摘要： A heat recovery boiler has a casing, a superheater having a heat transfer pipe, an evaporator provided with a steam drum, and an economizer. The superheater, evaporator and economizer arranged in the casing along a flow of an exhaust gas from the combustion system. A lead pipe connects an inlet of the pipe line to the steam drum while a superheated steam pipe line connects an outlet of the pipe line to the steam drum of the evaporator. A drain pipe is connected to the pipe line while a superheater bypass pipe having a superheater bypass valve has a first end operatively connected to the steam drum and a second end connected to the superheated steam pipe. With this arrangement, the superheater bypass valve incorporated into the superheater bypass pipe and a drain valve in the drain pipe are opened. Force is applied to water collected in the bottom of the superheater by passing saturated steam generated from the steam drum through the lead pipe and the superheater bypass pipe. Drain water is blown out of the system through the drain valve.

摘要： An amount of energy consumption in a semiconductor fabrication facility can be reduced by using cooling water drained from a semiconductor fabrication apparatus as a heat source of another semiconductor fabrication apparatus. Cooling water of 80° C. drained from a heating furnace of a heat processing apparatus (10) is supplied to a deionized water heating apparatus (32) of a cleaning apparatus (30). The deionized water heating apparatus (32) raises a temperature of deionized water of a room temperature to 60° C. through heat exchange with the cooling water of 80° C. The cooling water, whose temperature falls to 30° C. after the heat exchange, is reutilized for cooling of the heating furnace (12).

摘要： Combustion method and apparatus for NOx reduction which are capable of achieving NOx reduction with the value of exhaust NOx under 10 ppm, as well as CO reduction at the same time. The combustion method for fulfilling NOx reduction and CO reduction by suppressing temperature of combustion gas derived from a burner comprises a NOx reduction step for suppressing combustion gas temperature in such a manner that suppression of NOx generation is preferred to reduction of exhaust CO value, thereby keeping NOx value not more than a specified value, and a CO reduction step for thereafter reducing exhaust CO value resulting from the NOx reduction step to not more than a specified value.

摘要： A heat recovery system includes a heat exchanger surrounding a flue pipe from a furnace for preheating water. The heat exchanger includes a sleeve surrounding the flue pipe to define an annular space and form a water jacket in direct contact with the flue pipe. Several water storage tanks are connected in series and mounted around the sleeve to absorb heat from the water jacket. The outer water tanks are connected to one end of the water jacket at the downstream end of the flue pipe so that water is carried sequentially through each of the water tanks and through the water jacket surrounding the flue pipe. Typically, the water jacket includes a plurality of baffles to define a tortuous path through the water jacket. A conduit for supplying water to the outer water tanks can be wrapped around the downstream end of the flue pipe in a spiral manner to preheat the water prior to feeding to the water tanks. The preheated water exiting the upstream end of the water jacket can also pass through a conduit that is wrapped around the flue pipe in a spiral fashion to further heat the water before directing to a conventional water heater or domestic water supply.
