Abstract

The invention relates to a combustion system with a coal water slurry fired boiler. The combustion system comprises a coal water slurry storage tank, a stirrer, a slurry supply pump, a filter, a combustor and the boiler which are sequentially connected with one another, wherein the combustor is respectively provided with an air-blast system and an ignition oil way which are used for atomizing coal water slurry, the air-blast system comprises an air storage tank and an air compressor acting on the air storage tank, the air storage tank is connected with the combustor, and the ignition oil way comprises a daily oil tank and an ignition oil tank which are sequentially connected with the combustor. The combustion system totally adopts flow conveying and atomization of pipelines, can implement automatic ignition of oil in a short time, is simple and convenient to operate and high in safety, and requires labor intensity which is much less than that required by a coal-fired boiler.

Description

technical field [0001] The invention relates to the technical field of boiler combustion, in particular to a coal-water slurry boiler combustion system. Background technique [0002] Existing coal-fired boilers have relatively high labor intensity, but relatively low safety, and insufficient low-temperature combustion will cause heavy pollution when coal-fired boilers are fed; Nitrogen oxides pollute the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal-water slurry boiler combustion system in order to overcome the deficiencies of the above-mentioned technologies. [0004] The technical solution adopted by the present invention to solve the technical problem is: a coal-water slurry boiler combustion system, including a coal-water slurry storage tank, agitator, slurry supply pump, filter, burner and boiler connected in sequence, the The burner is respectively equipped with a blowing system and ...
