This is a unique designmembrane water wall type boilercombining the advantages ofwater tube & smoke tube designs. The radiation zone of the furnace is covered on three sides by water tubes forming the first pass and the conventional smoke tube shell has tubes lined up forming the second and third pass of flue gases. Thus the water wall furnace recovers the radiation heat of the furnace and the smoke tube shell provides large water & steam holding capacities to give maximum advantage.

This 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 availability in your area.

• Flexibility of fuels with choice of agrowaste fuels
• Combines the advantage of water tube and smoke tube designs
• High thermal efficiency and low operating costs
• Dependable quality of components like valves, pumps, safeties & instruments
• Can be converted to liquid / gaseous fuels as well
• Heat recovery unitmay be offered for increased efficiency
• Easy access for cleaning and inspection

Water Cum Smoke Tube Membrane Type Boileris available in capacities from1 TPH to 15 TPH.

Agrowasteis amultiple solid fuel firing boiler in shell & tube design.The external refractory lined furnace (in customers scope) can burn variety of solid fuels like rice husk, bagasse, coal, wood, groundnut shells, saw-dust etc. thereby giving flexibility and ease of operation. The system operates on balanced draft and the flue gases from the furnace travel through the smoke tubes in theshell & tube type boiler, thereby producing steam at low cost.

Aheat recovery unitin the form of an Air or Water pre-heater may be provided to enhance the efficiency of the systems by recovering waste heat from flue gases going out of the boiler.

• Low initial investment
• Easy cleaning of flue surfaces
• Can burn low-grade agro-waste fuels
• Large convective heating surface in the tubes ensures excellent heat transfer
• Large water holding and steam holding space gives quick response to fluctuating steam demands.
• Dry steam reduces the processing time, saves steam and improves quality of processed

Agrowaste Fired External Furnace Boileris available in capacities from 1 TPH to 4 TPH.

This differs in principle from any other method of heating water or producing steam as the water within the shell is used as an electrical resistance through which the current is passed. This causes a rise in the temperature of the water.

Theseelectrical steam boilersare manufactured as a packaged unit mounted an a chassis, installation comprises the fitting of the steam pipe, cold feed, blow down, drain, safety valve, air vent pipe and the connection of the electrical supply.

The current source consists of specially designed electrodes in the form of scrolls in order to maximize the electrodes area. Automatic controls forhigh steam pressureand high & low water level inside the boiler shell are provided through a fully pre-wired control panel thereby making the operation highly user-friendly and easy.

• Compact size
• Safe, easy-to-use heat source - no on-site products of combustion.
• Easy and quick to install, they require only water connection and electrical hook-up.
• Steam available at the flip of a switch.
• Designed as per IBR 1950, duly approved from the IBR inspectorate.

Electrode Type Electrical steam Boileris available in steam capacities from 50 Kg/hr to 1320 Kg/hr

These arefully water tube design boilers for high pressure steamrequirements. Water circulation through the boiler may be either natural circulation due to density difference or by forced circulation.

• The heat of combustion is utilized more efficiently by the use of small diameter tubes in large numbers.
• To avoid large resistance to the flow of water, Powertherm boilers have a parallel set of arrangement of tubes
• The boiler components can be arranged horizontally, giving greater accessibility and operational convenience.
• All the parts are uniformly heated; therefore the danger of overheating is reduced. Also thermal stress problem is avoided.
• The tendency of scale formation is eliminated due to the high velocity of water through the boiler tubes.Can be converted to liquid / gaseous fuels as well

This, high pressure boileris available in capacities from 10 TPH to 25 TPH.

This is theconventional forced-circulation type water tube coil type boilerincorporating the unique principle of combustion known as Reverse Flow. This increases the combustion efficiency and allows a high rate of heat release. It can be offered in both IBR and Non-IBR designs.

Construction

The boiler comprises of a jacketed MS shell housing a helical coil. The combustion air is forced through the jacketed shell by means of a centrifugal blower thereby getting pre-heated. The flame travels downwards inside the coil and the flue gases reverse upwards thereby giving two passes in the radiant zone ensuring complete combustion and higher heat flux. The third pass of the flue gases is in the convective zone between the coil and the inner shell. Flue gases then travel to the Economiser forming the fourth pass.

Advantages

• Fully Automatic unit
• Unique four pass design
• High efficiency and low running cost
• Minimum site-work, low installation costs
• Instant steaming within 5 minutes of cold start
• Built-in economiser increases the operating efficiency
• Fail-safe design and dependable operating instruments

Capacity Range

Water Tube Coil Type Boileris available in capacities from 100 Kg/hr to 1200 Kg/hr

Fuel is money. The more fuel we burn in a boiler, the more money is spent. Hence even a few per cent saving in fuel bills amounts to huge savings annually. Due to this, we provide novel products like Waste heat recovery boilers. 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.

These 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.

The amount of steam generated or of heat transferred is controlled by the quantity of heat available in the flue gases. These 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 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 very handsome pay-back of investments.

These are offered in tailor-made capacities as per requirements.
