YLW series coal-fired thermal fluid heater

YLM thermal fluid heater is square coil horizontal chain grate shop-assembled heater, chain grate and heater proper are transferred separately. It adapts chain grate to realize mechanical feeding coal, mechanical venting by blower and induced draft fan, and mechanical discharging by slag machine.

Fuel falls on the grate from coal bucket during operating and burning, high temperature smoke enters furnace by passing combustion arch, after radiation heat exchange, smoke enters convection heating surface for convection heat exchange, then goes to waste heat boiler and air heater, at last enters dust collector then is vented into the atmosphere through chimney by induced draft fan.

1 . The laying-off of steel tube adopts CNC 3D laser cutting machine.

2 . Square coil tube and coil tube all adopt argon arc welding technique,which guarantees tubes are 100% qualified.

3 . The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;

4 . We have combustion arch patent, which is available for different types of coals, even the anthracite is very easy to burn.

Technical advantages

5 . The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.

6 . Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

7 . There is ash cleaning unit, which is easy for maintaining, operating and cleaning.

8 . 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.
