Water vapor is made and sprayed through a nozzle and then mixed with air by providing an additional electric heater or a heating tube in a gas combustor. Alternatively, the water is heated to make a water vapor and then the water vapor is sprayed or supplied and combusted together with gas, or sprayed and re-combusted directly after the primary combustion of gas by integrally forming an electric heater, a heating piping, and a heating chamber in a gas burner itself.

Description

Combustor combusted by mixing gas of oil or gas with water vapor (2) {buler (2)}

The present invention relates to a combustor that burns water by injection of steam and water into oil or gas to generate high calorific value by pyrolysis of steam due to high heat during combustion of oil and gas, thereby heating the heat transfer part to increase the amount of heat.

Conventionally, physical and chemical methods have been used as a method of mixing water with oil in order to use high calorific value during thermal decomposition of water molecules.

The dilution method of water and oil required additional expensive equipment due to the viability of the dilution and the mixing by the fine particles of the diluent particles. The chemical method used the diluent to add additional and transport costs. .

The present invention is installed in the oil burner and gas burner by a simple heating steam generator or fine spray to vaporize and mix water with oil or gas to generate primary combustion heat and generate secondary combustion heat due to thermal decomposition of water to heat the boiler. It is about the combustion method that heats wealth to high heat and reduces oil or gas consumption.

The method of vaporizing water is to vaporize an electric heating tube or use a fine spray nozzle, and to vaporize the water by spraying the heated portion with combustion heat, and to vaporize water and oil by heating and steaming it with a heating tube. can.

Water is poured into oil at a rate of 30 to 25% and then vaporized by heating tube or electric heating to be sprayed by each exposure, or heated and mixed in a vapor state to spray with the same furnace.

The heating tube can be heated by combustion heat or electric heater, and the electric heater can be vaporized initially and used before the water or oil is vaporized in the heating tube and can be heated continuously to generate superheated steam.

The method of burning by vaporizing and mixing with a fine line can be installed in double and used by mixing water spray on the primary fuel to be used.

Pyrolysis of water causes the combustion of air, oil and water by vaporizing and mixing them together at the same time, or by burning oil or gas first and then spraying water with steam or furnace spray later.

Water can be injected into the existing combustor or steam can be heated using a heating tube to make it combustible.

The present invention will be described in detail according to the structure and effect according to the configuration method.

In the steam mixing method, the heating tube and pump nozzle spraying method of its own heat source control water injection rate and steam discharge control, and when heated by electric heater and the pump is electric control to draw oil or gas supply and water mixing ratio Considering the control method can be used.

In the heating injection formula (Fig. 1), the primary combustion with a gas or oil furnace, the water forms a heating tube or a superheater tube (1) and heats it to vaporize it, and ejects it by heating it by mixing air, oil, and steam with a steam jet.

The heating tube enlarges the diameter or forms a water separation space so that only the steam is ejected. The steam outlet 2 forms a jet around the gas or oil exposure and mixes with the air first.

The steam outlet 2 is first burned by oil or gas, and then superheated through the secondary heating unit, and then ejected into the secondary air and steam to be reburned with secondary air and steam.

It is possible to have a simple structure by using a heating tube as a combustion cylinder and a flame guide plate as a secondary heating unit.

The water supply of the heating tube (Fig. 2) is supplied to the water level side (5) at a constant level by buoyancy to replenish water vaporized or supply a certain amount with an electronic pump. The amount of water replenishment is controlled by the level control or control valve to adjust the mixed combustion rate of fuel and water, or to control the flow rate according to the temperature so that the water supply amount is the best flame temperature (or light intensity).

Injection nozzle type (Fig. 3) is formed in a single body (6) in a double structure of the nozzle and the nozzle injection amount is sprayed in the vaporized state by spraying or heating oil or water with an electric heater to control the respective flow rate in the electronic pump.

Water and oil are rotated at high speed with the mixing pan (3), revolving and sprayed.

The mixing pan gives a gap (8) in a spiral (7) to reach the vortex and is transferred to the center (9) again to form a repeating vortex to dilute the oil and water and to form a circulation space (11) in the impeller fan (10). It forms and dilutes circulating vortex, and when it is rotated by Sinook wing 12, it blocks the outlet space so that pump pressure is not generated and only vortex is formed to dilute water and oil. Mixing fan gives gap of general pump and decreases the pump pressure and revolves, forming vortices and diluting water and oil.

The gas combustor (FIG. 4) pumps water into an electronic pump, sprays water into an furnace, dilute and burns water and gas in an atomized state, and heats water with an electric heater 13 to mix the gas with a superheated steam to combust it. The mixing ratio of gas and steam is the flow control valve, and the water level control valve and the electronic pump can control the amount of water. In this case, the amount of steam can be controlled by controlling the electric heater power.

In the furnace injection or steam injection by the electromagnetic pump, the heating part 14 is formed by the heat of combustion in the combustion part to generate superheated steam and mixed combustion with the gas, or first burn the gas and air and then the superheated steam by the heat of combustion. Can be burned.

Water can be first burned with an electric heater to burn superheated steam with the gas, or gas and air can be reburned after first burning the gas and air.

The construction method (Fig. 5) consists of an electronic pump 15, an electric heater 16, a heating tube 17, a veterinary control valve 18, a mixing fan 19 and a flow control valve and electric control. It burns after being burned with oil or gas, and shuts off first to stop the remnants of moisture.

The steam combustor is made of a separate electric heater or heating tube or sprayed with a furnace to supply air and mixed with air. The gas burner forms an electric heater, a heating tube, a heating tube, and is sprayed or supplied and heated to vaporize water. Combustion is carried out together with the gas or the steam is ejected immediately after the first combustion of the gas to reburn.

The control amount of oil and water can control the flow rate when spraying and working, the steam generation can be controlled by electric heater, and the combustion temperature is controlled by flame temperature or light sensor to maintain the best mixing ratio of oil or gas and water.

For first set combustion of gas or oil, it is first combusted with oil or gas and air, and the generation temperature is set to the reference temperature, and the amount of water vapor is increased by controlling the flow rate of the inflow or the heater and increasing or decreasing the temperature to increase the temperature of the oil. Provide feedback control to reach temperature.

By heating the combustion heat and superheated steam of oil and generating additional combustion heat in the process of pyrolysis of water vapor, high heat is transmitted to the flame section, combustion chamber and the heat transfer section to save fuel by the amount of steam added.

A device that burns by vaporizing or spraying water in a vaporized state can be easily attached to reduce manufacturing costs. Combustors such as gas burners can be used by simply attaching a device that vaporizes water with a water injection line or heating tube.

The injection nozzle can use oxygen torch type when gas or steam is supplied, and can combine the fluid and water nozzles.

It can be vaporized by spraying or heating for mixed combustion of oil and water, mixed in gaseous state, and burned with superheated oil sesame and / or gas with superheated steam.
