SOLID FUEL BURNERS

PETCOKE

 

COAL

 

BIOMASS

The use of a particular type of solid fuel burner is intimately linked to the type of kiln on which the burner is installed. Coal as well as pet coke or biomass products are cheap fuels and widespread in many countries of the world. India is one of those. Today, coal as fuel for kilns in India is generally used badly with coarse feeding systems with large and uncontrolled size of its particles. As a result an inefficient combustion, strong atmospheric pollution, high consumption, considerable workers effort, extremely hard work, is obtained. The use of a modern solid fuel burner makes possible to check the air / fuel ratio which is near to the stoichiometric ratio, also minimum quantity required as a function of the internal temperature of the furnace, reduction and perfect control of fuel granulometry. It is logic: reducing the granulometry of coal approaches it to gas characteristics with more efficiency in the combustion.

 

 

MULTIJET SYSTEM

FOR TUNNEL KILN: it is  required a burner that can guarantee a controlled fuel / air ratio for each feed nozzle, a good size with a constant particle size of less than 1 micron of the fuel; it does not need to be manageable. it is the most sophisticated solid fuel burner in the world, The production of the coal powder according to a well determined and constant granulomentry is performed upstream of the combustion plant.  The Multijet system is the only one on the mondial panorama that can satisfy all the parameters required by an efficient combustion similar to that obtained from the gas:

  • Perfect control of a constant and very fine grain size
  • Mechanical transport of coal dust
  • Autonomy of each power supply based on the specific temperature set
  • Absolute absence of vibrations on the oven
  • Air / fuel controlled ratio on each of the injectors independent of the ratio set on the other injectors.

Combustion similar to that obtained with the use of gas as fuel. Itr can also be proposed in Hybrid form (Coal / gas or Coal / heavy oil). 

 

SELF GRINDING SYSTEM

FOR STATIC KILN: it is required a burner that can guarantee a controlled fuel/air ratio, a good size of the fuel and above all that to be easy to handle. Basically the machine has to be not too cumbersome and heavy. We suggest using burners "self grinding" type having a small mill of built-in grinding. The grain size will be good but not perfectly controllable. It depends essentially on the wear and tear of the mill hammers over time. We could supply one machine for local industrial test before purchasing.

Solid Burning equipment for following types of brick kiln:

  • FIXED CHIMNEY BULL’S TRENCH KILN (FCBTK)
  • NATURAL DRAUGHT ZIGZAG KILN (NDZK)
  • HOFFMAN KILN
