The natural circulating fluidized bed steam boiler is a patent product belongs to Zhengzhou Zhongding Boiler Co. Ltd., established based on “Patent Law of the People’s Republic of China” by State Intellectual Property Office of P.R.China. The patent number is ZL2012 2 0333591.0
1. High thermal efficiency
The mature furnace and advanced structured separator assure the high efficiency and normal operation.
The roof of separator adopts membrane wall structure, solves the problems of air leakage, caving and damage. Improve the boiler reliability. The furnace adopts suspension type membrane water wall and anti-wear design. Water cooling furnace and membrane convection bank structure guarantee the best sealing. Adopts the structure of membrane water cooling steering smoke chamber.
Breakthrough on the structure and parametrization design on cyclone separator. The high temperature cyclone adiabatic separator adopts high efficient whole steel structure, low heat loss.
The double membrane drum walls use light type material, good sealing, and adopts the convection bank structure.
The dosage of refractory material decrease 50%, decrease the thermal inertia, sharply shorten the time of start up, pressure boost and air supply.
