High Temperature Fluid Bed (HTFB) Incineration

Dispose of sludge - sustainably

As land becomes scarcer and sludge handling regulations grow more stringent, fluid bed incineration is becoming widely accepted for sludge disposal. 91大神offers thermal oxidation technologies to eliminate odors and reduce the sludge to a much smaller quantity of inert ash (as low as 7% by weight). Land requirements and air pollution are reduced, protecting the environment.

Thermal Oxidation Features

Thermal Oxidation is proven, safe and environmental friendly. Benefits include:

  • Maximum Heat Recovery –self-supporting refractory arch dome and refractory lined windbox allow maximum heat recovery and autogenous combustion.
  • Minimal Sand Loss and Optimal Combustion – teardrop-shaped reactor decelerates the combustion gas, disengaging the sand and optimizing the combustion.
  • Highly Efficient – sludge fed in the turbulent bed enhances combustion and reduces the emission of pollutants.
  • Short Startup and Low Fuel Usage – preheat burner is installed in the windbox to allow cost efficient cold starts.
  • Power Generation – heat recovery through a waste heat boiler or hot oil economizer?to generate electricity using a steam turbine or Organic Rankine Cycle (ORC).

HTFB Overview

Veolia's HTFB thermal incinerator consists of three zones: a windbox, a sand bed, and a freeboard. The term “fluid bed”refers to the violent boiling action of the sand bed, which occurs when air is blown through from below. To ensure that the air passes evenly through the sand, it must first pass through the windbox and a refractory arch distributor, where special alloy tuyeres ensure even distribution of the air. To fully take advantage of the turbulent mixing, dewatered sludge and auxiliary fuel (if required) are introduced directly into the bed, where they are instantly combusted at above 1200°F. The HTFB Incinerator can be applied in these applications:

  • municipal wastewater solids
  • pharmaceutical waste
  • chemical and paper mill waste
  • petrochemical waste
