WATER BOILER Russian patent published in 2009 - IPC F24H1/00 

FIELD: heating.

SUBSTANCE: invention is designed for water heating and is to find application in boiler engineering. The proposed water boiler is composed of the following component parts: a fuel bin; a furnace equipped with a grate, a raking bar and a drive; convection tube bundle assemblies; a system for forced supply of air into the boiler furnace and supply of heat medium into the convection bundle assembly tubes. The grate is sloped off the fuel delivery bin. The raking bar is represented by a pendulum composed of a bar and two side pieces kinematically connected via the raking bar rotation axle mounted onto the boiler inside walls with a crank drive.

EFFECT: boiler structural simplification combined with efficiency and operational reliability enhancement.
