BOILER FUEL OIL ADDITIVES

​

​

Globally coal, crude oil, residual oil, gas etc., are fired as fuel in power plants. Combustion of these fossil fuels release SOx, NOx, CO2, CO, PM, Hg etc., and they need to be addressed. The residual oil has Vanadium, Sodium and Sulphur and on burning it causes corrosion in boilers, turbines and associated ancillary equipment. To combat the corrosion and to protect the environment from emissions fuel oil additives are used.

We can help the customers to manufacture/formulate a wide range of Fuel Additives used as corrosion inhibitors in residual fuels for applications in Boilers, Gas Turbines and Coal powered Boilers to improve the life of the combustion equipment and to keep the environment clean. The products proposed will be developed and manufactured using the highest quality and safety standards. It will be most economical and environmental friendly products for the customers in the Power, Oil Refinery and Marine Industries.

The fuel oil additives are applied in:

• Steam power plants • Gas turbines • Oil refining • Marine boilers

Magnesium in Fuel oil additives combats corrosion. Iron derivatives accelerates combustion. The alternate technology for improving combustion is to fire Water-in-Oil (WIO) emulsion.

Dr.Nazeer has complete range of formulations for fuel oil additives as described below:

1. Inorganic MgO or Mg(OH)2 slurries which comprise nano particles. They have large surface area, are highly reactive and consume less.
2. Our WIO technology improves combustion due to secondary atomization, reduces fouling and keeps environment clean by reducing particulates.
3. Our range of Gas turbine additives are oil soluble Organo-Metallic Magnesium and inorganic Mg(OH)2 . They inhibit Vanadic corrosion.
4. Our Organo-Metallic oxidation catalysts reduce soot up to 60% in boilers and down to 50 mg/Nm3 in turbines.

ADDITIVE REACTIONS:

Hot End Neutralization Reaction:

MgO + V2O5 → 3MgO• V2O5


V2O5 and the reactions products of Na with V formed during the combustion are low melting and highly corrosive. Magesium reacts with these corrosive products and form Magnesium Ortho Vanadate which is high melting and non-corrosive. This is soft and friable and can be removed by soot-blowers.


Cold End Neutralization Reaction:

MgO + SO3 → MgSO4
MgO + H2SO4 → MgSO4 + H2O

MgSO4 is a neutral and non-corrosive product.
