Permanently reliable in operation optimized combustion process for commercially available sweeper wood - gasifier - heating boiler installations

摘要

Sweeper wood - gasifier - heating boiler installations with combustion control collar, which is connected by means of a lambda probe according to din en 303 - 5 represent the s. d. t. which. The logs gasify metered in a substoichiometric level therein with primary air to a heat resistant fireclay surface. The fuel gases are centrally in the downward direction by means of a small metal combustion grate is drawn off towards the secondary combustion chamber with secondary air.This narrow nozzle is exposed to considerable chemically - physical requirements. Conventional simple ferritic steel boiler (st - 37 / h i / ip235gh...) scales produced here as a welded construction in the case of a high temperature under the influence of atmospheric oxygen with material removal through to complete destruction.A as an alternative of chromium but casting (1.4710, 1.4745, 1.4857...) combustion nozzle particularly produced in this case, on the other hand, is permanently heat - and scale-resistant up to an unlimited shelf life, in conjunction with a reduced expenditure on maintenance.
