airflow on cyclone separator boiler cfb

Currently the design of water tube airflow on cyclone separator boiler cfb configuration, there are four, namely, D, A-type, O-type and angle tube. Four structural types of the most popular type D, since D-type arrangement is more flexible in terms of superheater and economizer, the boiler can save a lot of building area.

Combustion ratio adjustment technique: Boiler intelligent controller with proportional control valve to the natural gas composition and the premix fan inverter, to ensure optimum air-fuel ratio, and automatically adjusts the airflow on cyclone separator boiler cfb output to meet the dynamic heat load, the heat output curve as close to the dynamic heat boiler the demand curve, fewer invalid output, has reached the lowest emission effect. Combustion ratio adjusted in the range of 10% -100%.

Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green airflow on cyclone separator boiler cfb heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.

Reheater is essentially a low-pressure steam has done work again heated and reaches a certain temperature steam superheater, reheater effect of further improving the thermal efficiency of the cycle plant, the steam temperature control and last stage steam turbine blades within the allowable range. The steam superheater from the steam turbine in the airflow on cyclone separator boiler cfb is heated up to a superheated steam heater. The main effect of heat and then there are two, one is to reduce the humidity of water vapor, help to protect the turbine blade; the second is restrained to increase the relative rate and absolute turbine internal efficiency. Heated again by the high pressure exhaust cylinder is returned to the boiler steam turbine, and then to the low pressure cylinder expansion work. Purpose is to make the steam turbine last stage blades and humidity controlled within the allowable range. Reheat steam pressure of 20% superheated steam pressure. More than 125MW Unit in China have adopted the single reheat system.
