A control system is configured to control a temperature of a fuel which is supplied to a combustor of a gas turbine via a fuel gas heater, which is configured to heat the fuel of the gas turbine, by adjusting a flow rate of heated water which is supplied to the fuel gas heater. The control system includes a water flow rate adjusting unit configured to adjust the flow rate of the heated water which is supplied to the fuel gas heater based on a difference between a target temperature of the fuel and the temperature of the fuel on an outlet side of the fuel gas heater.

The disclosed concept presents a combination of a gas-turbine power-plant and a pneumatic motor, acting as an isobaric motor-combustor for the gas-turbine power-plant, to the end of achievement of a highly efficient generation of energy/power. In the process of isobaric combustion of fuel within the pneumatic motor, the pneumatic motor, which is supplied with compressed air by an air compressor from the gas-turbine power-plant, simultaneously performs mechanical work of isobaric combustion (in addition to the mechanical work of adiabatic expansion of the gas turbine) and thus increases the overall cycle output and the cycle thermal efficiency. Various combinations between gas-turbine power-plant and pneumatic motor are disclosed: simple, simple-recuperated, intercooled and intercooled-recuperated gas-turbine-cycle configurations, as well as simple and intercooled combined gas-turbine-steam-turbine cycle configurations.

Systems, apparatus, and methods described herein can overcome some of the disadvantages associated with existing internal combustion engines. In particular, systems, apparatus, and methods described herein relate to improving the combustion process of internal combustion engines through insert technologies, engine modifications, control technologies, and/or other methodologies.

The purpose of the present invention is to provide a furnace wall in which a throat section with a smaller channel diameter than other regions can be formed using all peripheral wall tubes. Provided is a furnace wall comprising: a plurality of peripheral wall tubes (142), which are disposed so as to form a cylindrical shape when aligned in one direction and through the interior of which cooling water flows; and fins (140) that connect neighboring peripheral wall tubes (142) in an airtight manner. In a throat section in which the diameter of a horizontal cross-section of the cylindrical shape is reduced in comparison to other regions, the peripheral wall tubes (142) are disposed so as to be in mutual contact and the fins (140) are disposed on the inner circumferential sides of the cylindrical shapes.
