摘要： PROBLEM TO BE SOLVED: To minimize damage to the moving and stationary blades of a turbine caused by scattering of inner structure inside of a turbine casing, and to enhance power generation output of the gas turbine in the summer season with compara tively low modification cost. SOLUTION: Gas turbine power generating equipment 1 is provided with an air compressor 2 which compresses air, a gas compressor 3 which pressures gas up, a combustor 4 which feeds the compressed air compressed by the air compressor 2 and the fuel gas pressured up by the gas compressor 3 and combusts, a gas turbine 5 which is driven by energy of the fuel gas from the combustor 4 and drives a generator 6, and a moisture injection means 7 which injects moisture into the fuel gas pressured up by the gas compressor 3.

摘要： PROBLEM TO BE SOLVED: To operate a furnace top pressure power generation facility in a state of high efficiency by enabling electricity to be generated by a turbine so as to be maximum and steady in output without sharply reconstructing an existing facility. SOLUTION: A control device 400 is provided with a water spray control means 401 and a combustion air quantity control means 402, when the temperature of BFG at an turbine inlet, obtained by a temperature meter 301 exceeds an upper limit value set in advance, or when the output value of a turbine obtained by a generator 500 exceeds an upper limit value set in advance, the water spray control means 401 allows a closing valve 304 to be opened so as to let water be sprayed to BFG flowing in the inside of a by-product gas flowing pipe 3 out of a mist spray device 100. In order to secure the temperature of BFG at the inlet of a turbine 2 so as to allow the output value of the turbine to be obtained by the generator, to be maximum and constant within the capacity of its facility, the combustion air quantity control means 402 controls a flow rate control valve 305 in such a way that combustion air at a flow rate corresponding to the temperature, is blown in the inside of the by-product gas flowing pipe 3.

摘要： PROBLEM TO BE SOLVED: To provide a pilot burner to the combustor of which carbide (soot) is hard to stick, a heating apparatus using the pilot burner and a power- generating unit incorporating the heating apparatus therein. SOLUTION: A pilot burner 13 has a double-tubular structure of an inner cylinder 20 and an outer cylinder 21, wherein the interior of the inner cylinder 20 serves as a gas supply path 29 and a space between the inner and outer cylinders 20 and 21 serves as an air supply path 28. The pilot burner 13 further comprises a plurality of jet nozzles 23 at the downstream-side end of the inner cylinder 20, and a flame-stabilizing baffle 22 having openings for passing combustion air therethrough, which baffle is arranged at the upstream-side of the jet nozzles 23 such that it intercept the air supply path 28 to form a combustor 26 in the outer cylinder 21 downstream of the flame-stabilizing baffle 22. The openings for passing combustion air are a plurality of small holes formed over the entire surface of the flame-stabilizing baffle 22.
