The Industrial Solid Propellant Copper Retra-4m Is 2000 Kw Capacity: 4.15 Cubic Meter (M3)

we are engaged in exporting and supplying of The industrial solid propellant copper Retra-4M is 2000 kW in Kiev, Kyyiv, Ukraine. Heating boilers with a maximum water temperature of 90 A C and operating pressure up to 0.2 MPa, with microprocessor control of the flow temperature regulated forced air flow and automated feeding fuel into the combustion chamber (translated to manual fuel loading mode, if necessary) - intended for heating the individual residential buildings and constructions of household purpose, equipped with heating systems with forced (closed heating system under pressure) or natural (open heating system) the circulation of coolant.

Principle of operation
Boilers "retro-4M" can operate in two modes - in manual and automatic fuel loading.
In the first mode of operation, fuel loading boiler (firewood, charcoal, briquettes, etc.) occurs through the charging port. The process of effective combustion in the furnace is carried out through an intensive air supply for the camera's perimeter. This forms an "air cocoon" around the fuel. The gas which is not burned in the furnace due to the lack of air, burns by supplying secondary air. This ensures high efficiency reaching 93%.
In the second mode, the fuel loading is done automatically from the hopper auger screw (driven by a gear motor) to the pellet burner.
