Title: Operating-time control method for solid-fuel fired boiler
Inventor: WINTRICH FRANZ
IPC: F23N5/08
Filed: 1996-02-13
Abstract: The method uses a boiler (1) with forced air inlets (2) and heat transfer surfaces (3) to heat water. Fuel is fed from a separate bunker. The exhaust gases contain residual solid matter which collects on the internal surfaces of the boiler reducing the efficiency.
