Thermic Fluid Heaters - Solid Fuel Fired VTL 4 - Pass

Overview


SALIENT FEATURES

The vertical four pass thermic fluid heater is suited for various industries across India and abroad in this rapidly changing and undependable energy situations. Alfa Entech's generous design of vertical heaters coupled with integral furnace gives you an assurance of the rated output on any solid fuels like Coal, Wood, Lignite, Husk, Bagasse, Pet Coke, Saw dust etc without compromising on performance.
Alfa Entech can deliver sustainable solution to meet your process requirement and thus improve process consistency and reduce downtime leading to further increase in profitability.

Fluidized Bed Combustion

Fluidized Bed Combustion Technology is best suited for some of the fuels like low grade coal, paddy husk, agro waste, etc. with high ash content.


FBC Technology ensures

  • Homogeneous mixing of fuel ensuring efficient combustion due to high turbulence in bed
  • Automatic operation for consistent performance, hence less dependency on labours during continuous operation
  • Efficient Combustion of low grade fuels.

Components


The Four Pass thermic Fluid Heat Exchanger System comprises of two heat exchangers.

RADIANT HEAT EXCHANGER (FORMS FIRST PASS)

The coil of radiant heat exchanger is in conical shape and is fabricated out of high heat resistant ERW boiler tube.

  • It is mounted on suitable designed furnace.
  • It is fabricated out of heavy duty material and provided with necessary fuel feeding arrangement.
  • Furnace is constructed with high quality fire bricks and insulation bricks.
  • The bricks wall is designed in such a way that it ensures minimum heat loss.
  • The furnace also is equipped with high heat resistant casting

CONVECTIVE HEAT EXCHANGER

  • Convection zone heat exchanger is designed on coil to coil principle comprising 2 coils fabricated out of high heat resistant ERW boiler tubes.
  • Outer shell of the heat exchanger is covered with high grade insulating materials.

CONNECTING DUCT

Both radiant and convective heat exchangers are connected by a specially designed refractory duct which allows flue gas to pass from radiant to convective exchanger.
