Waste Heat Recovery Boiler [WHRB] : Wastetherm 
The Waste Heat Recovery Boiler, also known as WHRB or Wastetherm, is a boiler that uses waste heat from industrial processes to generate steam or hot water. It is commonly used in industries such as thermal power plants, cement plants, steel mills, and chemical plants, where a significant amount of heat is released as waste.
The WHRB utilizes this waste heat to produce steam, which can be used for various purposes such as power generation, heating, or process requirements. By recovering and reusing the waste heat, the WHRB helps to improve energy efficiency and reduce fuel consumption, thereby reducing greenhouse gas emissions and operating costs.
The WHRB typically consists of heat exchangers, a boilers drum, steam drum, and various control systems. The waste heat is transferred from the flue gases or exhaust gases of the industrial process to the water or steam in the heat exchangers. The recovered heat is then used to generate steam, which can be sent to a steam turbine for power generation or used directly for heating or other purposes.
WHRB offers a sustainable solution for utilizing waste heat, reducing energy consumption, and minimizing environmental impact in industries.
What is waste heat recovery Boiler
Waste heat recovery boiler is a device that uses the heat from waste gases to generate steam or hot water. This heat can then be used for a variety of purposes, such as heating buildings, generating electricity, or driving industrial processes.
Waste heat boilers work by passing the waste gases from a combustion process through a series of tubes filled with water or steam. The heat from the gases is transferred to the water or steam, which is then used to generate steam or hot water.
Waste heat recovery boiler operational working
Though in this case, you are not using extra fuel in your equipment still there are a huge amount of flue gas losses.
Waste Heat Recovery Boiler
This heat can be utilized somewhere in a process where you are currently using fuel to generate heat either to produce steam or even for local heating of water or air or any other fluids.
Remember energy is precious, even small saving in energy cost will save you a lot of money which can usually be seen over a period of years.
Due to this, Thermodyne provides novel products like Wastetherm, the Waste Heat Recovery Boilers (WHRB). As the name suggests, the heat going waste from the process like flue gases of Diesel Generator sets is utilized in these boilers to generate hot water or steam.
Waste heat recovery boiler design
Waste Heat Recovery boilers are designed to recover heat from waste flue gases from DG exhaust, Furnace exhaust, Kiln exhaust, incinerator exhaust etc. to produce steam or hot water based on the application requirements of the plant.
There are 4 basic requirements or inputs for calculating your waste heat from the source. These are:-
- Type of fuel and its composition
- Amount of flue gases leaving the exhaust per hour in Kg/hr or Nm3/hr
- The temperature of flue gases at the exhaust in ℃
- The process where you want to utilize this waste heat.
The amount of steam generators or Steam Boilers of heat transfer is controlled by the quantity of heat available in the flue gases. Wastetherm can be fire tube or water tube type as per the design requirements.
Tailor-made solutions are offered based on specific requirements of customers and the Wastetherm boiler (waste heat recovery boiler) design is integrated into the system requirements. Since these boilers operate on waste heat, there are no fuel bills to operate these and hence they offer the very handsome payback of investments.
Wastetherm can be either a smoke tube design or water tube design. Depending upon the amount of waste heat available and the process where you want to utilize this waste heat say for an instance for producing steam, the required capacity and pressure of steam will help to determine the design of a waste heat boiler.

Waste Heat Recovery Boilers FAQs
What is WHRB boiler full form?
WHRB — Waste Heat Recovery Boiler
What are waste heat boilers?
Waste heat recovery boilers are designed to reduce heat energy wastage. WHR Boilers utilise waste heat or hot waste air flows from process for heating water. In simple words WHR Boilers are energy recovery heat exchangers.
What are the direct and indirect benefits of waste heat recovery?
Waste heat recovery has direct effect on the efficiency of the whole process and system. Recovery of waste heat can result in low process cost, reduction in utilities consumption. There are several other indirect benefits of waste heat recovery such as reduction in fuel consumption etc.
Which boilers has the highest heat transfer capacity?
Supercritical boilers
A waste heat boiler is a device that uses the heat from waste gases to generate steam or hot water. This heat can then be used for a variety of purposes, such as heating buildings, generating electricity, or driving industrial processes.
Waste heat boilers work by passing the waste gases from a combustion process through a series of tubes filled with water or steam. The heat from the gases is transferred to the water or steam, which is then used to generate steam or hot water.
There are many benefits to using a waste heat recovery boiler, including:
Reduced energy consumption: Waste heat recovery boilers can help to reduce energy consumption by capturing and using the heat that would otherwise be wasted.
Reduced emissions: Waste heat boilers can help to reduce emissions by using the heat from waste gases to generate steam or hot water, instead of burning additional fuel.
Increased efficiency: Waste heat boilers can help to increase the efficiency of a facility by capturing and using the heat that would otherwise be wasted.
There are two main types of waste heat recovery boilers:
Recuperative boilers: Recuperative boilers use a heat exchanger to transfer heat from the waste gases to the water or steam.
Regenerative boilers: Regenerative boilers use a series of rotating disks to transfer heat from the waste gases to the water or steam.
The factors to consider when choosing a waste heat recovery boilers include:
The type of waste gas that will be used
The temperature and pressure of the waste gas
The amount of heat that needs to be recovered
The cost of the boiler
The cost of a waste heat recovery boiler varies depending on the type of boiler, the size of the boiler, and the manufacturer. In general, waste heat boilers cost between RS 10,000 and Rs 800,000.
Waste heat recovery boilers can last for many years with proper maintenance. In general, waste heat boilers can last for 20 to 30 years.
Waste heat recovery boilers should be inspected and maintained on a regular basis to ensure that they are operating properly. The frequency of maintenance will vary depending on the type of boiler and the environment in which it is operating.
Waste heat recovery boilers can be purchased from a variety of manufacturers and distributors. A good place to start your search is online.
Once you have chosen a waste heat recovery boiler, you will need to find a qualified installer. A good place to start your search is with the manufacturer of the boiler.
