There is provided coal gasification unit including: a coal gasifier; a char recovery unit; flare equipment; an air flow rate adjustment valve and an oxygen supply flow passage that supply oxygen-containing gas to the coal gasifier; an inert gas supply flow passage that supplies nitrogen gas to an upstream side of the char recovery unit; and a control unit that controls a supply amount of the oxygen-containing gas and a supply amount of the nitrogen gas, in which the coal gasifier has a starting burner, and in which the control unit controls the supply amount of the nitrogen gas prior to starting combustion of starting fuel by the starting burner so that an oxygen concentration of mixed gas in which combustion gas generated by combustion of the oxygen-containing gas and the starting fuel has been mixed with the nitrogen gas becomes not more than an ignition concentration.

A thermal energy power device is disclosed. A gasification reactor is arranged on a TDC of a cylinder bulk of an internal combustion engine, wherein the gasification reactor includes gasifying plates (19) and gas holes (23). The gasifying plates are arranged with gaps on the TDC of the cylinder. The gas holes (23) are distributed evenly, in an array, or in a staggered manner on the gasifying plate (19). A cylinder head above the gasification reactor is provided with an atomizer (12). Heat absorption plates (26) are arranged inside the exhaust passage in parallel with an air flow direction. The heat absorption plates (26) absorb thermal energy of exhaust gas and transfer the thermal energy to the gasification reactor. The internal combustion engine is wrapped with an insulation layer. An added working stroke enables the temperature of the cylinder bulk to be lowered. The compression ratio is high.

An integrated combustion device power saving system includes: a hydrogen generation device, for generating a hydrogen-rich gas; a combustion device, for receiving the hydrogen-rich gas for combustion and generating heat energy and flue gas; a smoke distributing device, for distributing flue gas to the hydrogen generation device or atmosphere; a hydrogen-generation feed preheating device, for capturing waste heat of the flue gas from the smoke distributing device to preheat a hydrogen-generation feed to be used in the hydrogen generation device; and a power generating device, for receiving the flue gas from the hydrogen-generation feed preheating device while recycling waste heat of the flue gas to generate power to at least one of the hydrogen generation device or the combustion device.

Provided is an integrated coal gasification combined cycle equipped with: a gasifier that generates combustible gas from pulverized coal; a gas cooler; gas turbine equipment; an auxiliary fuel supply unit that supplies an auxiliary fuel to the gas turbine equipment; a heat recovery steam generator; steam turbine equipment; generators; and a circulation line unit that circulates cooling water. The heat recovery steam generator has a first medium-pressure coal economizer and a second medium-pressure coal economizer. When the combustible gas generated from the pulverized coal is burned, a serial heat exchange line is formed wherein cooling water passes through the first medium-pressure coal economizer, the second medium-pressure coal economizer, and the gas cooler. When the auxiliary fuel is burned, separate heat exchange lines are formed, wherein the cooling water separately passes through the first medium-pressure coal economizer and the second medium-pressure coal economizer.

The present invention relates to a method for producing steam, the method comprising: (a) passing waste gas through a first boiler to produce steam having a first temperature, and cooled waste gas; (b) removing contaminants from the cooled waste gas to produce clean waste gas; (c) passing the steam having a first temperature through a second boiler; and (d) burning at least a portion of the clean waste gas in the second boiler to produce steam having a second temperature, the second temperature being higher than the first temperature. The method is particularly suited to efficiently generating high temperature, high pressure steam derived from the pyrolysis/gasification of organic waste.
