The Application of Industrial Oil and Gas Fired Boiler

The application of industrial oil and gas fired boiler

This sort industrial boiler is of double drum, vertical arrangement and “D” type furnace design with a few burners located the location where the front wall stands. Within it comes with an air-tight furnace structure with densely arranged tubes and air-proof casing. Outside it truly is covered with insulation materials and convex color plates. The flue gas needs a U turn. It's going in to the 1st convection tube bank from your furnace, turns after passing the flue, and flows into the economizer with finned tubes when leaving the other convection tube bank. The water which works into your upper drum on the economizer is changed into steam by way of natural circulation after passing the convection tube bank and water cooled wall, so supplied towards the user through the main steam valve. Combustion for a slight positive pressure enables a furnace volume heat release rate as large as nearly 40×103kcal.h/m3. Lower and upper drums and convection tube banks are assembled and put through a hydrostatic test previous to delivery. The steam boiler features a capacity of 2~75t/h and dealing pressure of 0.7～5.4Mpa, even though the hot water boiler has a capacity of 0.7～21MW. The feedwater and return water temperatures are 95℃/70℃ and 115℃/70℃ respectively.

The boiler has good performance on chemical industry is horizontal gas fired boiler, this type of boiler is developed the horizontal structure and has a higher efficiency.

The boiler has got the characteristics of small volume, compact structure, high combustion efficiency, convenient installation , high penetration of automation, etc.

Adopting micro positive pressure combustion to raise the thermal efficiency minimizing the operation cost
