摘要： A boiler sequencer system having a microprocessor based controller which allows the firing rate for multiple boilers to be increased or decreased with a proportional output integrated with the process variable rate of recovery that is desired, preventing unnecessary rapid advancements to high fire even when a boiler is started with a high off-set of the process variable from its set point. The controller automatically overrides this proportionate control when the process variable rises above a predetermined maximum or falls below a predetermined minimum.

摘要： An apparatus for controlling a starting operation of a boiler comprising a super heater (5), a super heater bypass valve (9), a turbine bypass valve (10) and a fuel flow rate regulating valve (20). A temperature detector (25) detects a temperature of the steam at a predetermined portion of the boiler. A pressure detector (11) detect a pressure of the steam at the predetermined portion of the boiler. A desired change rate arithmetic unit (30) calculates a desired steam temperature change rate value and a desired steam pressure change rate value on the basis of the steam pressure, the steam temperature, a desired pressure increase value, a desired temperature increase value, a saturated temperature change rate limit and a temperature increase change rate limit. An optimum operation arithmetic unit (40) calculates opening degrees of the super heater bypassing valve (9), the turbine bypass bypass valve (10) and the fuel flow rate regulating valve (20), respectively, on the basis of the steam temperature, the steam pressure, the desired steam pressure change rate value and the desired steam temperature change rate value obtained by the desired change rate arithmetic unit (30). A compensation arithmetic unit (60) compensates for the respective opening degrees obtained by the optimum operation arithmetic unit (40), on the basis of the change rates of the steam temperature and pressure.

摘要： A master controller (MC) receives a load demand and a plurality of plant data from a heat power plant and outputs command signals on at least two of an electric power, a feed water flow rate, a fuel flow rate, an air flow rate and a recirculation gas flow rate of the plant required to achieve the load demand. A plurality of sub-loop controllers (SLC) independently provided one for each of the command signals provide control quantities for controlling respective control ends in accordance with the command signals. A transmission loop is arranged between the sub-loop control- lera and the master controller. Drive means (40) drive the control terminals provided one for each of the control quantities supplied from the sub-loop controllers. An I/O bus (80) is arranged between one of the sub-loop controllers and the drive means driven by the command signal for the one sub-loop controller. Detection means detect the plant data to be delivered to the master controller or the sub-loop controllers.

摘要： Thermal stress of a metal portion of a pressure-tight tube is calculated on the basis of calculated values of a temperature distribution calculator for calculating the distribution of temperature at positions equidistantly arranged in a direction of the thickness of the aforesaid tube on the basis of measured values of metal portion of the aforesaid tube, whereby the thermal stress being changed momently is accurately measured and monitored. Further, there is provided a calculation cycle for presetting calculation cycles on the basis of measured values of the fluid temperature in the aforesaid tube. The calculation cycles are made short when fluctuations in the measured values of the fluid temperature are large, while, the calculation cycles are made long when fluctuations in the measured values of the fluid temperature are small.

摘要： A method for maximizing thermal efficiency of a power plant, the method comprising obtaining the current state of the plant from available measured data; obtaining a set of Variables representing a current state of the power plant; applying a set of constraints to the Variables; generating a revised set of Variables representing a revised state of the power plant; and testing the revised set of Variables within a mathematical model for convergence. Generating the revised set of Variable is based at least partly on: Euler's equation, the conservation of mass equation, and a mathematical description of a reversible continuum.

摘要： Method and system for adjusting a measured reheat outlet steam temperature ("R PV ") to approximate a reheat outlet steam temperature setpoint ("R SP ") in a boiler. An R PV is compared to an R SP . If the R PV is less than the R SP and a position of a fuel nozzle tilt ("TILT PV ") is below a high limit of the fuel nozzle tilt ("TILT HIGH "), the TILT PV is increased while a flow rate of a secondary flue gas recirculation ("SFGR PV ") is kept constant. If the R PV is less than the R SP and the TILT PV is at the TILT HIGH , the SFGR PV is increased. If the R PV is greater than the R SP and the SFGR PV is greater than a low limit of flow rate of the SFGR ("SFGR LOW "), the SFGR PV is decreased, while the TILT PV is kept constant. If the R PV is greater than the R SP and the SFGR PV is at the SFGR LOW , the TILT PV is decreased.
