procedures to take place on the same cycle, which is once a week, if the boiler is not connected to a transporter with a seasonal fuel warehouse. Self-cleaning models still need maintenance, but only every four to six weeks.

Ash is one type of coal quality that directly affects how much ash is in the drive. Boilers for direct combustion can run on household waste and have low fuel quality requirements. However, the use of weapons will need to increase, and the specified qualities can produce coal with an ash content of less than 25% and a humidity below 30%.

Pyrolysis boilers require a specific size of coal fractions, ranging from 5 mm to 25 mm, in addition to reduced humidity up to 20% and ash less than 15%. If these specifications are not met, the unit’s qualities are diminished and its ash content rises. After sorting through the drive’s ash, some of the coal that hasn’t burned can be used again.

Boilers that use liquids for automatic ignition, ones that don’t require manual ash removal from the drive, and ones that have the ability to self-clean their burners are uncommon but can be added as extra features for very expensive boilers. relying, as opposed to pellet, on a self-cleaning system in coal models.

Reviews of household coal boilers with automatic supply

Advantages Flaws
A properly automated combustion process allows you to burn the coal almost three times slower than firewood or pellets. The cost of budget boilers with a set of protozoa options is close to the cost of coal boilers of long burning from leading manufacturers or completely equipped gas units of the highest price category.
Such boilers require a minimum of intervention on the part of a person, one loading of coal with the smallest bunkers is enough to work for 3-5 days, in the case of volumetric bunkers-up to 1-3 weeks or a whole heating season, if additional automatic fuel supply is carried out to the bunker From the external storage. Bunkers of automatic coal boilers are rarely hermetically insulated from the external environment, sometimes not even equipped with a lid. Therefore, for the volume of coal of the filled bunker, a persistent smell makes a persistent. It is preferably and a separate storage of fuel and a boiler house from a residential building. Smoke, coal dust, smell pollute the surrounding space.
The control and design of the boilers even with extremely advanced automation is intuitively understood, and the device of ordinary boilers differs little from the stove. All automatic coal boilers are exclusively energy -dependent, that is, for work they require connection to the mains.
Coal boilers are omnivorous, even pyrolysis, if necessary, can burn any solid fuel, but the efficiency and power in this case suffer significant losses (efficiency by 20%, power up to 20%-40%of the face value). Dependence on the quality of coal, for example, the fuel of a large fraction simply cannot be transported to the furnace chamber and blocks the supply system.
On the basis of an automatic coal boiler, you can create a fully autonomous heating system, especially in the presence of alternative sources of electricity.

What to look for when choosing

The primary operating features of automatic coal boilers, which are thought to be standard, are listed in the table below.

Parameter Classical Pyrolysis
Efficiency 78%-84% 85%- 95%
Bunker refueling Up to 5 days 4-7 days
Fuel moisture 20%-30% 7%-15%
Coal faction 25 mm – 50 mm 5 mm – 25 mm
Ash Up to 25% Up to 15%

The ratio of fuel consumed to thermal power produced by the boiler is called the utility coefficient, or efficiency; the higher the number, the better. Calculations for heating a specific room and the required amount of hot water consumed determine the boiler’s power; we will address the calculation principle in more detail later.

Once you’ve decided on the essential features, you should consider the extra features that will raise the unit’s cost and level of comfort:

  • The degree of automation of equipment (additional options from unloading ash to control from a mobile phone);
  • the material of the heat exchanger (cast iron is more durable, steel is cheaper, lighter and more maintained);
  • The volume of the combustion chamber. The more, the less often the fuel supply is turned on, which issues noise and consumes electricity;
  • the size and device of the chimney;
  • Fire safety.

The only remaining question is how much the boiler will cost. The desired set of properties is ready to fully supply the modern market.

Boilers that can burn a single fuel for up to seven days

In today’s world, where energy efficiency and environmental impact are significant concerns, coal automatic boilers offer an effective solution for heating private homes. These boilers efficiently burn coal, providing consistent heat throughout the house while minimizing fuel consumption. With automation features, they require minimal manual intervention, making them convenient for homeowners. Moreover, coal is a relatively inexpensive fuel source, offering cost savings over time. However, it"s crucial to consider the environmental implications of burning coal, as it contributes to air pollution and carbon emissions. Therefore, while coal automatic boilers offer effective heating solutions, it"s essential to balance their benefits with their environmental impact and explore alternative heating options for a sustainable future.

Calculation of the minimum required power

You will be able to tolerate any frosts with ease and always have enough warm water if the power calculation is done correctly. The minimal power required for a typical house with two brick walls and ceilings no higher than 2.7 meters is determined at a rate of 1 kW per 10 m 2 of heated space.

The computation is done independently for each room, according to technology, but in reality, the entire area is frequently divided by 10 and multiplied by 1 kW. Then, to increase the resulting power by 20%, the losses and computation errors are added.If the DHW contour is planned, an additional 20% of the reserve must be added.

For instance, when operating on a 150 m 2 area, the boiler’s standard power for heating and DHW can be (150×1)/10 = 15 kW for heating. However, a power source is required. A 3 kW supply is needed for unanticipated frosts, losses, and errors (15 kW x 0.2). For each hot water, 15 kW x 0.2 = 3 kW. In this instance, the boiler’s minimum required power should be at least 15 + 3 + 3 = 21 kW.

The boiler is underloaded with power, but there are still opportunities to use it more extensively in the future. A mistake resulting in a power outage guarantees discomfort loss and an unavoidable heating system modification.

This is essentially an estimate calculation; it is possible to use heat engineering for an accurate calculation or to recalculate the hot water consumption in accordance with the norms by relying on SNiP 2.04.01-85. However, you will still need to account for the margin of strength, and the model that you choose will not have a significant impact on this estimate. In more than 90% of cases, the above simple calculation applies to a private house up to 400 m 2.
