Hydrogen combustion-supporting device and method

Abstract

A hydrogen combustion-supporting device comprises an alcohol vaporization device, a hydrogen generator and a flame gun. The alcohol vaporization device comprises an evaporator and is characterized in that the evaporator comprises a body, a plurality of rows of circular tubes are arranged inside the body, heating catalytic agents are placed in the circular tubes, a plurality of micropores are formed in the peripheries of the circular tubes and filled with steel balls, and liquid alcohol flows through the micropores and is vaporized by the aid of heat energy released by the heating catalytic agents. According to a method for hydrogen combustion-supporting by the hydrogen combustion-supporting device, gas alcohol generated by the alcohol vaporization device and hydrogen generated by the hydrogen generator are jointly guided into the flame gun and combust after being mixed with air. The combustion efficiency of fuels is increased, and contaminants such as nitric oxide (nitric oxide) or carbon black in exhaust can be decreased.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a hydrogen combustion-supporting device and method. Background technique [0002] Existing boilers or heating equipment use natural gas, diesel or heavy oil (commonly known as fuel oil, Fuel oil) as the main fuel, sometimes mixed with some relatively low-priced recycled oil or solvent to save fuel costs. In recent years, with the successful development of natural gas as a raw material, the production cost of alcohols has been reduced. On the other hand, the carbon dioxide released by the combustion of alcohols is much lower than the above-mentioned common fuels. Therefore, using alcohol as fuel can provide a low-carbon fuel, and it is competitive in price. [0003] However, alcohols are liquid at room temperature, so when used, they must be vaporized into gaseous state before entering the torch and burning with air to improve combustion efficiency. Most of the c...

Problems solved by technology

In addition, the direct heating method is difficult to sensitively control the feed amount of alcohol vapor, and the feed amount of alcohol fuel needs to be changed to adjust the intensity of the flame, which is difficult to control at will.

Moreover, the direct heating method directly contacts the electric heater with the alcohol. Once the insulator of the electric heating equipment is damaged, there will be a safety hazard.

When the heating is stopped, the alcohol in the container still maintains the boiling temperature, continues to evaporate and keep warm, resulting in a waste of energy

The indirect heating method relies on the heating of the water bath. On the one hand, the evaporation temperature and speed cannot be adjusted sensitively. On the other hand, when the heating is stopped, the temperature of the water bath remains at a high temperature, which makes it difficult to immediately cool down and causes greater energy waste.
