Abstract

The invention discloses a boiler flue gas temperature regulating device and method. The boiler includes an installation port, an air inlet and a gas outlet. The boiler flue gas temperature regulating device includes: a flow guide heat exchange plate, which is connected through the installation port of the boiler, It is located between the air inlet and the air outlet; it can reciprocate in the height direction and / or width direction of the boiler; it can exchange heat with the flue gas; the first temperature sensor is used to monitor the smoke on the side of the air outlet. Gas temperature, forming and sending the first flue gas temperature signal; the controller, the guide heat exchange plate and the first temperature sensor are all connected to the controller, and the controller is used to receive the first flue gas temperature signal and compare it with the preset temperature signal , and control the reciprocating movement of the guide heat exchange plate according to the comparison result. The boiler flue gas temperature regulating device includes: the present invention provides a boiler flue gas temperature regulating device and method, which solves the problem that the flue gas temperature of a boiler for treating hazardous waste cannot be adjusted, and avoids large fluctuations in the flue gas temperature.

Description

technical field [0001] The present invention relates to boiler equipment, more specifically, to a boiler flue gas temperature regulating device and method. Background technique [0002] When hazardous wastes are processed by boilers, due to the variety and complex composition, they may contain or generate dioxins. During the incineration process, most of them have been destroyed and decomposed. The substance will be discharged along with the exhaust gas, and will be catalyzed by metal chlorides to generate dioxins. If the exhaust gas temperature of the boiler is between 300°C and 400°C, it will provide convenient conditions for the formation of dioxins. Generally, the furnace temperature of the boiler should exceed 500°C so that the hazardous waste can be fully burned, and the exhaust gas temperature of the boiler may be as high as 550°C. Although it can curb the generation of dioxins, it will affect the subsequent treatment of the flue gas. For example, the bag filter may ...
