These instant steam generateo are available from 100kg/hr to 800kg/hr capacities. Furnace oil fired systems are available from 300kg/hr capacities onward These steam generator incorporate the latest CFR technology. Here the returning gases radiate heat twice in the radiant zone with ample residence time to burn the fuel particles for complete soot-free combustion. This ensures maximum heat absorption with perfect, smokeless combustion. Filtered fuel oil pressurized by the high-pressure fuel pump passes through the fuel preheater (for heavy oil model) to the burner nozzle and develops a cone of fine oil mist. The hot swirling combustion air in the pressure jet burner mixes with fuel oil mist in an efficient air-fuel mixing device and produces a flame at super combustion efficiency giving smokeless combustion. The boiler and Accessories are mounted on common skid with attractive front instrum- -ent and control panel. The unit, pre assembled and pre-wired reduces on site erection time. The boiler can be installed close to process. The large diameter 31.8 mm OD single coil design form the rugged pressure part of the boiler. Proven and reliable components are incorporated for trouble free opera- -tion. A single switch controls the boiler operation. The burner cuts IN and OUT to meet process Heat loads and needs minimal attention during normal operation. Floor level, easy-to-reach -and read audiovisual control and instrument panel provide instant information on heat generation.. Design Benefits

We are also one of the leading firms, specialized in designing and manufacturing uni fire thermal heaters and air cooled heat exchanger, by using in-house manufactured finned tubes. Having more surface area per square feet of heat exchanger and featured with lower air resistance. These heat exchangers have leading advantage compared to other conventional & crimped type finned tube Heat Exchangers. Light in weight and the reduction in number of tubes for transfer per rate area, results in fuel saving. The combination of low friction air loses/ high air velocity and maximum heat transfer per square feet of face area also results in extremely high heating or cooling capacity of heat exchanger in a given space.
