Brief introduction to features of full-automatic oil & gas boilers
    
  1. All its products are produced in the form of speedy assembly. The main engine, electric controller, meters and pipelines inside the boiler are installed together. When they are transported to the working site for installation, it will be good to connect the resources of oil, electricity and water and pull out the steam pipes.
  2. Its product have enough heated area and strong overloading capability. Equipped with "wet-back" structure, the boiler body has been improved greatly in heat efficiency, generally 5% above the regulated of Ministry of Mechanic Industry.
  3. Using the imported famous-brand engine has improved the stability of combustion in operation.
  4. With the full-automatic controlling function, it is installed with imported elements. And it adopts the multilevel protection in the water supply of boiler so as to guarantee the safety and stability of operation.
  5. The phosphate anti-fire bricks and aluminum silicate are used as the heat insulation and thermal insulation materials so as to effectively lower the loss of heat. The face temperature for the outer covering of boiler is not more than 50℃.
  6. Small in volume, small in land area and low in pollution level, it can have users gain the maximum benefits with minimum investment.

Brief introduction to flow of smoke and steam
    

The horizontal series oil boiler designed by our works is equipped with the "wet-back" structure. After the oil is heated, it will be sprayed into the chamber of boiler for combustion through the atomized spray nozzle of the combustion engine. The chamber of boiler is mainly made of wave boiler liner which can bear the flexibility of boiler arising out of expansion with heat and contraction with cold. When the high-temperature smoke and steam rush to the end of the chamber, they will return the thread pipe of the 2nd return trip through the return-combustion box. Much due to the data coming from the thread pitch and ditch depth, it can effectively improve the movement of smoke and steam in the pipe and play the role of intensifying heat passage. When the smoke and steam reach the front of the boiler, they will enter the pipe of the 3rd return trip through the front smoke box. They will be discharged into the airspace through the chimney after the final washing and heat generating.
