YQL series gas and oil-fired thermal fluid heater adopts 3-trips round coil tube structure. The coil tube end adopts beam port to effectively protect the furnace all at boiler end, is equipped with advanced combustion device, and with fully automatic operation. After furl ignition from burner, it forms a flame full fill into the round furnace tube, and through the furnace tube wall, the heat is transferred by radiation, which is the first pass. The high temperature flue gas after combustion gathers at rear furnace door and then turns into the second trip, which is convection tube area. After convection heat exchange, the flue gas temperature is going lower and comes to front furnace door, and from here it turns into the third trip ether into the tube bundle area, then through economizer its emitted into atmosphere through chimney.
This type of heater is delivered in one whole body, and after erection at site, it only needs to connect thermal gas(oil) piping and electricity to start operation. The heater has 4 heating areas: furnace radiation heating area, the first convection tube heating area, the second convection tube heating area and economizer (waste heat boiler)
Heater is wholly assembled and delivery, it is easy for installation, commission and operating.
Fully automatic operating, burning, high slot oil level, output temperature and flow rate are adjusted automatically and self-protected.
Less fuel consumption
External side adopts good insulation material, outside use stainless steel plate, which can mostly reduce heat lost, make working environment better.
Multilayers solid matter tube bundle and steel rod is used to seal and fix completely eradicate flue gas short circuit.
Before delivery, the residue moisture is removed completely, so the system draining period is reduced to 2 days from 12 days
The inner coil pipe has bigger flow amount, so it is more stable under high temperature operation.
Conical coil, effectively protects the furnace wall at the end of heater and burner on top.
