How to calculate pellet consumption?
Calculating the flow of pellets per 1 kW or 1 m2 is theoretically not difficult given that the fuel is supplied in bulk or packed in bags. Since the supply is always in kilograms and the heat of fuel combustion is also measured in kW per kilogram of weight, there is no need to convert the weight units into volume.
High-quality granules have exceptional heat-intensive properties; burning 1 kg of such fuel releases nearly 5 kW of thermal energy. As a result, burning roughly 200 grams of pellets is needed to produce 1 kW of heat for heating. Given that each 1 m2 of area requires 100 W of heat, calculating the average granule consumption per unit area is not too hard. There is one crucial requirement: the ceiling heights must not exceed 2.8–3 meters. It would appear that 20 grams of granules will produce 100 watts of heat. This is just basic math.
But it was not there. The numbers presented above are correct if the pellet boiler has absolute efficiency – 100% efficiency, and this does not happen in real life. In fact, the efficiency of such heat generators, although higher than that of solid fuel boilers, but still only 85%. This means that after the combustion of 1 kg of granules in the furnace of the unit, not 5 kW of energy will be obtained, but 5 x 0.85 = 4.25 kW. And vice versa, to release 1 kW of heat in pellet boilers, 1/4 is spent.25 = 0.235 kg or 235 grams of fuel. This is the first nuance.
The second nuance is that, in the event that the outside temperature drops to its lowest point for five days in a row, 100 watts of heat per square meter of space is needed. The average cost of heat energy is halved during the heating season. This indicates that there is only 50 watts of specific heat transfer per unit area. Calculating the amount of pellets that a pellet boiler can produce in an hour at a rate of 1 m2 will yield an inaccurate and uncomfortable result. Figuring out how much weight of granules burns each day will be more accurate.
Watts is a unit of power that is dated to one hour, so you will need 50 W x 24 hours, or 1200 W or 1.2 kW, per day for each square of the room. You will need to burn this much pellet each day in order to achieve this goal:
0.28 kg or 280 grams is equal to 1.2 kW / 4.25 kW/kg.
Once we have the precise fuel consumption, we can finally obtain the numbers that are needed for financial computations. For instance, we can find the average number of granules used daily and monthly in a 100 m2 house for the season:
- per day – 0.28 x 100 = 28 kg;
- per month – 28 x 30 = 840 kg.
It turns out that 8.4 kg of fuel are needed each month to heat 1 m2 of the building. At the same time, 550 kg of pellet leaves—which is decreased to the quadrature of 5.5 kg/m2—are needed to heat a 100 m2 well-insulated house in the middle lane, according to user reviews posted on a number of forums. This indicates that the monthly pellet consumption in a boiler of 840 kg with a 100 m2 building is considerably larger and appropriate for poorly insulated homes.
To provide a summary of some findings in the form of calculations for different areas’ homes. We were able to ascertain the following monthly pellet heating costs for a private residence:
- 100 m2 – 840 kg for weak insulation, 550 kg for good thermal insulation;
- 150 m2 – 1260 kg and 825 kg, respectively;
- 200 m2 – 1680 kg and 1100 kg under the same conditions.
As a point of reference. The controller in many boiler plants has a feature that lets you see the granules in kilograms on the display for a predetermined amount of time.
You must take into account several important factors when figuring out how much heating flow consumption your home will require. First, evaluate the size and quality of the insulation in your living area. The temperature and comfort level you want to attain should then be taken into consideration. Next, investigate any additional heat loss through windows, doors, and walls, as well as the effectiveness of your heating system. You can efficiently determine how much energy is required to keep your home warm by accounting for these factors. This procedure saves you money and lessens your influence on the environment by assisting you in making educated decisions about heating systems, energy use, and insulation upgrades.
Medium -quality pellets
The so-called elite, a measure of the heat-intensive capacity found in premium granules, was employed in the computations that were presented. They are made from the leftovers of high-quality wood and almost entirely free of unnecessary inclusions like woody cortex. Although different impurities raise fuel ash and lower its heat of combustion in the interim, the cost per ton of these wood pellets is significantly lower than elite. Many homeowners attempt to make their pellet heating more cost-effective by lowering the expense.
Apart from premium fuel pellets, less expensive granules are also produced using agricultural waste, typically straw, and have a slightly deeper color. Although they have a low ash content, their reduced heat-intensive ability of 4 kW/kg will ultimately effect the amount consumed. In this instance, the consumption for a 100 m2 house would be 35 kg per day and up to 1050 kg per month. Granules made from raps straw are an exception; their heat of combustion is comparable to that of birch or coniferous pellets.
Other granules are made from a range of waste materials from woodworking businesses. They are full of various impurities, such as bark, which can cause malfunctions in modern pellet boilers, including malfunctions in the work itself. Naturally, there is always an increase in fuel consumption when the equipment operates erratically. They are particularly frequently mischievous due to low-quality heat generator granules with retorted burners in the shape of bowls. There, the air passage is situated, and the screw supplies fuel to the lower portion of the "bowl." The reduction in combustion intensity is a result of the soot they acquire.
So that such situations do not arise and the efficiency of the boiler does not decrease, it is advisable to choose a fuel with low ash and in no case is a wet. Otherwise, problems with a screw feed will begin due to the fact that wet granules scatter and turn into a dusty mechanism. You can use cheaper fuel for heating a house with pellets when the boiler is equipped with a torch -type burner. Then the ash covers the walls of the furnace and falls down without getting back into the burner. The only condition is to serve and clean the burning camera and the elements of the burner will have to be more often, as it is contaminated.
One of the most important steps in making sure your home’s heating system is both efficient and comfortable is calculating the flow consumption for heating. You can choose the right size and capacity for your heating system by being aware of the variables that affect heat demand and loss.
Your home’s insulation level is one of the most important things to take into account. By minimizing heat loss, proper insulation lowers the energy required to keep interior temperatures comfortable. You can estimate heat loss and choose the right size heating system by evaluating the insulation in your walls, floors, and ceilings.
Your heating requirements are also greatly influenced by the climate in which you reside. In order to maintain comfortable indoor temperatures, warmer climates might require less heating, while colder climates might require more. You can compute a more precise estimate of your heating flow consumption by accounting for the average outdoor temperatures and the local climate.
When calculating flow consumption, it’s also critical to take your heating system’s efficiency into account. Because they use less energy to produce the same amount of warmth as older models, modern heating systems are designed to be more energy-efficient than those older models. You can cut your heating expenses and overall energy consumption by selecting a high-efficiency heating system.
In conclusion, determining the flow consumption for heating entails taking a number of variables into account, such as the climate, the amount of insulation in your home, and the effectiveness of your heating system. You can make sure that your house stays cozy and energy-efficient during the heating season by considering these variables.
