Tiszaújváros Heating plant

The construction of connected heat-electricityproducing heating power plant, to supply with thermalenergy the heating system of Tiszaújvaros.

Content:

The full range of designing, constructing,commissioning and operating of the heatingplant.

Description:

The heating plant dispose of 42,8 MW thermal output due to its 2 pieces of 3,4 MW thermal power gas engines, and 3pieces of 12 MW thermal power boiler. It dispose of 6,4 MW electrical power due to the 3,2 MW gas engines. Theutilization of the produced heat is done by heating of district heating water. Connection of the gas engines can be linearwith the boilers, or can be independent from them. The continuous electrical power generation are assured by the forcecoolers equipped with noise absorbing wall in the operation without heat-removal. The gas engine rooms are separatedand noise insulated, which dispose of its own operating an emergency ventilation system. The exhaust gas system of thegas engines has rapture discs, for the protection against overpressure. The heating plant has equipment for the districtwater and boiler feed make up, which were mounted in the boiler room.
