Equipment and method for preparing fuel gas for power generation

Abstract

The invention provides equipment and a method for preparing a fuel gas for power generation. The equipment comprises a furnace body, wherein a tower type synchronous roller extruder of a circular stepped groove mould plate is arranged at the upper end of the furnace body; the tower type synchronous roller extruder is equipped with a material containing barrel; the material containing barrel is in airtight connection with the furnace body; a first transmission shaft is arranged in the material containing barrel; two tower type synchronous rollers are at least arranged on the first transmission shaft, and are symmetrically distributed at the two sides of the first transmission shaft; in the material containing barrel, the circular stepped groove mould plate is arranged below the tower type synchronous rollers; a feeding hole is formed in the upper end of the material containing barrel and an opening is formed in the lower end of the material containing barrel; the opening is positioned in a fuel gas generating furnace; a furnace grate is arranged on the lower part of the furnace body of the fuel gas generating furnace; the furnace grate is connected with a second transmission shaft; a power transmission piece is arranged on the second transmission shaft; the power transmission piece is connected with a motor; an ash separating plate is arranged on the middle upper part of the second transmission shaft; the furnace grate is formed by connecting a plurality of layers of circular plates from top to bottom, and the diameters of the circular plates are gradually increased from top to bottom. The equipment and the method disclosed by the invention can be used for solving the defects in the prior art.

Description

technical field [0001] The invention relates to gas preparation, and relates to equipment for preparing gas for power generation and a method for preparing gas. Background technique [0002] The gas used in gas turbine power generation requires technical indicators such as high calorific value and high purity, otherwise, the gas turbine cannot continue to operate normally. To make coal gas reach the above-mentioned technical indicators, the fuel used for preparing gas must be refined lump coal, coke or high-quality pulverized coal, coal-water slurry or fuel oil suitable for spraying. However, these raw material resources are limited, and the cost of gas used for preparation is extremely high, which cannot maintain the normal operation of the gas turbine, resulting in almost a standstill of coal gas turbine power generation. In order to reduce the cost of gas turbine power generation, those skilled in the art have adopted pressurized water gas, dry gas, and spraying pure spe...

Problems solved by technology

However, these raw material resources are limited, and the cost of the gas used for preparation is extremely high, which cannot maintain the normal operation of the gas turbine, resulting in the fact that the power generation with coal gas turbines is almost at a standstill

In order to reduce the cost of gas turbine power generation, those skilled in the art have adopted pressurized water gas, dry gas, and spraying pure special pulverized coal gas to supply gas turbines, but these methods still cannot meet the requirements of reducing the power generation cost of gas turbines.
