Embodiment Construction

[0022] see figure 1 , the gas split boiler according to the present invention includes a boiler main body 4, a funnel-shaped coal bunker 2 is arranged on the top of the main body 4, and a conical carbonization chamber connected to the discharge port of the coal bunker 2 and whose lower end is close to the combustion layer of the furnace The tube 5 is provided with a fractionating cone 6 inside the distillation tube 5, and the space between the two forms a dry distillation chamber. A rotating coke pusher 8 and an air chamber 9 arranged below the coke pusher 8 are arranged under the fractionating cone 6. The air chamber 9 has a ventilation hole with a hood, and the main body 4 is also provided with a furnace door, which is located above the bottom of the retort tube 5 for ignition or inspection of the furnace.

[0023] In order to control the temperature of the retort tube 5, a water-cooled wall 7 for heat resistance and heat absorption is arranged on the periphery of the retort...

Abstract

The invention relates to a gas bypass type boiler. It includes main body, funneled bunker set on top of main body, taper dry distillation tube which communicates with discharge hatch and closes to combustion layer of hearth. There is a dry distillation prick in dry distillation tube between which dry distillation room is formed. There is a rotate coke-pushing ram below dry distillation prick and an air chamber below coke-pushing ram. The air chamber has an airway with an air cap. The stove can decoke and denitride effectively to reduce atmospheric pollution made by coal combustion in boiler. And acid rain is avoided. At the same time, the collected sulfur and nitrogen is used as resource, which can both save expense of fathering air pollution and create fortune. Enormous social and economic benefit can be made. Cokes fallen from dry distillation room diffuse around. There are carbon, fire and ash from the top down. The ash will not be coking because there is no reducing gas in it. So it can be very easily discharged from ash expeller. The invention can be applied in kinds of boilers and kiln hoods in various tons.

Description

technical field [0001] The invention relates to a boiler, in particular to a boiler which discharges two gases produced before and after coal combustion in separate flows. Background technique [0002] The boiler currently in use consists of two parts, the upper part is the pot and the lower part is the furnace. The coal burning method is to add coal horizontally, and directly add coal into the furnace for combustion, causing the coal to go through three stages in the furnace: preparation for combustion, combustion and burnout. This method of combustion results in the presence of two gases at the same time in any burning furnace. One is the volatile gas released during the coal preparation stage, and the other is the gas emitted by carbon combustion. Although these two gases exist in the furnace at the same time, the time and space they produce are different. A volatile gas that is produced during the preparation of coal for combustion and is a mixture of hydrogen, oxygen...
