IBR Steam Boiler Manufacturer in India

An IBR steam boiler is a regulated industrial steam boiler governed by the Boilers Act, 2025 (which repealed the Indian Boilers Act, 1923 and came into force on 1 May 2025) together with the applicable Indian Boiler Regulations (IBR). Under the Boilers Act, 2025, any closed pressure vessel generating steam for external use with a water capacity of 25 litres or more (measured from the feed check valve to the main steam stop valve) or a design/working pressure of 1 kg/cm² or more falls under IBR purview, requiring IBR-compliant design, material traceability, certified welding, and statutory inspection.

Under the Boilers Act, 2025 (effective 1 May 2025) and the Indian Boiler Regulations, a Non-IBR steam boiler stays below the statutory threshold—operating below 25 litres water capacity or below 1 kg/cm² design and working pressure (or meeting specific statutory coil/exemption conditions)—whereas an IBR steam boiler covers vessels of 25 litres or more at 1 kg/cm² or higher, such as 1 TPH to 10 TPH industrial units at 10.54 to 17.5 kg/cm². IBR boilers require approved design drawings, boiler-quality materials, and statutory registration/inspection. Plants needing smaller capacities can review our Non-IBR boiler buying guide or read our Boilers Act, 2025 IBR steam boiler guide.

Thermokrupp Boilers manufactures industrial IBR steam boilers across a capacity range of 1 TPH to 10 TPH (1,000 kg/hr to 10,000 kg/hr), covering standard plant capacities including 1 TPH, 2 TPH, 3 TPH, 4 TPH, 5 TPH, 6 TPH, 8 TPH, and 10 TPH. Exact capacity and boiler model availability depend on the selected boiler configuration, fuel arrangement, and project engineering design.

Our IBR steam boiler range is offered with working pressures from 10.54 kg/cm² to 17.5 kg/cm². The required working pressure for your boiler is confirmed based on your process heating temperature requirement, pressure drop across the steam distribution header, and applicable statutory design codes.

An IBR wood fired steam boiler is a solid-fuel industrial steam boiler engineered to burn wood-based biomass—such as seasoned wood logs, wood chips, or biomass briquettes where matched to the furnace design—inside an IBR-compliant pressure-part assembly. It generates continuous process steam from 1,000 to 10,000 kg/hr at working pressures between 10.54 and 17.5 kg/cm² for manufacturing plants.

An external furnace type solid fuel boiler separates the combustion zone from the main cylindrical boiler shell by housing a refractory-lined combustion chamber outside the pressure vessel. Solid fuel burns on a dedicated grate inside this external furnace, and hot flue gases travel through a refractory duct into the multi-pass boiler tubes, providing larger combustion volume, controlled flame contact, and easier ash cleaning.

Depending on the selected furnace geometry, grate design, and fuel-feeding arrangement, an IBR wood fired or external furnace solid fuel boiler can be configured for wood logs, wood chips, sawdust briquettes, agro-waste briquettes, or compatible solid fuels. Fuel sizing, moisture content, and ash behaviour must be evaluated during project engineering before confirming multi-fuel compatibility.

Industrial IBR steam boilers are widely used across food processing, textiles and dyeing, pharmaceuticals, chemical manufacturing, paper and pulp, packaging and corrugation, rubber vulcanisation, dairy and beverages, rice mills and agro-processing, and other continuous manufacturing plants requiring steady process steam at 10.54 to 17.5 kg/cm².

Selecting the right capacity from 1 TPH to 10 TPH requires calculating peak and average process steam demand (in kg/hr), accounting for steam header and condensate losses, confirming required process pressure, and reviewing future plant expansion plans. Sharing your process heat load and shift schedule with our engineering team helps prevent undersizing or inefficient part-load operation.

Working pressure is the actual operating pressure at which steam is continuously generated and supplied to your factory header—between 10.54 and 17.5 kg/cm² in this Thermokrupp range. Design pressure is a higher structural pressure value specified above the maximum working pressure for pressure-part thickness calculations, hydrostatic testing, and safety relief valve settings.

The capital cost of an IBR steam boiler depends on steam capacity (1 TPH to 10 TPH), working pressure (10.54 to 17.5 kg/cm²), boiler configuration (wood fired, external furnace solid fuel, or packaged industrial steam boiler), fuel feeding and ash handling automation, air pollution control equipment such as multi-cyclone dust collectors, heat recovery add-ons, and site commissioning scope.

Yes, Thermokrupp Boilers provides project requirement assessment, boiler selection support, installation guidance, commissioning assistance, operator orientation, spare parts supply, and annual maintenance support subject to the agreed project scope. You can review our dedicated support offerings through our boiler engineering and service desk.

Yes. While 1 TPH to 10 TPH and 10.54 to 17.5 kg/cm² represent our offered industrial range, furnace configuration, grate type, fuel handling layout, instrumentation, and flue-gas cleaning equipment can be custom-engineered around your plant space, locally available solid fuels, and steam load profile.

To prepare an accurate technical and commercial quotation, please share your required steam capacity (kg/hr or TPH), target working pressure (kg/cm²), preferred fuel type and fuel sizing, daily operating hours, feedwater conditions, and installation city or state.
