Abstract

The invention relates to a coal burning system with a safety protection function. The coal burning system comprises a coal burning hearth and a burning device used for burning dry gas discharged from the coal burning hearth. The burning device comprises a burner, a feeding system and a frequent-blowing device. A dry gas inlet of the feeding system is connected with a dry gas discharge outlet of the coal burning hearth. A dry gas outlet of the feeding system is connected with a feeding port of the burner. A by-pass emptying valve used for discharging dry gas in the feeding system is arranged inside the feeding system. When the coal burning system operates normally, gas supply of the burner is stopped, and the by-pass emptying valve is normally opened; when the burner operates, the by-pass emptying valve is normally closed; once dry gas leaks or dry gas remains in a pipe, the dry gas is discharged through the by-pass emptying valve. According to the coal burning system with the safety protection function, if the dry gas leaks or the dry gas remains in a pipeline, dangers and hidden dangers can be eliminated as long as the emptying valve is opened, so that the coal burning system is convenient and quick to use, and high in security coefficient.

Description

technical field [0001] The invention relates to a waste gas combustion system of a coal-burning system, in particular to a coal-burning system with safety protection. Background technique [0002] Many chemical processing plants in China currently use a large number of heat transfer oil boilers. The processing equipment will produce some combustible gases, such as dry gas, etc., and some sulfur dioxide and hydrogen sulfide are contained in the dry gas. Hydrogen sulfide must be fully burned before being discharged into the atmosphere, and flue gas must be desulfurized to minimize pollutant emissions. A large amount of waste gas from chemical plants is directly fed into the torch for combustion, and the calorific value of the waste gas is mostly above 5000 kcal / cubic, which is very ideal and the waste is serious. A burner interface is added on the side of the furnace for mixed combustion. However, the high temperature zone of the furnace will damage the burner joints and noz...
