Central heating boiler for burning e.g. coke, has chimney with housing enclosing combustion chamber and including openings for draft and flowing of waste gas, and control unit adjustably mounted in boiler regulating flue gas speed

摘要

The boiler has a chimney with housing that encloses a filling and a combustion chamber and including openings for draft and flowing of waste gas. A fuel air mixture is burned, where the pressure of the fuel determines a flue gas speed (3) that is adjustable in a chimney pipe (9) over a control unit and a servo motor (6). The control unit that is adjustably mounted on the boiler regulates the flue gas speed.
