Pulverized coal industrial boiler system

Abstract

The invention relates to a pulverized coal industrial boiler system. The pulverized coal industrial boiler system is characterized by comprising a pulverized coal feeding and separating filter, a pulverized coal storing and feeding device, a boiler burner, a flue gas integrated treatment device, a fly ash delivering and storing device and an inert gas protecting device; the feeding and separating filter filters pulverized coal and then conveys the pulverized coal to the pulverized coal storing and feeding device, the pulverized coal storing and feeding device stores the pulverized coal and supplies the pulverized coal to the boiler burner, the boiler burner exchanges heat with a thermodynamic system during the burning process and supplies hot water or steam to users; and flue gas after the combustion of the boiler burner is treated through the flue gas integrated treatment device and is delivered to the fly ash delivering and storing device, wherein the pulverized coal in the pulverized coal storing and feeding device needs to be protected through inertia gases which are provided by the inert gas protecting device during the storing process. The system integrates pulverized coal delivering, storing, feeding, flue gas treating and recycling into a whole, has high function integration level, a small occupation area, low operation cost, high economy and no dust and flue gas leakage, cannot cause environmental pollution and can be widely used for a pulverized coal feeding process.

Description

technical field [0001] The invention relates to a boiler system, in particular to a pulverized coal industrial boiler system integrating pulverized coal transportation, storage, feeding, flue gas treatment and recovery. Background technique [0002] At present, the pulverized coal boiler system is widely used in large power plants, but it is rarely used in the field of industrial boilers. There have been some related researches and products in the last century, but they all died due to some disadvantages and unsound systems. The current general situation of coal-fired industrial boilers is low thermal efficiency, huge energy waste, and serious pollution (especially smoke and sulfur dioxide). Therefore, there is an urgent need to study an energy-saving and emission-reducing system suitable for industrial boilers, so as to comply with the national energy-saving and emission-reduction policies and solve the problem of low technology and equipment levels in the coal-fired indust...
