SCHACK® AIR PREHEATER

SOPHISTICATED SOLUTIONS FOR PROLONGED LIFETIMES.

SCHACK® Air Preheaters are our process-optimized heat transfer solutions for sludge incineration, carbon black plants and gasification.


In fuel-fired industrial heating processes, one of the most effective ways to improve efficiency and productivity is to preheat the combustion air which reaches the burners.

The source of this thermal energy is the exhaust gas flow exiting the process at increased temperatures.
A heat exchanger located in the exhaust duct can extract a large part of the heat energy in the flue gases and then releases it to the incoming combustion air.

 

Many processes produce soiled or corrosive exhaust gases which clog or attack heat exchangers.
SCHACK® Air Preheaters are highly resistant to these conditions. So if your process is not clean, then just ask us for all the options. We will even conduct a detailed analysis of the problematic materials in your flue gas flow to find the best solution for your challenge.

SCHACK® Air Preheater for Carbon Black Plants

Air Preheaters in the furnace for a carbon black process preheat combustion air for the reactors. Process gas heat is recovered and positively effects the operation cost by

 

  • Reducing fuel consumption
  • Increasing feedstock flow
  • Raising carbon black production yields
  • Minimizing quench water consumption

 

Increased air preheating temperature supports these benefits and also reduces CO2 emissions in the process.

 

 

 

Your Benefits

  • Handling of high particle loaded gases
  • Precise temperature control
  • Low tendency of fouling, leading to higher reliability
  • High flow velocity
  • Low water consumption
  • Optimized residence time
  • Optimized pressure drop
  • Quench water saving

SCHACK® Air Preheater for Sludge Incineration

Whenever we consider heat recovery for sludge incineration, the first priority is to achieve autogenous combustion.

Since these furnaces are burning a wet fuel (dewatered sludge), recuperation is usually required to preheat the combustion air.

Therefore, the most important product we supply for new furnaces is the SCHACK® Air Preheater for sludge incineration. Hot flue gas flows through the tubes and the heated medium flows over the tubes in multiple cross-counter flow passes. 

 

Your Benefits

  • High temperature air preheating reduces the consumption of combustion fuel for sludge incineration.
  • Perfect match for varying sludge feed characteristics and resulting soiled gas applications, due to the self-cleaning design.
  • Vertical tubes provide little or no area for ash to accumulate, so fouling is minimized.
  • Erosion resistance.
  • Patented tube sheet support which is tolerant to damages and minimizes leakage.
  • Long lasting design: Main and individual tubular expansion joints reducing mechanical stress.
  • Proprietary interstage bypass enables stricter control over the air preheat under varying furnace loads.

SCHACK® Air Preheater for Gasification

Air preheating is a means of increasing the conversion efficiency of the gasification process. The sensitive heat in the air causes a rise in the gasification temperature. This in turn influences the product gas composition, causing an increase in the production of combustible gases such as e.g. H2 and CO.

 

The overall efficiency of the process, which is designed on a thermal basis, can be increased when the heat required for air preheating is recovered from the gas cooling section of the plant.

 

Your Benefits:

  • Handling of high particle loaded gases
  • Precise temperature control
  • Low tendency of fouling
  • High flow velocity
  • Low water consumption
  • Optimized residence time
  • Optimized pressure drop
