An anti-slagging gas turbine combustor using biomass fuel

Abstract

The invention discloses a slagging-preventing gas turbine combustion chamber with biomass fuel utilized. The slagging-preventing gas turbine combustion chamber comprises the combustion chamber, an air layer and a cylinder sleeve layer which are sequentially arranged from inside to outside. The bottom end of the combustion chamber is arranged in an annular clamping groove in the top end of a slag collector, a combustion chamber air inlet and a fuel inlet channel are sequentially formed in the top end of the combustion chamber from bottom to top, and a plurality of layers of hole-shaped fire grates are arranged in the combustion chamber. An air layer air inlet is formed in the bottom end of the air layer, and an air layer air outlet is communicated with the combustion chamber air inlet. The two ends of the cylinder sleeve layer are connected with the air layer through bearings, and the side wall of the cylinder sleeve layer is provided with a cylinder sleeve layer air inlet and a cylinder sleeve layer air outlet. Fan blades are arranged on the outer wall of the air layer in the circumferential direction. An air outlet of a compressor is communicated with the air layer air inlet and the cylinder sleeve layer air inlet. Fuel gas combusted through the combustion chamber enters a gas turbine to act through a fuel gas channel, and meanwhile the gas turbine drives the coaxial compressor to work. The slagging-preventing gas turbine combustion chamber can be widely used in the field of combustion and utilization of biomass energy such as straw.

Description

technical field

[0001] The invention relates to a combustion chamber of a gas turbine, in particular to an anti-slagging combustion chamber of a gas turbine utilizing biomass fuel. Background technique

[0002] Today, when fossil fuels such as coal, oil, and natural gas are increasingly scarce, fuel prices continue to rise, and new energy sources have become the wind vane in the energy field. A lot of research has been put into new energy sources such as solar energy, geothermal energy, and hydrogen energy. A new energy research hotspot in the 21st century, it has the characteristics of low cost, but biomass energy such as straw is basically burned directly in rural areas, causing serious air pollution and wasting a potentially important energy supply in vain. The main disadvantage of the application of straw and other biomass energy in the combustion chamber is that the slagging is serious, which is easy to block the combustion chamber, which affects its further development...
