A solid particle fuel boiler

Abstract

The invention provides a solid granular fuel boiler. The solid granular fuel boiler comprises a hopper; the lower end of the hopper is connected with a feed opening of an agitating cable; a discharge opening of the agitating cage is connected with a combustion furnace; a shaft of the agitating cage is connected with a motor; a hearth of the combustion furnace is connected with a fan, and the bottom of the combustion furnace is connected with the feed opening of the agitating cage; a coil pipe is arranged on the wall of the combustion furnace in a coiling manner; one end of the coil pipe is connected with one end of a water inlet pipe and while the other end of the coil pipe is connected with one end of a water return pipe; a water pump is mounted on the water return pipe; the other end of the water inlet pipe and the other end of the water return pipe are both connected with a tube pass of a heat exchanger; a shell pass of the heat exchanger is connected with a cold pipe and a hot pipe; a bin is formed in the upper part of the hopper; a conveyer belt bracket is mounted on the sidewall of the hopper, and a conveyer belt is mounted on the conveyer belt bracket; one end of the conveyer belt is positioned above the hopper and while the other end of the conveyer belt is positioned at the lower part of the bin; a discharging door is formed in the lower part of the bin.

Description

technical field [0001] The present invention relates to a burner, specifically a solid particle fuel boiler. Background technique [0002] At present, in the existing solid particle fuel boilers, after the solid particle fuel is ignited and burned, there are still some unburned biomass pulverized particles or sawdust, and these biomass pulverized particles or wood chips are directly discharged from the combustion furnace with the ashes, not only for the The environment causes pollution, and at the same time, it cannot be fully utilized to cause waste. The temperature of the furnace wall of the combustion furnace is high, and the long-term high temperature condition causes the aging of the furnace wall and the service life is short; the heat after the furnace wall is raised is usually lost in the air, which invisibly causes energy waste. The process of fuel input is continuous machine feeding, which may cause the phenomenon of flameout after the fuel is completely burned bef...

Problems solved by technology

Under normal circumstances, the amount of gas is small, the reason is that there is tempering phenomenon in the vent pipe, if the amount of gas is too large, the gas explosion in the vent pipe will cause a safety hazard

In the existing solid particle fuel boiler, the solid particle fuel is not fully combusted, a large amount of fuel cannot be burned, and the energy of the fuel cannot be fully released, resulting in waste; due to insufficient combustion, the fuel produces a large amount of harmful gases such as carbon monoxide in a low-oxygen state , pollute the air, and at the same time, when the concentration of carbon monoxide is too high, it is easy to explode, posing a safety hazard
