Abstract

A multi-fuel boiler is designed to have water between the inner and outer layers of a double-hulled submarine type, and the two ends form a horn. High-pressure air and fuel are injected into the horn of the inner layer at a certain ratio (controlled by a computer) and burned to produce high temperature and pressure. Then, the processed water and coal, which have reached the nanometer level, are injected into the inner layer through high-pressure air. When the high temperature and pressure enter the middle part of the boiler, the heating water pipes in the middle part provide a large amount of heat energy for the water between the inner and outer layers, and also accelerate the hot air to quickly impact the rear part. At this time, water is injected into the rear part of the inner layer, which further forms high-pressure steam. The steam is supplied to the steam turbine through several steam pipes in the rear part to generate power.

Description

[0001] Technical Field: This invention relates to a novel combustion boiler that can utilize gas, coal, and oil, and can in particular improve energy utilization efficiency, reduce environmental pollution, and save energy.

[0002] Background technology: Currently, most of the electricity on the market is generated by coal and natural gas, but their energy utilization rate is low (about 36%), thus wasting energy and polluting the environment.

[0003] Summary of the invention: In order to overcome the low utilization rate and environmental pollution of coal or natural gas (thermal power generation), this invention provides a brand-new (gas, coal and oil multi-fuel combustion boiler) for thermal power generation, thereby effectively improving energy utilization and reducing environmental pollution.

[0004] Technical Solution: The boiler is designed as a double-layered submarine-type boiler with water between the inner and outer layers. The water level is higher than that of the inner layer, forming a funnel shape at both ends. High-pressure air and fuel are injected into the funnel of the inner layer in a certain ratio (controlled by a computer) for combustion to generate high temperature and pressure. Then, processed water-coal that has reached nanoscale is injected into the inner layer for combustion through high-pressure air. When the high temperature and pressure enter the middle of the boiler, the heating water pipes in the middle provide a large amount of heat energy to the water between the inner and outer layers, and at the same time, they can accelerate the hot air to rush to the rear. At this time, water is injected into the rear of the inner layer, which further forms high-pressure steam. The steam provides kinetic energy to the steam turbine to generate electricity through numerous steam pipes at the rear.

[0005] The invention will be further described below with reference to the accompanying drawings and embodiments.

[0009] Specific implementation method: The inner layer and the outer layer are welded together by numerous (5) isolation sealing plates. The inner layer is located at the lower part inside the outer layer. Numerous (10) heating water pipes are welded in the middle of the inner layer to heat the water between the inner layer and the outer layer. Numerous (8) water inlet pipes, (6) steam pipes, (14) boiler inner layer water supply pipes, (7) inner steam pipes, (1) high-pressure air inlet pipes, (9) high-pressure natural gas pipes, (11) electronic igniters, (15) water and coal injectors, (multiple water level gauges) (7, 14, and 15 pass through the inner and outer layers respectively and are welded on top)

[0010] The operating principle of multi-fuel boilers:

[0011] During operation, the boiler is first filled with water through the (8) inlet pipe (boiler-specific water). The heated oil or natural gas and high-pressure air are injected into the bell mouth of the boiler through the (9) high-pressure natural gas pipeline. After the combustion is ignited by the electronic igniter, the amount of fuel and high-pressure air can be increased to form a high temperature. Then, the processed coal and water that has reached the micron level are injected into the boiler through the (15) coal and water injector for combustion. When the high-temperature and high-pressure hot air passes through the (10) heating water pipe, it will bring huge heat energy to the water between the inner and outer layers to heat it. When the hot air reaches the back, water is added from the outside through the (14) boiler inner layer water pipe, which will generate huge energy (release of water energy). This huge amount of steam will provide huge energy to the external gas turbine through the countless (7) steam pipes for power generation and work (the pressure at the front and back of the boiler should form a huge difference between the front and the back, which is determined by the number of (7) inner steam pipes). The steam in a multi-fuel boiler is generated from water between the inner and outer layers and between the inner and outer layers. Because the steam quality differs between the two layers, it can be used for various purposes. Such a multi-fuel boiler automatically and perfectly supplies high-pressure air and fuels under computer control, so their heat energy is fully released (due to the properties of water and coal, they cannot be used alone; water addition, fuel, high-pressure air, and steam output are all controlled by computer).
