Waste Heat Boilers

Product Details:

Combitherm boiler or is known among others as Combi boiler is a unique water cum smoke tube type design. It is the combination of both Water Tube Boiler and Smoke Tube Boiler where some tubes form the enclosed part of the external furnace in which water flows and rest of the tubes are placed in a shell in which flue gases flow.

Since the furnace is enclosed with the water tubes on 5 sides, it is the high-temperature zone where the radiation heat transfer takes place and the convection heat transfer takes place in a shell where water is filled in a shell and flue gases are flowing at high velocity in tubes.

Moreover, our membrane tubes design in case of Combitherm boilers/Combi Boilers is such that there are little or no losses to the environment and tubes also provide the high heat transfer area thereby increasing the radiation heat transfer.

What is Combi Boiler?

Our shell in case of combitherm (Combi Boiler) is a 2 pass design to increase the residence time and at the same time keeping the velocity optimum to achieve high convective heat transfer. Our shell and water wall tubes provide large water & steam holding capacities to give the maximum advantage.

Combitherm (Combi Boilers)Working:

• From here the water rises up in the tubes of water wall and gets thrown back to the boiler shell from the top header. As firing is done in the furnace, because of radiation the surface temperature of the water wall membrane rises and the water present in the tubes gets heated up and starts getting converted to steam.
• Now this steam, being lesser dense (creating a natural circulation of steam-water in the system), rises up to the top header and gets to the Boiler Shell. The flue gas from the furnace (1st pass), traveling in the membrane, then enters the tube of Boiler Shell. In Boiler Shell flue gasses flow in the tube.
• These Boiler Tubes are divided in 2 passes (2nd pass & 3rd Pass) where flow gas travel from both the passes and transfer heat to water through convective heat transfer. Steam coming from both the sides get collected at the top of the Boiler shell and then supplied through steam lines for the desired process application.
• 3 Pass Smoke Cum Water Tube Boiler design can burn a variety of fuels like Coal, Lignite, Rice Husk, Wood, Bagasse, Groundnut shells, and several other fuels thus providing you with lowest energy costs depending upon the fuel available in your area.
• The large furnace grate area and furnace volume in case of Combitherm Boilers provide optimum time for fuel to get burnt. On the basis of fuel firing our Combitherm boilers can be divided into 2 types: Manual firing boiler and Automatic firing boiler.
• When fuel feeding to the boiler is done manually generally in case of small capacity boilers where the amount of fuel fed to the boiler is generally less is said to be manual firing boiler and when fuel feeding is done automatically usually with the help of screw feeder, drum feeder, chain grate, pulsating grate etc. are said to be automatic firing boiler. Manual and automatic firing also depends upon the type of fuel.

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 1 year.Due to this, we provide 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.Since no fuel is fired, whatever heat we recover in the boiler is free of cost.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
• 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 (WHRB)Benefits :
• Highly Reliable in operation and robust in construction.
• Quick Payback Returns are achieved.
• One time investment with lifetime returns.
• No combustion, No emission hence Eco-friendly.
• Energy being put to use, which was getting wasted anyway.
• Waste Heat Recovery Boilers Capacity 

Product Details:

Savemax – Oil & Gas Fired Boiler are the basic 3 pass internal furnace smoke tube type design in which flue gases are inside the tubes while water is outside the tubes in the shell. The combustion of oil and gas in a furnace requires atomization of the fuel. Since the fuel entering the burner in bulk amount is either in liquid or gas form, therefore it needs to be separated in fine droplets so that every last particle of the fuel could get burnt without leaving any traces.

This process of separating the fluid particles is called atomization. Generally, atomization is done with the help of a high-pressure fan which also provides air for the combustion of fuel. Mostly burners come with the attached fan and their assembly is known as a Monobloc Burner which means fan mounted on a burner. The superior features make the boiler ideal choice in the industry Thermodyne. The 3-pass oil/gas fired boilers are most suitable for the burn fuels like heavy and light oils & gasses.

Both Oil and Natural Gas Boilers are highly efficient as the furnace temperature in case of both is around 1200 – 1300 ºC. Higher the Furnace temperature, higher will be the radiation heat transfer rate to the surrounding water. The high combustion volume, large water, and Steam holding capacity and superior design feature provide efficient operation.

Difference between Oil Fired Boiler and Gas Fired Boiler:

• Oil Fired Boilers generally require Day Oil Tank to store oil and this oil is transported to a burner through oil piping and oil pump.
• On the other hand, High-Efficiency Gas Fired Boilers are exactly same as Oil Fired Boilers in construction and the only difference is the transportation of gas to burner requires gas train which comprises of the gas regulator that regulates pressure, the gas strainer to remover dirt from gas while no such valves are required in oil fired boilers

Advantages and Benefits:

• Fully automatic and high efficiency of 88 % on NCV saves running costs to the Steam Boilers
• A large convective heating surface in the 2nd & 3rd pass tubes ensures excellent heat transfer
• Large water holding & steam holding space provides quick response to fluctuating steam demands
• Large heat transfer surface reduces the thermal stresses on the boiler surfaces
• Dry steam reduces the processing time, saved the steam & improved quality of processed goods
• Monobloc type burner – Reduce fuel consumption
• Horizontal packaged boilers– less site work & quick commissioning

Our savemax model works very smartly in a way that it saves a lot of your fuel. Both pressure and temperature gauge sense the outlet steam pressure and temperature and when it exceeds the set pressure and temperature, it automatically gives the signal to the burner which in turn reduces the fuel flow to the burner thereby reducing the operating cost.

Capacity:-

• Savemax – Oil/Gas Fired Boiler is available in capacities from 1 TPH to 10 TPH

Fuel:- 

• Liquid Fuel, heavy/light Oil, and any other Gaseous fuel, Natural Gas.
