Gas fired thermal oil heaters have a three-pass round coil structure. A conical coil is used for the effective protection of the furnace wall at the boiler end. This product is equipped with an advanced combustion device and is fully automated in operation. After the burner ignites the fuel, flame fills the round coil tubes and transfers heat by radiation through the tube wall (first pass). The high temperature flue gas gathers at the back door and then turns to the convection tubes section (second pass), where heat transfer takes place by convection. The flue gas gradually cools down here and flows to the front door, where it is reversed and goes into the third pass. After that, it enters into the chimney through the economizer and is released into the atmosphere.
The laying-off of steel tube adopts CNC 3D laser cutting machine.
The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.
Square coil tube and coil tube all adopt argon arc welding technique,which guarantees tubes are 100% qualified.
The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life.
Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.
We have combustion arch patent, which is available for different types of coals, even the anthracite is very easy to burn.
Flame-proof feeding bucket can avoid the feeding bucket is burnt and coking.
There is ash cleaning unit, which is easy for maintaining, operating and cleaning.
Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50℃ to make the minimization of loss.
The key processes including material cutting, rolling, drilling are done by advanced CNC machining process to reduce the assembly stress and extend boiler service lifetime.
Furnace adopts double close line coil, which makes heating surface sufficient.
