Instant Steam Generator
CFR - TECHNOLOGY: In the Counter Flue Radiation (CFR) technology 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.
FLUE GAS ROUTING: The flue gases rise through the combustion chamber with maximum radiant heat transfer and
then descend through the third pass between the outer cylindrical tube section and the gas-tight smoke box casing.
COMBUSTION SYSTEM: Filtered fuel oil pressurized by the high-pressure fuel pump passes through the fuel
preheater (heavy oil model and model CT-30 onwards) 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.
OPTIMUM HEAT UTILIZATION: The radiation and convective helical coil absorb maximum heat from the hot flue
gases twice in radiation zone and once in convection zone in cross-flow pattern. The residual heat in flue gases
picked up by the incoming combustion air and water ensure optimum heat utilization.
COMBUSTION CHAMBER: The cylindrical combustion chamber is dimensioned and designed for optimal
combustion and generously sized as per DIN 4754.
ULTRA MODERN, SLEEK & ELEGANT DESIGN: The boiler and Accessories are mounted on common skid with
attractive front instrument and control panel. The unit, pre assembled and pre-wired reduces on site erection time.
The boiler can be installed close to process.
RELIABLE OPERATION: 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 operation.
FULLY AUTOMATIC SAFE OPERATION AND INSTANT INFORMATION: 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 audio visual control and instrument panel provide instant information
on heat generation.



                                                       Design Benefits
INSTANT STEAM: Water tube design with low thermal stored energy arranged in cross flow pattern produces steam at full working
pressure within five minutes from cold start.
SUPER EFFICIENCY: The 4-pass Instavapor Instant Steam Generator with integral air heater and built in economizer achieves a
super efficiency of 90 %
NO BOILER REGULATION: Instavapor Steam Generator is outside the purview of Indian Boiler regulations and therefore eliminates
the need for annual shutdown
NO EXPLOSION RISKS: Instavapor Steam Generator offers low thermal inertia system and with fully automatic safety trips ensures
fully safe operation.
