A heat exchanger tube block is stacked on another heat exchanger tube block in an upper-lower direction and connected to the another heat exchanger tube block. The heat exchanger tube block includes: a duct casing wherein exhaust gas containing dust flows in the upper-lower direction; a heat exchanger tube in the duct casing extends horizontally; an inlet header connects to the heat exchanger tube inlet; an outlet header connected to an outlet of the heat exchanger tube; and a vibration transmitting member transmitting vibration, applied to an upper end part of the vibration transmitting member, to the heat exchanger tube to make the dust accumulating on the heat exchanger tube fall. A lower end of the duct casing is formed horizontally. The inlet header is located higher than the lower end of the duct casing. The outlet header is located higher than the lower end of the duct casing.

Heat exchanger tube block, exhaust heat recovery boiler, and method of constructing exhaust heat recovery boiler

An exhaust heat recovery boiler includes: a duct casing in which exhaust gas flows; a tubular extending portion extending upward from the duct casing; a heat exchanger tube located in the duct casing; a hammering rod connected to the heat exchanger tube in the duct casing and passing through an inside of the extending portion, the hammering rod including an upper part projecting to an outside of the extending portion; and an annular sleeve attached to the upper part of the hammering rod through a packing. The extending portion includes an upper flat surface which is located at an upper end of the extending portion, realizes a seal between the upper flat surface and a lower surface of the sleeve, and is annular and flat.

Exhaust heat recovery boiler

The present provides a waste heat boiler and a hammering device, a heating tube mounting structure thereof. The waste heat boiler which a boiler, heating tubes provided in the boiler and a hammering device; the boiler is provided with an exhaust gas inlet and an exhaust gas outlet; the heating tubes are in a horizontal grid tube arrangement; a surface of the heating tubes is provided with fins, and the heating tubes are connected to support assemblies in an unfixed way.

Waste heat boiler

To provide a power generation system that recovers heat from low-temperature exhaust gas of not more than 150&#xb0; C. and utilizes the heat to increase an amount of generated electric power of a steam turbine, whereby efficiency in thermal use can be improved. A power generation system includes heat exchangers and configured to exchange heat of a heat medium and heat of water, and a vacuum flasher configured to supply steam to a vacuum stage of a steam turbine, wherein heat media are supplied to the heat exchangers and so as to generate a water fluid having a temperature exceeding a water boiling point under vacuum of a vacuum stage, the water fluid is supplied to the vacuum flasher to generate steam under vacuum of the vacuum stage, and the steam is introduced into the vacuum stage of the steam turbine, whereby an amount of generated electric power is increased.

Power generation system

A waste heat power generation system of a cement calcination plant includes: an AQC boiler having an economizer, an evaporator and a superheater; and a PH boiler having a first evaporator and a superheater. The PH boiler, in addition to the evaporator and the superheater, has a second evaporator on a PH exhaust gas exit side, and a returned hot water from a flasher is introduced into the second evaporator via a steam drum. A hot water heated by the second evaporator is introduced into the steam drum, and a steam from the steam drum is introduced into the low-pressure stage of the steam turbine.

Direct coal fired turbine combined power generation system

The air flow rate of a fan driven by a motor controlled by an adjustable speed control equipment is automatically controlled by stopping the adjustable speed control equipment in response to a fault signal therefrom during operation with an inlet vane installed upstream of the fan in fully open state, simultaneously throttling the inlet vane at a preset speed to a degree of opening appropriate for the load by means of a control circuit, and, after a period for reduction of residual voltage of the motor, changing over to operation of the fan by a commercial power supply thereby to shift to control by the degree of opening of the inlet vane.
