In the boiler system of the present application, the heat source supply device having the plasma generating unit 3 and the air intake unit 2 is provided to generate high-temperature and high-temperature working gas, and the working gas is guided to the accumulator 53 in the boiler 5 to be collected, and the water in the boiler 5 can be heated to be steam at about 130 ℃ by heat accumulation and heat release of the accumulator 53, so that the working gas enters an industrial or civil production link.

Then, the working gas with a certain waste heat enters the ceramic heat exchanger after passing through the boiler 5, and at the moment, the working gas flowing through the ceramic heat exchanger can heat the copper water pipe to 100 ℃, and the water in the copper water pipe is conveyed to the steam boiler 5, so that the high-temperature steam with the temperature of more than 130 ℃ can be continuously generated only by slightly heating the ceramic heat accumulator in the boiler 5, and the output rate of the steam is improved.

At this time, the working gas continuously flowing in the ceramic heat exchanger still has a certain temperature, and at this time, the boiler system of the application carries out secondary utilization on the working gas by arranging the waste heat power generation device 7.

Then, the temperature of the working gas after the waste heat power generation still reaches about 60 ℃, and at the moment, the working gas is reintroduced into a heat exchanger (heat exchanger), wherein the heat exchanger is filled with the warm water and performs heat exchange in the heat exchanger. The warmed warm water is introduced into the heat source supply device for cooling, then is conveyed into the ceramic heat exchanger, and enters the boiler 5 after being warmed by the ceramic heat exchanger, so that a virtuous circle steam supply system is formed.

In addition, the boiler system of the application realizes the recycling of gas, and the working gas is conveyed into the heat source supply device through the air inlet component 2 to form high-temperature high-speed working gas, and the working gas enters the energy accumulator 53 in the boiler 5 to form a complete closed loop heating (heat source supply), so that the generation of pollutants in the combustion process of the boiler 5 is reduced, and the environmental protection performance of the boiler 5 is improved.

The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
