Boiler combustion explosion-proof equipment

Abstract

The invention belongs to the field of boiler explosion prevention, and particularly relates to boiler combustion explosion-proof equipment which comprises a boiler body, an upper feeding chamber is installed above the boiler body, a side feeding chamber is installed on the side edge of the boiler body, and a steam pipeline is fixedly arranged on the side, close to the side feeding chamber, of the upper feeding chamber. An anti-explosion module is arranged below the steam pipeline in the boiler body, a first anti-explosion baffle and a second anti-explosion baffle which are used for preventing further deflagration and the like are arranged on the anti-explosion module in a sliding mode, the first anti-explosion baffle is close to one side of the upper feeding chamber valve, and the second anti-explosion baffle is close to one side of the side feeding chamber valve. A switching module for changing the pressure relief flux is arranged in the anti-explosion module, a first-stage air inlet channel is formed in the side edge of the steam channel, and multi-stage targeted treatment can be conducted on the air pressure in the boiler, and pretreatment can be conducted on uncontrollable explosion.

Description

technical field [0001] The invention belongs to the explosion-proof field of boilers, and in particular relates to explosion-proof equipment for boiler combustion. Background technique [0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. [0003] Improper ignition or operation of chamber-fired boilers fueled by pulverized coal, oil or combustible gas may cause deflagration or secondary combustion in the furnace or tail flue, resulting in an increase in the pressure in the furnace. During the operation of the boiler, Because some parts of the pressure components exceed the ultimate strength of the material, the weak part breaks, or some boiler pressure parts are damaged due to the explosion of the furnace door, so that the water and steam stored in the boiler immediately flow fr...

AI Technical Summary

Problems solved by technology

[0005] ①In the event of an explosion, there is no way to deal with the explosion in the existing equipment. Except for a small part of the energy released when the boiler explodes, it is consumed in tearing the steel plate, breaking some fragments, and steam and water pipes, valves and bodies connected to the boiler. Throwing away from the original place, most of the remaining energy will act on the surrounding environment in the form of shock waves, causing damage to buildings and casualties

[0006] ②The pressure relief method during the operation of the boiler is single, and there are few response situations, and it is impossible to deal with the air pressure changes during the operation in detail
