YQ(Y)L series gas-fired/oil-fired thermal fluid heater

YQL series gas-fired thermal oil boilers 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.

Long life span

The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

Easy operation

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.

Less fuel consumption

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.Furnace adopts double close line coil, which makes heating surface sufficient.
