Thermin Power is leading Waste Heat Recovery Boiler manufacturers in India, suppliers, dealers, and exporters in India. We believe in converting industrial waste into useful power thus enhancing sustainability and reducing the cost of operation by a large margin to our clients in India and the world market at large. The Waste Heat Recovery Boiler is a specifically designed heat exchanger that ingeniously recovers the enormous volume of thermal energy usually wasted in the hot, spent gases of several industrial tasks which include furnace, engines, and kilns. The WHRB uses this energy instead of letting it escape into the atmosphere and converts it into high-grade steam or hot water which is useful.
What is Waste Heat Recovery Boiler?
Waste Heat Recovery Boiler (WHRB) is a type of industrial equipment, that is used as an industrial heat exchanger, which recycles heat energy of a high-temperature fluid stream, often hot exhaust gas of industrial processes, and is then discharged to the atmosphere. This recovered heat is passed to a working fluid typically water to produce steam or hot water to be used immediately in the production processes of the plant or to produce electricity.
Hot Exhaust Intake: Hot gases of the industrial source such as furnace or engine are led immediately to the WHRB inlet and not the stack for Steam Boiler Manufacturers in India.
Heat Transfer: The working fluid is carried by a system of tubes (water-tube design or fire-tube design) onto which the hot gases pass, through which heat energy is transferred through the wall of the tubes.
Evaporation/Steam Generation: The heating of water in the tubes is sufficient to produce saturated steam in the section of the evaporator.
Cooled Gas Exit: The now cooled exhaust gases, which have now lost their beneficial heat, leave the boiler and pass to the atmosphere at a much lower temperature, and in a safe manner.
Why choose us as best waste heat recovery boiler manufacturers in India?
Customization and Engineering Capability: Select a firm that will provide custom design, which is going to be optimized to your process gas mixture, temperatures, and steam/pressure needs for Waste Heat Recovery Steam Generator.
Certifications, Quality Compliance: Confirm compliance to such critical standards as IBR (Indian Boiler Regulation) and ISO certifications that helps to prove the adherence to the strict quality and safety standards.
Established History and Track Record: Seek manufacturers with a long time history and a proven successful installation over a wide variety of industries and with difficult to work with sources of waste heat.
Fire-Tube WHRBs: The hot gases pass through tubes where they are surrounded by water; they are appropriate in lower pressure engines and engine designs that are compact, small plants.
Water-Tube WHRBs: The water is inside tubes, and is encircled by hot gases; more efficient and utilized in high pressure and high capacity applications.
By Application/Type
Heat Recovery Steam Generators (HRSGs): These are employed in conjunction with gas turbines/engines, to produce and generate high pressure steam (combine cycle plants).
Cement Plant WHRBs (PH/AQC): These are cement kiln-specific, and they retrieve heat of exits of preheater and air quenching coolers.
WHRBs Steel: Recovery of heat in furnaces (EAF, BF) and sintering machines.
Chemical/Petrochemical WHRBs: Recovery of reformers, reactors, crackers and incinerators.
Gas Engine/Turbine WHRBs: Use the heat that is emitted by industrial engines.
By Feature/Function
Composite WHRBs: Deal with heat sources.
Hybrid WHRBs: Use waste heat recovery with auxiliary fuel firing to have a constant output for Waste Heat Recovery Boiler dealers in India.
Technical Specifications of Waste Heat Recovery Boiler
We've added below a specialized table of Waste Heat Recovery Boiler in India that provides further technical specification information.
Advanced Specification
Description
Typical Metrics/Values
Engineering Significance
Pinch Point Temperature ΔTpinch
The smallest temperature difference between the hot waste gas and the saturated steam temperature in the boiler.
10∘C to 20∘C or 18∘F to 36∘F
Efficiency: Directly impacts the size and cost of the heat transfer surface. A lower pinch point requires a larger, more expensive boiler but maximizes heat recovery.
Approach Temperature ΔT approach
The temperature difference between the steam leaving the evaporator and the water entering the evaporator.
5∘C to 10∘C
Circulation: Affects the natural circulation rate in drum-type boilers; a lower approach point can lead to water wall stagnation.
Acid Dew Point TADP
The temperature at which corrosive acidic compounds like sulfuric acid, H2SO4 in the flue gas begin to condense.
Varies widely, e.g., 120∘C to 150∘C
Corrosion: The outlet gas temperature must be maintained above the TADP to prevent rapid corrosion of the boiler stack and backend sections.
Design Code Compliance
The specific engineering and safety standard the boiler construction must adhere to.
IBR (Indian Boiler Regulations), ASME (American Society of Mechanical Engineers), PED (Pressure Equipment Directive).
Safety and Legality: Mandates material selection, welding standards, and stress calculations for all pressure parts.
Steam Purity
The maximum allowable concentration of total dissolved solids (TDS) and silica in the generated steam.
TDS<1 ppm, Silica<0.02 ppm for high-pressure turbines.
Reliability: Critical for preventing fouling and stress corrosion cracking in downstream equipment, especially gas turbines.
Soot Blowing System
The method, medium, and frequency of cleaning required to remove particulate build up on heat transfer surfaces.
Type: Acoustic Horns, Retractable Soot Blowers, or Rake Blowers. Medium: High-pressure Steam or Compressed Air.
Performance Maintenance: Essential in dusty applications (Cement, Steel) to prevent efficiency loss and high-pressure drop.
Noise Level / dB(A)
The maximum noise produced by the WHRB system at a specified distance.
dB(A) at 1 meter or site boundary limit.
Environmental/Permitting: Critical for installation in densely populated or restricted areas.
Benefits of choosing us as Waste Heat Recovery Boiler suppliers in India.
We as Waste Heat Recovery Boiler suppliers in India, we provided different benefits which are given below.
Serious Savings in Fuel: Companies will be able to reduce their costs of operation and their energy expenditure by a large margin since they will be able to use free waste heat in place of fuel to produce steam.
Increased Total Energy Efficiency: Waste Heat Recovery Boiler exporters in India increases the total thermal efficiency of the plant by using the energy, which had been wasted before, maximizing the output of the original fuel input.
Reduced Carbon Release and Environmental Effect: Reusing the heat already stored in the environment will mean that more fuel does not need to be burned and this will directly reduce the emissions of greenhouse gases and other pollutants.
Short Payback period (Return on Investment): The massive fuel savings usually enable the WHRB investment to know payback within a short period of time, usually a few years of constant use for Waste Heat Recovery Boiler manufacturers in India.
Less Thermal Pollution: This technology cools down the hot exhaust gasses that enter the environment which reduces heat contamination and favors a cleaner atmosphere.
Applications of Waste Heat Recovery Boiler
We serve as Waste Heat Recovery Boiler dealers in India; it is applicable in different sites which are given below.
