WATER-HEATING SOLID-PROPELLANT BOILER Russian patent published in 2009 - IPC F24B1/183 F24H1/12 

FIELD: heat engineering.

SUBSTANCE: invention relates to energetics, particularly to devices for heating of individual dwelling and supply by domestic hot water in places, where are absence modern heat sources and is excess wastes of combustible-lubricating materials. Water heating solid-propellant boiler contains body with steel double-layer walls, forming water jacket, at least one convection air- gaseous pass, located between water heating pipes and connected to gas-collecting manifold, particulate bin, locked on combustion chamber with fire grate, under which there are located facility of delivery of primary air and ash bin, bottom pipeline of cold water supply and top pipeline of hot water drainage. In inner space of body double-layer walls form additional water jacket in the form of frontally located top and bottom flanges, where on bottom flange of water jacket it is installed heat-reflecting barrier made of refractory material, forming with top flange upward slotted nozzle, located in combustion zone and by its butts thrusting into external opposite walls of body, where opposite to each other it is implemented at least by one "reach-through" hole for delivery of secondary air into slotted nozzle into combustion zone. Water heating pipes are flowing connected to water jacket of external opposite walls of body. Gas-collecting collector is located in bottom part of combustion chamber in external wall of body.

EFFECT: expansion of heating area, creation of optimal conditions for circulation of water at its heating in boiler, effectiveness increase of fuel burning and increasing of duration of its burning from loading till loading, simplification of attendance and operation of boiler.
