Design and principle of operation

Diesel fuel is pumped to the burner device from the storage tank. The pump is fitted with a recirculation line to release any leftover fuel oil from the burner, ensuring optimal fuel pressure. Before the nozzle is installed, the fuel is purified using a two-step process: first, the coarse filter removes mechanical impurities, and then the fine filter filters the fuel before it reaches the burner by heating it to the proper operating temperature.

Following its entry into the nozzle, the diesel ignites from the igniter after mixing with air. The torch then burns in the combustion chamber, where its shape is controlled by unique blades that produce an airflow that swirls the atomized fuel particles. Fuel-air mixture is ignited by electrodes placed in front of the nozzle. Safety devices have complete control over the process.

A fan forces air in, and pressure sensors control how loud it is. The configuration of the furnace chamber guarantees full combustion of the liquid energy carrier at operating temperatures. A smoke pump, whose operation is also automated by pressure drops in the gas path, expels flue gases through the gas path. Air dampers and the smoke evacuator guide apparatus control it.

Varieties of diesel burners

Numerous diesel burner types are available for use in domestic boiler construction; the type chosen will depend on the fuel’s chemical makeup and the type of steam generator (water-water or steam-water).

Liquid fuel burners that are single-stage, multistage, and modulated are categorized based on their capacity. The first are the most basic and least expensive, with only one fully functional mode.

Two-stage multistage devices that run at 50% or full capacity are the most widely used. The degree of automation enables mode switching while the boiler is operating. The burner goes into low mode when heat consumption drops, which evens out temperature variations in the primary heating network. Boilers that don’t produce more than 80 kW of heat can perform this kind of operation.

Modulated devices can smoothly regulate the temperature mode and have a wide range of power variation. They are utilized in high-power steam generators because of their intricate design and high precision.

The modular burners’ set of automatics consists of:

• Sensor for flame presence and combustion control;
• control module of the fan air supply system;
• flame chamber cleaning system;
• temperature and pressure sensors on the primary and secondary coolant circuits;
• pressure sensors in the fuel network;
• safety devices, shut-off valves and alarm system.

The cut-off valve receives a signal from the sensors in the event of an emergency, stopping the fuel supply to the boiler and returning it to the tank via the circulation line. To alert the operating staff, an emergency alarm is also activated simultaneously. These systems have a backup power source because the diesel burner and the boiler unit function as a whole only when there is a steady supply of electricity available.

Selection criteria

Because the boiler’s liquid fuel combustion processes are fully automated, there is energy available nationwide, and starting the boiler room on solar oil doesn’t require any special permissions or approvals, diesel burners are widely used in boilers. As a result, there are too many of these devices on the market, making the decision difficult.

The following factors are crucial when choosing a diesel burner for the boiler:

1. Availability and type of fuel pump for the burner, it may not be suitable for certain fuels, e.g. viscous fuel oil.
