Abstract

The invention discloses a modularized pulverized coal clean combustion device, relating to a combustion device for a boiler. The modularized pulverized coal clean combustion device comprises a cylindrical burning chamber arranged in the foreside of the boiler; the central part of the upper head face of the burning chamber is provided with a cyclone burner; the middle of the burning chamber is provided with a shrinking waist which divides the burning chamber into an upper burning chamber and a lower burning chamber, wherein the upper burning chamber is connected with a primary wind pulverized coal inlet with direct current incision; the upper and the lower burning chambers are connected with a secondary wind spout with direct current incision; the central part of the bottom of the lower burning chamber is provided with a mouth; a detritus tank is arranged on the corresponding position of the mouth; the tail of the lower burning chamber is connected with the boiler through a burnout chamber. The modularized pulverized coal clean combustion device can be directly in modularized butt joint with a pressed body of the prior boiler, is suitable for burning various pulverized coals, improves thermal efficiency, replaces the prior coal blocks or fuel gas as fuel and has good environment-friendly effect.

Description

Modular pulverized coal clean combustion device technical field The invention relates to a combustion device for a boiler, in particular to a modularized pulverized coal clean combustion device which can be used as a fuel to replace lump coal and fuel gas. Background technique The transformation of small and medium industrial boilers and the replacement of new high-efficiency boilers are the first of the top ten energy-saving projects in the country's "Eleventh and Five-Year Plans". At present, a large number of industrial boilers (kilns) use layer combustion, or burn oil and gas. Layer-fired furnaces are suitable for burning bituminous coal, and their thermal efficiency is generally low, while fuel gas is expensive. With the breakthrough of pulverizing technology, the cost of small-scale production of pulverized coal has been greatly reduced, so that the pulverized coal combustion method can also be applied to small and medium industrial boilers (kilns). Therefore, ch...
