Combustion chamber for central heating boiler - can operate either on liq. or gaseous fuel

摘要

A central heating boiler is designed to operate on either a liq. or a gaseous fuel. The fuel is supplied through a pipe (12) and is atomised by a nozzle (13) which injects it into the combustion chamber (7). A steam superheater formed by a coil of pipe (24) is installed in the combustion chamber (7) and generates superheated steam which is injected into the combustion chamber (7) in front of the fuel atomising nozzle. The combustion gases then flow through a ceramic heat exchanger which heats the water for the central heating system. USE - Central heating boiler.
