Problems solved by technology
The regenerative small gas turbine invented by the China Aviation Power Machinery Research Institute [Patent Publication No. CN10128076] performs heat energy exchange through a corrugated plate heat exchanger. The unit volume heat transfer area is large, the flow loss is small, and the heat recovery efficiency can reach 0.7-0.95; small The thermal efficiency of the gas turbine can reach 35-50%. This gas turbine uses a corrugated plate heat exchanger, and the fuel is fuel oil instead of using low-calorific-value gas, which does not solve the problem of stable combustion and power generation of low-calorific-value gas.

Abstract
The invention discloses a generator provided with a switching catalytic combustion gas turbine in the technical field of dynamic power generation, wherein the outlet and the inlet of an air filter are connected with low calorific value fuel gas, the outlet of the air filter is connected with the inlet of a centrifugal compressor, the outlet of the centrifugal compressor is connected with the inlet of a four-way valve, the outlet of the four-way valve is connected with one end of a catalytic combustion chamber, a heat accumulator at the other end of the catalytic combustion chamber enters a centripetal turbine, the outlet of the centripetal turbine is connected with the atmosphere directly, a flam ignitor is started and inserted in a cavity of the catalytic combustion chamber, the centrifugal compressor is coaxial with the centripetal turbine, an output shaft at the centrifugal compressor end is connected with a high-speed shaft of a reduction gear box through a shaft coupling, and a low-speed shaft of the reduction gear box is connected with a generator shaft through the shaft coupling. The fuel net content of the low calorific value fuel gas adopted by the generator is less than 5 percent and the heat value of the low calorific value fuel gas is lower than 2 MJ / NM3, and the generator adopts catalytic combustion so that the fuel gas is usually exhausted into the atmosphere directly, and not only the energy is used but also the discharge of greenhouse gas is reduced.
Description
Switching Catalytic Combustion Gas Turbine Power Plants technical field The present invention relates to a power generation device in the technical field of power generation, in particular to a switching catalytic combustion gas turbine power generation device. Background technique The calorific value of low-calorific gas is less than 5MJ / Nm3, with a wide variety and a huge amount, including mine ventilation gas, some coalbed methane and biomass gas, and by-products with very low methane (CH4) concentrations in steel and chemical industries Gas, a large part of which is ultra-low calorific value gas less than 2MJ / Nm3, and the concentration of methane (CH4) is only 0.5% to 5%. Due to the low concentration of methane, it cannot be ignited and burned by conventional methods, and it is quite difficult to use it in practice. Most of the ultra-low calorific value fuels are discarded, and the waste of energy is astonishing. The total amount of methane emitted into the atmosphere...
