Description

Composite slag remover for biomass furnace

Technical Field

The utility model belongs to the field of slag remover equipment for boilers, and particularly relates to a composite slag remover for a biomass furnace.

Background

Along with the further development of science and technology, the requirements on environmental protection and energy saving technology in the technical field of boilers are higher and higher, and especially the most stringent environmental protection method in history is brought out, the more stringent requirements are put forward for the gas emission of the boiler industry, and the innovation and innovation of the coal-fired boiler are imperative. Biomass such as straw is used as fuel, and is low in cost, renewable, low in emission and widely used at present.

However, the existing slag remover of the biomass boiler is a slag remover of an original coal-fired boiler, the biomass boiler, especially the boiler for burning straw, is a slag remover of the coal-fired boiler, and because of the change of fuel, the slag remover has a plurality of defects in the application of the biomass boiler, and because of a certain reason, the straw is not burnt completely, namely stems and leaves. Both stems and leaves of biomass can cause blockage or even holding down of the slag remover, resulting in failure or damage of the slag remover; the slag remover of the coal-fired boiler cannot play any role in removing the phenomenon due to the fact that unburned carbon ash and straw float in the water of the slag remover.

Therefore, the existing slag remover for the biomass furnace is a main problem in the popularization and application process of the biomass boiler and is a ridge which is needed to be surmounted. The composite slag remover for the biomass furnace, which is researched and developed by the inventor, thoroughly solves various defects and overcomes all difficulties.
