摘要： PROBLEM TO BE SOLVED: To achieve a higher efficiency of preparation work of inspecting a boiler with a shortened blowing time by supplying a N gas to the boiler in blowing from the boiler to accomplish the blowing effectively. SOLUTION: In a blow tank device, blowing water from a boiler 1 is guided to a blow tank 4 via blowing pipes 3a and 3b having open/close valves 2a and 2b to separate air from water in the blow tank 4. The air is released into the atmospheric air from an exhaust pipe 6 while the water is drained outside the system via a drain pipe 5. In the boiler, a pressurization pipeline with an open/close valve 8 is provided to supply a pressure gas and an opening-closing means valve 7 is provided on the exhaust pipe 6 to open or close an exhaust pipeline. The opening-closing means 7 is closed during the pressurized blowing period to raise a pressure within the blow tank 4 thereby pushing out water by the pressure.

摘要： PROBLEM TO BE SOLVED: To perform combined running according to the optimum diesel engine/ boiler load sharing without exceeding the value for environmental criteria of NOx. SOLUTION: In this device, an electric generation command 21 is inputted into a function generator 23. The function generator 23 determiners a load sharing function F1 to maximize a diesel engine load sharing based on the oxygen quantity required for a boiler and the oxygen quantity in the exhaust emission of a diesel engine. Denitration inlet NOx 22 is inputted into a function generator 24. The function generator 24 generates load sharing function F2 for the diesel engine and the boiler so that boiler outlet NOx does not exceed a reference value. Both of these functions F1 and F2 are multiplied by each other to determine the optimum, and the fuel quantity 27 to be inputted in the boiler and the fuel quantity 28 to be inputted in the diesel engine are calculated.

摘要： PURPOSE: To reduce corrosion in a heat exchanging part by a method wherein a fluidized bed type seal pot is provided on the half way of a fuel charging line for supplying a chlorine-containing fuel, into a fluidized bed combustion furnace. CONSTITUTION: A fuel 8, charged through a fuel charging line 4 and containing chlorine, is reserved once in a seal pot 11 and is fluidized by a fluidizing fluid 12 together with recycle ash, charged from a fluidizing material charging line 6, whereby the temperature rises. A part of high-temperature ash, discharged out of the ash take-out port 14 of a fluidized bed combustion furnace 1 together with the fluidizing material, is reserved in the seal pot 11 whereby a temperature in the seal not 11 can be raised. In this case, the temperature in the seal pot 11 is controlled at 100-140 deg.C. According to this method, chlorine component in the fuel supplied into the fluidized bed combustion furnace 1 is reduced whereby the chlorine constituent in generated combustion gas is reduced and, accordingly, corrosion in a heat exchanging part 2 can be reduced.
