Utility Steam Generators / Boiler Technology
Highly Efficient Utility Steam Generators
With its thousands of welds, pipes extending several hundred kilometers and many thousands of tons of heavy structural steel, the utility steam generator (boiler) is at the heart of any fossil-fired power plant. This is where the pulverized fuel is burnt at around 1,450 °C; forming here are also the hot flue gases and the extremely hot steam under high pressure, which subsequently drives the turbine blades.
Mitsubishi Hitachi Power Systems Europe develops, designs and supplies steam generators for unit capacities up to and over 1,100 MWe with 300 bar plus pressures, 600 °C live steam temperatures and reheater temperatures up to 620 °C for all the available fossil fuels. These extend from coal and lignite to specific fuels (e.g. gases from coke ovens / steelworks and refinery residues).
With a track record extending back over 100 years, Mitsubishi Hitachi Power Systems Europe is one of the market and technology leaders in utility steam generators. References include over 370,000 MW of installed power plant capacity (of which 180,000 MW is coal, 43,000 MW lignite and 140,000 MW oil and gas firing) which have been set up since 1970.
Developments are constantly ongoing in utility steam generators. New, highly-resistant materials, for instance, should enable them to achieve even higher steam temperatures and pressures. This is the way to raise the efficiency of tomorrow's coal power plants to over 50%.
Extensive know-how in boiler technology
Across the world our boiler technology service specialists attend to plants with varying fuel requirements and steam throughputs of 20 up to 2,200 t/h. Moreover, they prepare tailored solution concepts for plants with:
- Natural circulation boilers (water tube boilers)
- Once-through boilers (Benson and Sulzer boilers)
- Heat recovery boilers
- Waste incineration systems
- Fluidized bed systems
- Special boilers (e.g. in the chemical industry)
The range of work & services includes rehabilitation of entire plants or individual components, operating efficiency optimization, increasing availability rates, emission reduction and service life extension steps and adjustments undertaken during firing change-overs. All this is is backed up by our expertise in heat recovery optimization in the chemical industry, in re-powering and in combined cycle plant retrofitting via upstream use of gas turbine.
