Solid fuel boiler (definition)

Solid fuel boiler is a heating device that uses various types of solid fuel as fuel, such as firewood, coal, briquettes, peat and pellets. The main function of a solid fuel boiler is to convert the combustion energy of solid fuel into thermal energy for space heating and water heating.

Hydraulic piping of the boiler (boiler circuit) must include security group, ensuring normal operation.

Structurally, a solid fuel boiler includes:

1. Combustion chamber - the space where solid fuel combustion occurs.
2. Grate - the surface on which fuel is placed and through which ash and residues are removed.
3. Heat exchanger - a device that transfers heat from combustion products to the coolant.
4. Chimney — system for removing flue gases.

A key feature of a solid fuel boiler is the ability to control the combustion process by regulating the air supply using a microcontroller PLUM ECOMAX. This includes:

• Mechanical air supply — manual adjustment of air dampers or valves.
• Automatic air supply — use of a fan or air blower controlled by an automation system.
• Primary and secondary air control — primary air is supplied directly to the fuel to maintain combustion, and secondary air is supplied to the upper layers of the combustion chamber for afterburning of gases.

These methods make it possible to effectively control the combustion intensity and, consequently, the power of the boiler, which improves its efficiency and reduces emissions of harmful substances. Solid fuel boilers are popular in areas with accessible solid fuel and can be used as primary or backup heating equipment.
