Retra-4M Combi boiler, 80 kW with flare burner
Overview
A flare burner is installed in the lower hatch of the boiler, into which fuel is mechanically supplied from the hopper. Fuel combustion takes place in the lower chamber. This automatic loading mode is designed for burning pellets (including agro-pellets, in a lined burner). The pellet burner torch is directed at the rear wall of the boiler furnace with lining. The process of automatic ignition, burning and cleaning of the burner is controlled by a multifunctional control unit. Mechanized fuel supply, Hopper and automation are supplied complete with a flare burner.
Boilers are designed to work in central water heating systems with forced (closed pressure heating system) or natural (open heating system) circulation of heat carrier for heat and hot water supply of residential buildings, dachas, industrial and warehouse premises, retail facilities, social and administrative buildings.
The Boilers are designed to operate in systems with an operating pressure of no more than 0.2 MPA (on request - 0.6 MPA) and a water temperature at the boiler outlet of no more than +95 °C.
