Problems solved by technology

Therefore, the heating effect of NG is remarkable, so the mixing ratio of low-calorie gas and natural gas has to be reduced at the time of heating, and as a result, it is difficult to ensure the mixing performance of the gas
In the case of large fluctuations in its degree of difference, its effect will appear during combustion in the gas turbine, resulting in uneven combustion temperature
In the case of such unevenness, it will damage the combustor and turbine part of the gas turbine.

Abstract

A gas reforming system capable of reforming a low calorie gas into a stabilized fuel for gas turbine engines. The gas reforming system comprises a reformed gas producing unit (3) having a reaction vessel provided with a natural gas (NG) supply line (7) and an air supply line (8) and producing a reformed gas containing a hydrogen gas by mixing the NG and air and reforming the mixture gas through chemical reaction, a mixing regulator (5) for mixing a low calorie gas and the reformed gas supplied from the reformed gas producing unit (3) and supplying the mixture gas as a fuel gas to a gas turbine facility (1), reformed gas supply piping (4) for supplying the reformed gas from the reformed gas producing unit(3) to the mixing regulator (5), fuel gas supply piping (2) for supplying the fuel gas from the mixing regulator (5) to the gas turbine facility (1), and a controller (10) for controlling operations of the reformed gas producing unit (3) and the mixing regulator (5).

Description

technical field [0001] The present invention relates to gas reforming equipment, and more particularly, to the use of low-calorie (calorie) gases (such as blast furnace gas, or BFG, and gas by-products of other iron-making processes) as fuel for gas turbines, in order to enable continuous and stable combustion A gas reforming device that adjusts the gas composition of the fuel gas or the heat (calorie) of the gas by adding reformed gas to the above-mentioned low-calorie gas. Background technique [0002] Conventionally, there are more and more examples of using low-calorie gas, such as blast furnace gas (BFG) in the iron and steel industry, using gas by-products as fuel for gas turbines to generate electricity. On the other hand, the calorific value of BFG, which is process exhaust gas, is decreasing year by year due to the improvement of energy utilization efficiency in the blast furnace. When such low-calorie blast furnace gas is used as fuel, the gas turbine is prone to ...
