Internal combustion method

Abstract

The invention relates to an internal combustion method, and belongs to the field of combustion methods of fuel. Compared with an external combustion method, almost 100% of heat energy generated by the solid or liquid or gaseous fuel is utilized, and the heat efficiency of the fuel is improved to the maximum degree. Through the internal combustion method, the combustion intensity of flames is extremely high, and almost 100% of the fuel can be combusted by the flames of an annular side combustion chamber; a long-tube furnace is compact and simple in structure, small in size, light in weight, small in occupied area, easy to manufacture and low in total cost; coal can generate coal gas. By adopting the coal gas for electricity generation, near-zero emission is achieved, and therefore the environment can be fundamentally improved. Multiple flaming fronts exist at the lower middle portion of the long-tube furnace, are away from a smoke outlet and a furnace mouth and burn vertically, continuously and evenly in a serial connection mode in a stable area. All heat energy generated by burning of the multiple flaming fronts is stored in a hearth, then almost 100% of the heat energy acts on a peripheral water jacket in the middle of the long-tube furnace, and then high-temperature and high-pressure steam can be generated and used for cooking, heating and electricity generating.

Description

[0001] Technical field involved [0002] The invention relates to a method for burning three kinds of fuels: solid fuel, liquid fuel and gas fuel. It is essentially different from the traditional combustion method. It is the latest internal combustion annular side combustion method for short: internal combustion method. Background technique [0003] (1) There are 16 disadvantages of using coal fuel in the existing traditional combustion method: [0004] 1. The traditional combustion method is the external combustion method: there is only one burner, and the burner is at the top of the fuel, and it is close to the mouth of the chimney and the furnace. The burner is connected to the atmosphere, and the burner works directly upwards. [0005] 2. Due to the above-mentioned reasons, it cannot gather energy to store heat. Most of the heat energy will be used up immediately, and a small part of heat energy will be wasted. [0006] 3. Because it is a single fire head, its flame burn...

Problems solved by technology

[0004] 1. The traditional combustion method is the external combustion method: there is only one fire head, which is at the top of the fuel, and is close to the chimney mouth and the furnace mouth. The fire head communicates with the atmosphere, and the fire head works directly upwards.

[0005] 2. Due to the above-mentioned reasons, it cannot gather energy to store heat. Most of the heat energy will be used up immediately, and a small part of heat energy will be wasted.

[0006] 3. Because it is a single fire head, its flame burning intensity is low and it is always a red flame. The red flame is a concrete manifestation of the inexhaustible gas. The gas can only be burnt to the degree of incandescence.

[0007] 4. Heating spiral stoves using traditional combustion methods, especially civil stoves, emit black smoke when they continue to fire and add coal.

[0008] 5. Due to the use of a single burner in the traditional combustion method, the heating spiral furnace, especially the power generation spiral furnace, has an extra large and long combustion chamber. The combustion chamber is extremely large and long, tens of meters long. Flame, due to the serious lack of oxygen, its fire head must be a dark red flame, its combustion intensity is extremely low, and there must be a large amount of coal gas in the pulverized
