Problems solved by technology

Moreover, in methods such as the direct reduction iron-making method, the small-capacity reactor is repeatedly started and stopped, so the amount of gas generated and the value of the calorific value fluctuate significantly, so only using N 2 Dilution is tricky

Embodiment Construction

[0161] Embodiment 1

[0162] Embodiments of the gas calorific value variation suppressing device, fuel gas supply facility, and gas turbine facility of the present invention will be described below with reference to the drawings.

[0163] FIG. 1 shows an embodiment of the fuel gas supply facility of the present invention for supplying low calorific value gas as fuel gas to a gas turbine as a combustion facility, that is, a low calorific gas supply facility 1 and a gas turbine including the low calorific gas supply facility 1. Piping diagram of the general situation of the equipment. Gas turbine equipment is represented by gas turbine power generation equipment. As mentioned above, low calorific gas means that its calorific value is about 12MJ / Nm 3 The properties of the following gases tend to change, such as calorific value.

[0164] The low calorific value gas supply facility 1 as such a fuel gas supply facility has a fuel gas supply path for supplying the by-product gas (...

Abstract

[PROBLEMS] To provide a gas calorie variation suppressor capable of supplying a low calorie gas as stabilized fuel by suppressing variation in its calorie. [MEANS FOR SOLVING PROBLEMS] The calorie variation suppressor comprises a buffer tank (10) for storing a low calorie gas temporarily arranged in a low calorie gas supply pipe (3) for supplying a low calorie gas as a fuel gas to a gas turbine (2), an inlet (10a) formed in the tank (10) and communicating with the upstream side of the low calorie gas supply pipe (3), an outlet (10b) communicating with the downstream side of the low calorie gas supply pipe (3), and an inclining pipe member formed continuously with the low calorie gas supply pipe (3) communicating with the inlet (10a) and inclining upward.

Description

technical field [0001] The present invention relates to a gas calorific value (calorie) fluctuation suppression device, fuel gas supply equipment, gas turbine equipment, and boiler equipment. More specifically, it relates to a gas calorific value fluctuation suppressing device capable of suppressing calorific value fluctuations in the case where the gas used as fuel for combustion equipment is a low calorific value gas, and a gas calorific value fluctuation suppressing device equipped with such a gas calorific value fluctuation suppressing device. The fuel gas supply facility of the device, and the gas turbine facility and boiler facility as combustion facilities equipped with the fuel gas supply facility. Background technique [0002] In the field of ironmaking, for example, when pig iron is produced by the blast furnace method, blast furnace gas (Blast Furnace Gas, hereinafter referred to as BFG) is generated from the blast furnace as a by-product gas. The total calorific...
