Abstract

The invention discloses a smokeless boiler which comprises a combustion hearth and a high-temperature combustion supporting chamber. The smokeless boiler is characterized in that the smoke dust ascending position of the boiler hearth is provided with the high-temperature combustion supporting chamber, and therefore smoke dust formed after combustion reaction of fuel in the hearth is subjected to purifying combustion reaction again to achieve dustless emission.

Description

Technical field: [0001] The invention relates to a smokeless boiler, which can be used, for example, in steam and hot water production boilers in industrial production and civil heating. Background technique: [0002] At present, all boilers use single furnace and grate technology. In use, the flue gas still cannot carry out fundamental secondary combustion. Although some boilers have added dust removal and sulfur removal devices, there are still A large number of combustible gases and particles not only cause environmental pollution, waste resources, but also increase production costs. The exhausted flue gas must be treated by special equipment, so the efficiency is very low, environmental pollution, and waste of resources are very serious. Invention content: [0003] The present invention is proposed in view of the above problems, in order to provide a new type of smokeless boiler, which can make the flue gas and dust after the primary combustion undergo secondary combus...
