Boiler for producing steam by combusting SiC crystals and method for producing steam

Abstract

The invention discloses a boiler for producing steam by combusting SiC crystals and a method for producing the steam. The boiler comprises a shell, wherein the shell is provided with a water replenishing pipe and a steam pipeline; a combustion chamber is formed in a water storage cavity; an exhaust pipeline is arranged on the top of the combustion chamber; a laser source and an oxygen supply pipeline are arranged on the side wall of the combustion chamber; the oxygen supply pipeline is connected with an oxygen station; and a material supply branch pipe is arranged on the oxygen supply pipeline and is connected with a powder metering filling machine. The method for producing the steam comprises the following steps of: sieving SiC crystal powder by using a sieve screen; mixing silicate crystal powder and the SiC crystal powder in a ratio, adding a bonding agent, compressing by a press machine, and cutting into crystal mixed blocks; putting the crystal mixed blocks into the combustion chamber, and irradiating by using a laser beam, so that the crystal mixed blocks are combusted; introducing oxygen and the SiC powder into the combustion chamber by the oxygen supply pipeline; and controlling a water level in the water storage cavity. According to the boiler, the high-pressure steam applied to fields of heating, power generation and the like can be produced by replacing coal with SiC serving as fuel.

Description

Technical field [0001] The invention relates to a device and method for preparing steam, in particular to a boiler for preparing steam by burning SiC crystals and a method for preparing steam. Background technique [0002] At present, my country’s electricity supply is still dominated by thermal power generation. According to statistics, my country’s thermal power generation accounts for more than 75% of the country’s annual power generation. Most of the thermal power plants use coal as fuel to generate heat by burning them. The water is heated to produce high-pressure steam to drive the generator to generate electricity. However, when coal is burned, it will pollute the environment. The SO 2 , NO x Waiting for acid gas will increase the acid rain, and the fly ash discharged after combustion will float in the air, which will have a negative impact on people's lives and plant growth. At present, the power industry has become one of the largest pollutant emission industries in my ...
