Abstract

PURPOSE:To enhance the safety of a system by sending both steam and heated water, which are obtained at different heat exchanging areas in an exhaust duct, in which gas turbine exhaust gas goes through, to a reactor which decomposes methanol by heating. CONSTITUTION:Gas turbine exhaust gas goes through a single exhaust duct 20. The inside of the exhaust duct 20 is divided into different heat exchanging areas, and feed-water 33 is forced to pass through the respective areas. Steam 37, which is generated in a super high pressure evaporator 24, heated water 38 coming out of the outlet of a secondary fuel economiser 28, and heated water 39 coming out of the outlet of a primary fuel economiser 30 are sent to a reactor 36. In the reactor 36, methanol is decomposed by heating, and the decomposed gas 40 is sent to a gas turbine combustor. With this contrivance, since methanol is not directly exposed to exhaust gas, the safety of the system can be enhanced.

なシ、安全性が向上する。Effects of the Invention As detailed above, according to the present invention, in thermally decomposing methanol, a so-called indirect heat exchange method using steam and hot water as a heating medium is adopted, so that methanol is not directly exposed to exhaust gas. There is no risk of fire or the like being caused by the accident, and safety is improved.

また、排気ダクトとメタノール反応器とを分離すること

調整の困難さを解消することができる。Moreover, according to the present invention, the exhaust duct is changed from the conventional branch duct system to a series duct system, so there are the following advantages. In other words, in the direct heat exchange method, it was necessary to use a branch duct to separate the methanol reactor and the steam supply system of the steam turbine, considering the risk of methanol leakage and the startup time. In the heat exchange method, since the methanol reactor is located outside the exhaust duct, there is no necessity to separate the heat supply system for methanol from the steam supply system for the steam turbine. Therefore, in the case of the indirect heat exchange system, it is possible to use the series duct system to eliminate the complexity of the boiler structure, the gas amount of each duct, and the difficulty in adjusting draft loss caused by the branch duct system.

効率が得られる。Further, according to the present invention, efficiency can be improved by supplying heat to methanol in multiple stages. To explain in detail, the fact that the total amount of heat required for the methanol reaction is supplied only by the heat obtained at the high exhaust gas temperature level is because the methanol reactor inlet temperature is at room temperature.
In addition, it cannot be said that this is the optimal heat supply method because the amount of heat absorbed by the high-pressure system is reduced and the amount of evaporation is also reduced, and heat should be supplied by a heat source that matches the temperature of each stage of methanol. That is, the heat obtained in the high temperature range of exhaust gas should be supplied to the high temperature range of methanol, and the heat obtained in the low temperature range of exhaust gas should be supplied to the low temperature range of methanol. In this regard, according to the present invention, the steam and hot water obtained in different heat exchange zones in the exhaust duct are sent to the reactor to heat the methanol, so efficiency can be improved and the blunt In terms of generating end efficiency, the efficiency is almost comparable to that of the direct heat exchange method.
