YLW series coal-fired thermal fluid heater

Home / Product /YLW series coal-fired thermal fluid heater

  YLM thermal fluid heater is square coil horizontalchaingrateshop-assembledheater, chain grate and heater properare transferred separately. It adapts chain grateto realize mechanical feeding coal, mechanical venting by blower and induced draftfan, and mechanical discharging by slag machine.

  Fuel fallson thegratefrom 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 airheater, at last enters dust collector then is vented into the atmosphere through chimney by induced draftfan.

01

Digitized manufacture
  • 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.
  • Digitized manufacture

    02

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

    03

    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.
  • Long life span

    04

    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.
  • Easy operation

    05

    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.
  • Less fuel consumption
