Description
YQW 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.
Technical advantages
1. Square coil pipe and coil pipe all adopt argon arc welding technique and the weld line will be done 100% radiographic inspection.
2. Fully automatic operating, burning, high slot oil level, output temperature and flow rate are adjusted automatically and self-protected.
3. Before delivery, the residue moisture is removed completely, so the system draining period is reduced to 2 days from 12 days.
