Gas Fired IBR Steam Boilers

Description of Gas Fired steam boiler

An IBR Gas Fired steam boiler is a type of industrial boiler that uses natural gas as its fuel source to generate steam. It is designed in compliance with the Indian Boiler Regulations (IBR), a set of regulations that govern the design, construction, and operation of boilers in India.

The Gas Fired steam boiler works by heating water in a closed vessel to generate steam. The natural gas is burned in the combustion chamber, producing heat that is transferred to the water. As the water heats up, it begins to boil, generating steam that is used in various industrial processes. One of the primary advantages of using natural gas as a fuel source for the steam boiler is its low environmental impact. Natural gas is a relatively clean-burning fuel, producing fewer emissions than other fossil fuels. This makes it an environmentally friendly option for industrial processes that require steam.

In conclusion, the IBR Gas Fired steam boiler is a highly efficient and reliable industrial boiler that uses natural gas as its fuel source to generate steam. Its compliance with Indian Boiler Regulations (IBR), advanced safety and control systems, and low environmental impact make it an excellent choice for businesses that require steam for their industrial processes.

Gas Fired Boiler Working

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: – Gas 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 Gas Fired Steam Boiler

1. Reliable Performance: The Supratech steam boiler is an efficient, versatile, and fuel-efficient three-pass multi-tube boiler with a wet back design, ensuring high thermal efficiency for both Oil and Gas firing options.
2. Construction: Our boilers are constructed in accordance with the latest IBR act, ensuring complete combustion of fuel with low NOX emissions, thanks to the large furnace and high radiant heat transfer. Our strict quality control procedures, including hydraulic and assembly tests, ensure a trouble-free operation and longer life.
3. Firing Systems: The rugged forced draft, fuel-efficient pressure jet burner provides complete combustion with 1:3 turndown ratio. The fuel pumping and heating unit, combustion blower, and control panel are kept at the operating level for easy operation and maintenance.
4. Steam Output & Dryness: Our boilers feature a large steam volume with a disengaging surface and built-in steam separator to ensure steady, dry steam with a 0.98 dryness fraction.
5. Longevity: Our boilers are constructed from high-quality steel plates and IBR certified tubes, ensuring a long life. The perfect internal water circulation system guarantees even expansion, further increasing the lifespan of the boiler. Our strict quality control procedures during construction, hydraulic tests, and overall inspection ensure trouble-free operation and long life.

List of Components 

1. Pressure Part Assembly: The offered gas-fired steam boiler includes one pressure part assembly, which comprises a fully fused welded shell with a wetback furnace and two sets of convection smoke tubes. The front doors of the assembly are hinged, and they are lined with ceramic or high alumina firebrat for added protection. The smoke chamber features a soot cleaning door, while the boiler shell has one manhole and two mud holes for internal inspection. Additionally, there is an access opening at the back of the IRC to inspect the furnace’s interior. The assembly also features two fusible plugs for mechanical safety in case of very low water levels.
2. LPG Fired Burner Assembly: The gas-fired steam boiler also includes one LPG fired burner assembly with an AR gear ratio for full modulation.
3. Combustion Air Fans: To create positive draught inside the boiler, the gas-fired steam boiler has one backward curved design forced draft combustion air fan with a motor.
4. Feed Water Pumps: Two highly efficient centrifugal multi-stage, vertical feed water pumps with a motor are also included in the boiler. The pump’s impellers and shaft are made of stainless steel for added durability.
5. Control Panel Box Assembly: 
   1. Panel box specification: – The control panel box assembly for the gas-fired steam boiler includes a power cum control panel, free-standing type, confirming to IP 42 with necessary starters required. The panel is made out of 14 / 16 SWG CRCA sheets and painted with polyurethane paints, synthetic enamel, or powder-coated. The power section is provided with a main incomer isolating switch, and the required switch gears for all the feeders are housed in the power section. The control panel also features one temp indicator and switch to indicate the boiler stack temp. This switch gives a high stack temp alarm, lamp indication, and burner trip interlock. Additionally, there is one sequence controller for the burner management system. 
   2. Set of instruments: – The set of instruments includes one pressure indicator to indicate steam pressure, one pressure switch/temp relay for stepless modulation, one pressure switch for burner ON/OFF control, one pressure switch to sense low combustion air pressure, and one pressure switch to sense low fuel pressure.

1. Accessories: 

1. Piping: – The gas-fired steam boiler also includes piping and a set of valves, mountings, and fittings. The piping comprises one set of feed piping to connect feed water pumps to the boiler, along with a set of valves and fittings to be fitted with the feed piping. There are two stop valves on the feed water line and two non-return valves on the same line.
2. Set of valves mountings & fittings for the boiler: – The set of valves, mountings, and fittings for the boiler includes one main steam stop valve, two spring-loaded single port safety valves, one air vent valve, one blowdown valve, one main steam pressure gauge, two plain tubular gauge glasses along with inbuilt isolation and drain valves, two float-operated magnetic water level controllers, and three isolation valves for the main steam pressure gauge, inspector pressure gauge isolation valve, and drain valve for two float-operated level controllers.
