YLW Series Coal/Biomass Fired Thermic Fluid Heater

PERFORMANCE

YLW 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.

It's increasing heating surface and low down the height of main body and enhancing boiler overload ability.This model can get less than 320℃ under pressure of 1.0MPA.it can be used in chemicals, light industries construction materials food processing, packing equipment, plastic industry and rubber industries and so on.

Advantage:

1. High thermal efficiency

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

2) The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

3) Equipped with economizer, make full use of flue gas heat, decrease the exhaust smoke temperature.

2. Large combustion chamber

1) The boiler combustion chamber is composed with chain grate and large diameter coil, large combustion space, high combustion efficiency.

2) Combustion equipment and boiler upper part are designed separately, the boiler combustion chamber could be designed based on the characteristics of different fuels, wide adaptability of different fuels.

3. Excellent coil design

The radiation section adopts square coil, and the convection section adopts serpentine coil, the heating coil has a good thermal expansibility, low stress, safe and reliable.

4. Automatic chain grate

1) The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.

2) The chain grate has a low coal leakage because of the small gap.

3) Convenient for maintenance, it could be done without boiler shut down.

4) Based on customers’ requirement and fuel characteristics, the grate could be designed as small scale grate, chain belt grate, and bar grate, etc.

5. Sufficient output

The boiler adopts horizontal type three pass structure, improve the heat utilization efficiency. Large heating area, good heat transfer, achieve high thermal efficiency and sufficient output.
