The PEL boiler is designed for heating residential and industrial premises, hot water supply systems, wood drying chambers equipped with a continuous heating water heating system with forced circulation and other technological purposes.
The PEL model is a solid fuel boiler with mechanized combustion of bulk fuel, on a retort with a lower fuel supply. Fuel through the retort is pushed by a screw onto a fixed grate. Primary air is supplied under the grill through openings located on the side surfaces of the grates. The grill is cooled by primary air. Secondary air is supplied through a series of holes located above the top of the cone-shaped slide of fuel. To achieve the correct flow ratio, the supply of primary and secondary air is separately regulated.
To prevent sintering of fuel with high ash content and low melting characteristics of the ash (ash melting temperature below 1100 ° C), the boiler design provides for periodic mixing of the fuel layer, with the drive from the boiler controller turned on.
Bulk fuel are: wood waste — granular sawdust and shavings, granulated peat milled; granular agricultural waste — sunflower and buckwheat husks. Granular fuel fraction 12x100 mm.
The design of the boiler provides for the automatic removal of ash and unburned residues beyond the boiler furnace volume into separate ash containers. Ash conveyors have independent separate drives, with switching on from the boiler controller.
The boiler is equipped with an automatic fuel ignition system, which simplifies operation and allows you to operate a cascade of several boilers — in automatic mode. Exhaust flue gases from the furnace passing through a two-way tube bundle and a chimney adapter give heat to the coolant.
The boiler is made of plate steel, insulated with basalt insulation and coated with sheet metal with a polymer coating. Automation of the boiler provides optimal conditions for the combustion of fuel, modulation of power within 20-100%, emergency and fire alarms.
