High-efficiency micro-discharging fire coal hot water boiler

Abstract

The invention relates to a high efficiency micro-discharge coal-fired hot water boiler. A smokeless chimney is installed with a low smoke discharging temperature, high thermal efficiency, a quick temperature elevating speed and high combustion efficiency. Since the chimney is smokeless, discharging indicators tend towards zero, so that effects of little burn, little discharge, scientific control, environmental protection and energy saving are implemented. The inventive boiler comprises a boiler body, one side of the boiler body is connected to a coal feeder, and the other side of the boiler body is connected to a fume channel waste heat recovery system which is connected to a desulfurization dust removing system. The boiler body comprises a combustion chamber, a chain grate is disposed under the combustion chamber, a main internal furnace and an accessorial internal furnace both of which are used as internal furnaces and communicate with each other are disposed above the combustion chamber sequentially, a water inlet is disposed on the main internal furnace, a hot water outlet and a smoke discharging pore are disposed on the accessorial internal furnace, and a fire averaging plate connected with a boiler crown is disposed in the combustion chamber. Heat transfer steel tubes are disposed in the main internal furnace and the accessorial internal furnace, a set of heat transfer steel tubes used as fire path one is disposed in the main internal furnace, and two sets of heat transfer steel tubes used as fire path two and fire path three respectively are disposed in the accessorial internal furnace.

Description

1. Technical field: [0001] The invention relates to a boiler, in particular to a high-efficiency micro-emission coal-fired hot water boiler. 2. Background technology: [0002] In the background technology, environmental protection and energy saving have become two major themes in the development of modern civilized society, and also two important battles in my country's future economic and social development strategy. Boilers are not only an important tool for industrial economic development, but also an indispensable crutch for human life. At the same time, boiler emissions are closely related to people's daily life environment. Therefore, the development of environmentally friendly and energy-saving boilers with high efficiency, low consumption, low emissions, and low pollution is a major event that benefits mankind and contributes to society. [0003] In my country's fossil resources: coal accounts for 95.4%, oil only 3.3%, and natural gas only 1.3%. The realistic energ...
