The New Product Bidragon Pulverized Coal Fired Boiler
1. Brief Introduction of Pulverized Coal Fired Boiler
A pulverized coal fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.
The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels. Coal is ground to the size of a fine grain, mixed with air and burned in the flue gas flow. Biomass and other materials can also be added to the mixture. Coal contains mineral matter which is converted to ash during combustion. The ash is removed as bottom ash and fly ash. The bottom ash is removed at the furnace bottom.
This type of boiler dominates the electric power industry, providing steam to drive large turbines. Pulverized coal provides the thermal energy which produces about 50% of the world's electric supply.
2. Feature of Bidragon Pulverized Coal Fired Boiler
Based on the advanced pulverized coal fired technology, include the technology of pulverized coal feed, storage, transportation, combustion, ignition, flue gas cleaning, automatic control. Bidragon company provide a whole set of new type industrial boiler technology for customer.
Adopting Pulverized coal concentrated preparation, precision pulverized coal making technology, fractional combustion, in-furnace desulphurization, shell type ( water tube) heat exchanger, high efficient bag house dust collector, flue gas desulphurization and high intelligent automatic control system, Bidragon realized the high efficient and clean emission target of industrial pulverize coal boiler.
3. Advantage of Bidragon Pulverized Coal Fired Boiler
High efficiency and energy saving: burning rate of pulverized coal is beyond 98%, heating rate is beyond 88%,saving 35%-50% coal than the traditional coal fired boiler. Installing frequency converter on big power electric equipment saved much electric power obviously. Exhaust gas temperature is not more than 150°C.
High intelligent PLC or DCS control system: equipped with automatically control technology, boiler running, coal transporting, desulfurization dust removing, etc. is all controlled automatically, which ensures less smoker and better working environment. The system realizes instant start-stop function, cutting off the ignition source for 30 seconds and then run normally. Cutting off feed makes boiler stop. Automatic monitoring and parameter adjusting keeps it best running condition, meanwhile which decreases labor strength and disturb to boiler brought by human factor.
