Carbon Black By Thermal Systems (Hyderabad) Pvt Ltd.

we are the largest manufacturer and supplier of carbon black in Medak, Telangana, India.
Due to low amount of CO, the heating value of the Offgas is low compared to conventional fuels like Oil and Gas. This results in low adiabatic combustion temperatures (1,300C) whereas those of Oil and Gas are high (2,000 C). The low calorific value gas needs a longer time to burn and produces an unstable flame. This shows obviously that the conventional methods used for Oil / Gas Combustion systems with membrane wall Boiler cannot be applied to Offgas. During the combustion of Offgas in direct-fired conventional membrane wall boiler, the combustion temperature is further reduced by the flame radiation (transfer of heat) to the Boiler Wall. Due to this reason, a complete combustion is not possible. Our solution to this problem is Convection Boiler with external, refractory-lined Reaction Furnace, which avoids any flame or fuel gas radiation (heat transfer) to the Boiler surfaces before fully oxidizing / combustion is completed. Due to low amount of CO, the heating value of the Offgas is low resulting in low adiabatic combustion temperatures. The low calorific value gas needs a longer time to burn.
