A self-purifying dust removal low noxsox condensate type super-efficient four-chamber three-circulation coal-water slurry boiler

Abstract

A self-cleaning and dust-removing low NOxSOx condensate type super-efficient four-chamber three-circulation coal-water slurry boiler, especially equipped with a dry-heat furnace, the chamber is equipped with a coal-water slurry burner, a temperature-controlled sewage burner, a convective heat exchange chamber, and an ash separator. The four-chamber structure of the chamber and the condensate-type heat-absorbing superconductor bundle chamber realizes the energy saving of about 25% compared with the current coal-water slurry boiler. The functional configuration of "waste heat recovery" will fundamentally solve the problem of coal-burning pollution in my country and even the world and the current coal-water slurry technology is restricted by the water content of 35-45% and cannot reuse latent heat, providing coal-water slurry boilers for the whole country The real possibility that the economy of life, industry and power generation operation comes first.

Description

technical field [0001] The present invention and a self-cleaning dust removal low NOxSOx condensate type super-efficient four-chamber three-circulation coal-water slurry boiler technology, especially equipped with a dry-heat furnace, a coal-water slurry burner, a temperature-controlled sewage burner, and an upper and lower guide The convective heat exchange chamber of the smoke wall flushing tube bundle is equipped with a centrifugal flue gas dust ash powder recirculation ash separation core chamber and a four-chamber structure of a water-condensing heat-absorbing superconductor bundle chamber to achieve complete combustion, desulfurization and nitrogen reduction, and ultra-clean dust removal , Incineration of industrial sewage and full recovery of sensible heat and latent heat "coal-water slurry, concurrent incineration of sewage, low NOxSOx, ultra-clean dust removal, condensate water recovery, waste heat recovery" function configuration as one super-efficient four-chamber thr...

Problems solved by technology

However, since 34-40% of the water not only does not contribute heat in the combustion process of coal-water slurry, but absorbs a large amount of heat and causes excessive latent heat loss... Around this defect, there are many fields of production and application of coal-water slurry Constitutes several bottlenecks in the development of coal water slurry business
