Waste Heat Recovery Boiler

Top Waste Heat Recovery Boiler Manufacturers in India – Shiraz Group

Shiraz Group, leading waste heat recovery boiler manufacturers in India, supplier and exporters in India, is providing the best and new technological waste heat recovery boiler that is used for recovering the heat.

This technology captures and reuses the thermal energy from the industrial process or combustion systems and helps maintain environmental sustainability. It reduces the new energy combustion and helps with cost savings. Let’s check out its multiple types, benefits and applications.

Types of our Waste heat recovery boilers (WHRB):

Being the best waste heat recovery boiler manufacturers and suppliers in India, we are offering multiple types, such as:


  • Heat Recovery Steam Generators (HRGS): These are used in the power generation industries due to their mechanisms and they capture heat from turbines, engines and industrial processes for generating steam that can be used for power generation. The new and high-temperature materials have been used, such as stainless steel and cast iron, for better efficiency.
  • Regenerative Heat Exchangers: These waste heat recovery boilers are mainly used in cement and steel production industries for transferring the heat from hot exhaust gases to cooler incoming air or fluids. The new designs and compact structure increase the versatility of the heat exchangers and allow us to use them in small-scale applications.
  • Thermoelectric Generators (TEG): Our thermoelectric generators are able to transfer or convert temperature differences directly into electrical energy using thermoelectric materials. The nanomaterials in these generators help for easy fitting even in small spaces and improve performance.
  • Vapor Compression Systems: These waste heat recovery boilers are used to recover waste heat for cooling applications by using a compressor and refrigerant cycle. We have used new technology in these systems, such as eco-friendly refrigerators for using natural refrigerators that can lower the global warming potential.

Some unique features and benefits of our waste heat recovery boiler:

As one of the former waste heat recovery boiler suppliers and exporters in India, we have added multiple types of features in our boilers, such as:

  • Improved Thermal Conductivity: This is the special capability of our WHRS that can save up to 90% and reduce any thermal loss. The new features, such as Heat Recovery Steam Generators (HRSG), help with the efficient transferring of heat and are useful in industrial sectors.
  • Smart Monitoring and Control: Our all WHRS are installed with new technological sensors that are beneficial for getting real-time data in an accurate format. This increases flexibility and allows for rapid work. The new and modern systems, such as organic Rankine cycles (ORC) and thermoelectric generators (TEG), are suitable for remote controlling.
  • High-Efficiency Heat Pipes with Nanofluids: For increasing the thermal conductivity, we have used new technology such as nanofluids that can increase the conductivity up to 10-30% overall in traditional pipes. These are used in electronics cooling, industrial applications and power plants.
  • Higher Compatibility over Renewable Energy Systems: Our all-type WHRS has the capability to connect with all types of renewable energy plants, such as biomass, solar thermal and geothermal systems. It can reduce emissions and increase sustainability by contributing to a greener environment.

Applications of our waste heat recovery boiler:

Being the best waste heat recovery boiler manufacturers and suppliers in India, all our boilers or systems are made with strong quality materials and used in certain applications, such as:

  • Industrial Furnaces: Our waste heat recovery boilers are able to recover heat from high-temperature exhaust gases to improve energy efficiency in steel and glass production.
  • Automotive Exhaust Systems: It can convert vehicle exhaust heat into electrical power, reducing fuel consumption in cars and trucks.
  • Gas Turbine Power Plants: This can easily utilize exhaust heat to produce additional steam for electricity generation, enhancing overall power output.
  • Combined Heat and Power (CHP) Plants: This can capture waste heat from power generation to provide heating or cooling for nearby facilities.
  • Cement Kilns: Our waste heat recovery boiler recycles waste heat from kiln gases to preheat raw materials, cutting fuel costs and reducing emissions.
  • Petrochemical: refineries harness residual heat from chemical processes for steam generation or electricity, optimizing energy use.
  • Data Centers: This can reuse waste heat from servers to heat nearby buildings or drive absorption chillers for cooling.
  • Food Processing: It recovers heat from cooking, drying, or pasteurization to reduce energy demand and operational costs.

As one of the best waste heat recovery boiler manufacturers, suppliers and exporters in India, we as Shiraz Group are offering our new technological waste heat recovery systems, which are highly demanding due to their cost-saving working mechanisms. It also promotes environmental sustainability and helps reduce carbon footprints, and new technological updates can increase the smoother workflow. Contact us today for information!
