Product Introduction

Series of YQL gas heat conduction oil boiler adopts three return circular tube structure, by reducing coil tube department, effectively protect the end of the boiler furnace wall, equipped with advanced burner, boiler operation fully automated.After the fuel is ignited by the burner, the flame is filled in the disc tube and radiated through the wall of the tube, which is the first return journey.High temperature flue gas from the burning of convergence in the oven door, turn into the second return, namely convection bank area, the convective heat transfer, after the flue gas temperature is gradually reduced to the front door, and turned into the third return on this bundle area, then the author into the chimney into the atmosphere.

After the boiler is put in place at the site, it can be put into operation by simply connecting with gas (oil) electricity.The heating surface of the boiler consists of four parts: the radiant heating surface of the furnace, the heating surface of the first convection tube bundle, the heating surface of the second convection tube money, and the energy-saving device (waste heat boiler).

Technical Advantage

Nc 3 d laser cutting machine is adopted for steel pipe slant.
Disc control adopts CNC coil production line, one – time forming, no need to be plastic.
Automatic argon arc welding process is adopted for pipe butt joint. Meanwhile, X-ray real-time imaging is carried out for welding seams to prevent unqualified welds from entering the coil production line.
The boiler is fully assembled and manufactured for easy installation, commissioning and use.
Automatic operation, combustion, high level tank level, outlet temperature and flow are all automatically regulated and protected.
The inlet and outlet adopt two end flanges and flanged cover structure to facilitate the installation and layout of boiler room pipeline.
High quality insulation material is adopted on the inside and stainless steel plate is used on the outside to minimize heat loss and improve the operating environment.
Multi-layer tightly arranged pipe bundles and several rings of steel in each ring are used for sealing and fixing to prevent short circuit of smoke.
Residual water is removed from the factory and the system exhaust time is reduced from 12 days to 2 days.
The inner coil coil pipe has greater flow and is safer and more reliable at high temperature.
The tapered coil can effectively protect the furnace wall and top burner at the end of the boiler.
After the boiler is put in place at the site, it can be put into operation by simply connecting with gas (oil) electricity.The heating surface of the boiler consists of four parts: the radiant heating surface of the furnace, the heating surface of the first convection tube bundle, the heating surface of the second convection tube money, and the energy-saving device (waste heat boiler).
