Gas/Oil Fired Condensing Boiler is a packaged water tube boiler with double drums and D-type layout. It has lots of advantages such as sufficient burning, no pollution in the emission, convenient operation, easy installation etc. Besides, Condensing boiler have the features such as high thermal efficiency, high output, better load adaptability, and high automation level as well as safe and reliable operation. It is an ideal environmental protection product with high efficiency, low energy consumption and less pollution which will play an important role in the application field of thermal energy equipment in future.

• The key processing technology like material preparation of steel tubes, circling, drilling of tube plate, etc are all adpot advanced CNC machining process to decrease the assemble stress and extend the boiler working life
• Interior thermal insulation is adopted to flue gas duct and flue gas port to reduce the noise during the boiler operation
• All convection tubes of high temperature area use vibrating proof fastener to provent the pipe orifice of convection tubes from fracturing
• The inside of observation hole uses moulding high-alumina refractory and manhole cover sealing device to solve the problem of overheating of this part by constructed with refr actory bricks
• Every piece of membrane wall between furnace and convection tubes use high temperature resistance stainless steel Cr25ni20. This avoid the breakdown of high temperature flue gas short circuit caused by using refractory materia
• Impeller blasting and stoving varnish are done to boiler to make sure the boiler has good-looing appearance and anti-septic property

• The boiler vertical and circular seam adopts advanced unionmelt welding process to ensure the welding quality.All the vertical and circular seams will be done 100% radiographic inspection.
