摘要： PROBLEM TO BE SOLVED: To prevent the high-temperature corrosion of a waste heat boiler superheater by providing a high-temperature corrosion prevention control means for estimating the heat exchanger tube temperature of the waste heat boiler superheater during additional start of a unit, and correcting the steam pressure controlled by a turbine bypass valve opening according to the estimated heat exchanger tube temperature. SOLUTION: A refuse incinerating power plant 100 for guiding the steam from waste heat boilers 5a, 5b to a steam turbine 6 to generate a power is provided with a high-temperature corrosion prevention control means 200. The high-temperature corrosion preventing control means 200 is formed of a heat exchanger tube temperature estimating means 210 and a steam pressure correcting means 220, the heat exchanger tube temperature estimating means 210 estimates the heat exchanger tube temperature of a waste heat boiler superheater during additional start of a unit, and the steam pressure correcting means 220 outputs a correction signal for correcting the steam pressure controlled by turbine bypass valve opening according to the heat exchanger tube temperature. Namely, the heat exchanger tube temperature estimating means 210 works as a heat transfer dynamic characteristic model for estimating the heat exchanger tube temperature of the waste heat boiler superheater.

摘要： PROBLEM TO BE SOLVED: To improve the controllability when the calorific power of fuel is changed by inputting a correcting layer temperature command from a layer steam temperature controlling master, integrating it at low velocity and arranging a multiplier multiplying the integrated layer height correcting signal with a layer height command from a layer height program. SOLUTION: Temperature 51 detected by a steam temperature detector 35 is input to a water-fuel ratio control master 49 and a layer temperature steam temperature control master 66 having bean input with set up steam temperature 50 in the operation of a boiler. A correcting layer temperature command 69 from the layer temperature steam temperature control master 66 is input to a low speed integrator 87 and integrated at low speed. An integrated layer height-correcting signal 88 from the low speed integrator 87 is multiplied with a layer height command 44 from a layer height program 43 through a multiplier 89. Therefore, the discrepancy between the layer height command 44 of the layer height program 43 and the optimum value of the planned value base is corrected at slow speed. Therefore, the static characteristic of the layer height command 44 is corrected to the optimum value of the planned value base.

摘要： PURPOSE: To control a fluctuation rate so as not to damage a turbine by suppressing an inner pressure of the heater to be a specified value or lower, keeping a heating steam inflow rate constant, and then fully closing the heating steam valve so as to obtain a steam temperature reduction rate at the heater outlet within a specified range by means of a control means. CONSTITUTION: In order to separate a moisture remover 5, drain in drain tanks 9 to 11 for a heater is discharged to a condenser 16. Heated steam is supplied to the heater at the discharge time of the drain, so that drain flush is prevented due to high pressure in the heater. When the drain tank is vacant, the inner pressure in the heater is abruptly lowered. The heating steam rate flowed into the heaters 6 to 8 is increased, for increasing the steam velocity in the piping and damaging the equipment. By controlling openings of heating steam valves 20, 21, the heating steam flow rate is suppressed to be a specified value or lower, for suppressing damage of the equipment. The steam temperature of the heater is lowered within the range of the fluctuation ratio so as not to damage the turbine, so that the turbine is not damaged.

摘要： PURPOSE:To make smaller the heating surface area of a reheater which is disposed in a waste heat recovery heat exchanger and reheats steam by using exhaust gas from a gas turbine and to control the temperature of steam introduced into an intermediate and low pressure turbine to a predetermined temperature without controlling the temperature of steam delivered from the reheater. CONSTITUTION:By such a design that exhaust gas 38 from a gas turbine 28 can be fed into a waste heat recovery heat exchanger 33 including a reheater 31, the steam from the reheater 31 can be introduced into the inlet port of a secondary reheater 7b in a boiler body 3, and the flow of steam 11 fed to the reheater 31 is controlled by a control valve 34, temperature of steam 14 delivered from the secondary reheater 7b is controlled.
