Large boiler is mainly used in large-scale plants, which features high and stable vapor pressure, high working efficiency, small fuel consumption, easy operation and small repair rate.

Large boiler is mainly applied to fossil fuel power generation. The boiler is qualified to produce high-pressure and high-quality steam. With the pressurized steam, steam turbines could extract thermal energy and help to generate electricity. It features small initial investment, low requirement towards construction filed, high energy efficiency, short startup period and quick returns.
