Description of oil fired steam boiler

ASCENT’s Steam Boiler is a versatile, Fuel efficient, Oil Fired three pass multi-tube boiler with wet back design, which guarantees high thermal efficiency. Oil fired Steam boilers up to three tons/hr is Reverse Flue Design and all other models are conventional three pass wet back design.

Our Oil fired boilers are fabricated according to the latest IBR act. Large Furnaces ensure complete combustion of Fuel with small NOX emissions with high radiant heat transfer. Big Smoke tubes with Gas Spirals ensure a high rate of convective heat transfer. All welds are subjected to shear rather than tension. Impeccable internal water circulation system ensures even thermal expansion. Extremely strict quality control throughout different stages of manufacturing, Hydraulic tests, Individual assembly tests and complete inspection of boilers on completion provides trouble free operation and Longer life.

Oil Fired Boiler Working Principle

Operation & maintenance: – Front and back doors can be completely removed for cleaning and maintenance. Detachable gas spirals with smoke tubes makes cleaning easy as most of the dust deposit comes along with the spirals.

Firing Equipment: – Rugged Forced draft, Fuel efficient pressure jet burner delivers comprehensive combustion with 1:3 turndown Ratio. Fuel pumping and heating unit, combustion blower and control panel is reserved at operating level for stress-free operation and maintenance.

Dry Steam: – The huge steam volume with high disengaging surface & in-built steam separator guarantees steady, dry steam with 0.98 dryness fraction.

Safe Functioning: – Oil fired steam boiler is equipped with IBR boiler fittings, low level trip, auto level controller, steam safety valve, high pressure trip, level indicators, auto/manual control and essential electrical switchgear and controls for safe operation. Fail safe trips offer maximum protection to steam boilers.

Advantages of Oil Fired Steam Boiler

INSTANT STEAM: – Water tube design with low thermal stored energy organized in a cross flow pattern generates steam at full working pressure within five minutes from cold start.
SUPER EFFICIENCY: – The 4-pass Firetech Insta Vapor Instant Steam Generator with central air heater and in-built economizer attains a super efficiency of 90 %.
BOILER REGULATION: – Insta Vapor Steam Generator is sanctioned under Small Indian Boiler regulations and therefore eliminates the need for IBR operator.
NO EXPLOSION RISKS: – Insta Vapor Steam Generator delivers low thermal inertia system and with completely automatic safety trips ensures totally safe operation.
TROUBLE FREE OPERATION: – The huge diameter single coil design forms the rugged pressure part of the boiler. Proven and consistent components are integrated for trouble free operation.
COMPLETE COMBUSTION: – These industrial steam boilers integrate the modern CFR technology. Here the returning gases discharge heat twice in the radiant zone with sufficient residence time to burn the fuel particles for complete soot-free combustion. This ensures maximum heat absorption with impeccable, smokeless combustion.
