Multi-fire head continuous balanced combustion method and long-tube rotary stove derived therefrom

Abstract

The invention discloses a multi-fire head continuous balanced combustion method and a long-tube rotary stove derived therefrom, and belongs to coal combustion methods and coal stove utensils. The long-tube rotary stove can produce a dozen of fire heads, large fire and extremely strong firepower under the action of a fire combustion chamber. Compared with the conventional coal stove, the long-tuberotary stove has the advantages that: coal resources can be saved to the greatest extent; coal gas can be used to the greatest extent; combustion strength of the coal gas can be increased to the greatest extent; heat energy is utilized to the greatest extent; environmental pollution is greatly improved; the stove body of the new stove can combust the coal gas in a reverse direction after being turned 180 degrees; the long-tube rotary stove consists of components such as a stove plate, a middle fire cover, a coal support, a stove body, a fire combustion chamber, a lower fire cover and the like; the components are arranged on the stove body in sequence; the long-tube rotary stove is used for heating, cooking meals, sweeping snow and cutting ice; and an external combustion vehicle and a generator are driven by using the long-tube rotary stove, so that a generating power equipment system is greatly simplified.

Description

technical field [0001] The present invention relates to various coal resources, a multi-burner continuous balanced combustion method and a new stove derived from it. Especially Fengwo coal stove and other coal stoves. Background technique [0002] 1. Single burner intermittent and uneven combustion method [0003] The traditional combustion method is a single fire head. Every time new coal is added to the fire, the new coal will extinguish the flame, and the flame will reappear after more than ten minutes of smoking. This kind of ignition-and-off-and-on, intermittent, and uneven furnace temperature combustion characteristics, I call it: single burner intermittent and uneven combustion method, abbreviated as: traditional combustion method. [0004] The traditional combustion method is to burn coal; it is a piece of coal plus a piece of coal to burn intermittently. In fact, what is burned is the coal gas (the general term for all flammable gases) produced after the coal is h...

AI Technical Summary

Problems solved by technology

[0011] ③The burner burns in a large space and a very long combustion chamber, and a large amount of non-combustible gas reduces the flame burning intensity of the burner

It is also a contradiction that pulverized coal furnaces and circulating fluidized bed boilers cannot overcome.

[0012] ④ Coal powder flows from high temperature area to low temperature area, resulting in less and less gasification of coal, that is, incomplete combustion of coal gas

[0013] ⑤ Reheaters, economizers, preheaters, and boiler structures with inverted exhaust smoke cannot do without them. With them, the furnace temperature changes greatly, which is not conducive to the gasification of pulverized coal

[0018] 1. The furnace mouth is on the upper part of the coal stove and close to the mouth of the chimney, so that all old stoves can only be heated, boiled water, and cooked through the open flame on the furnace mouth. The hotter the fire, the more heat energy will be discharged through the chimney .A lot of heat energy is wasted in vain. Especially bituminous coal not only emits a lot of heat energy, but also emits a lot of gas, that is, black smoke and white smoke. These are all resources. And it also seriously pollutes the environment

The old stove can not make full use of heat energy, so that more than 30% of the heat energy is discharged from the furnace, and the heat loss is extremely serious

[0019] 2. Take the 4-piece Fengwo coal stove as an example. In this kind of stove, the oxygen consumption of the 4 pieces of coal is very unbalanced. The strong fire competes for the most oxygen, so the fire burns the most vigorously and the temperature is the highest, thus forming air The strong convection phenomenon. The medium fire is the second, and the weak fire is the most oxygen-deficient coal. In addition, the strong convection of the air causes the temperature at the bottom of the furnace to be very low. Finally, the fire has to be extinguished in the case of black core (that is, the coal is not completely burned). This kind of situation caused by this kind of stove is repeated cycle and is constant. Therefore, the coal in the peak nest is not completely burned.

[0020] 3. The hearth of the old stove is short and the coal is less. Therefore, when discharging the slag, it is either a weak fire coal or a slight fire coal. In short, it is discharged with a large amount of waste heat, and the heat energy is wasted in this way

[0021] 4. When the old stove is discharging dregs, it is usually eaten and vomited whole. That is to take (spit) 4 pieces of coal from the stove and put them on the ground. Then remove the exhausted coal, and then put the first 3 pieces of coal Put another piece of new coal into the furnace. The consequences of this method of slag removal are as follows: ①Put the red-hot coal indoors, which wastes a lot of heat energy and causes indoor air pollution. Although it is only a short period of two For three minutes, it choked people so badly that they had no choice but to open the door to let off the gas, which caused the temperature of the furnace to drop, forming a vicious cycle of waste. Coal, to dampen part of the fire and heat

Another waste of energy.

[0022] 5. The hearth of the old stove is short and thick, in order to make the coal burn more vigorously

[0024] 7. The old stove has only one burner, the fire is small and weak

Use it to sweep snow and remove ice, it will become very easy
