Boiler feed water is usually preheated by the waste heat extracted from the exhaust flue gas of boiler. Closed tube and shell type heat exchangers are used for feed water preheating. In the water pre - heater, flue gas is passed in the tubes (inside) and feed water on the shell side (outside). Water pre heater is generally connected with boiler feed water tank. Due to temperature difference, hot water from water pre heater goes to the feed water tank and cold water from feed tank comes to water pre - heater naturally. Thus the feed water is preheated before it is passed on to hot water boilers. It increases the fuel efficiency of the boiler. The ash content of flue gas, passing through the water pre heater is settled down at the hopper from which it is discharged through a discharge valve. Thus the water pre heater primarily reducing the air pollution level before the flue is exhausted through any pollution device like Bag filter, Cyclone separator etc. to chimney.

We provide our clients Water Pre Heaters (Heat Recovery Units) that are manufactured in compliance with industry norms. These heaters are used for reducing the fuel consumption of the steam boilers. These heat recovery units reduce the Exit Flue gas temperatore Coming out from the system Considerably in the Process enhancing the overall Performance of the system.

In case of boiler system, Water Preheater (WPH) can be provided to utilize the flue gas heat for pre-heating the boiler feed water. Consequently, there is a corresponding reduction in the fuel requirements of the boiler. For every 220 C reduction in flue gas temperature by passing through an economiser or a pre-heater, there is 1% saving of fuel in the boiler. In other words, for every 60 C rise in feed water temperature through an economiser or WPH, there is 1% saving of fuel in the boiler Salient Features of our WHR Boiler: We offer High efficiency water tube, Saturated Steam Boiler We offer you IBR grade boiler Multi pass, membrane panel design Flue gas will pass from outside Tube, Boiler suitable for Dusty gas. Water will pass from inside Tube. Modular Design. That means easy quick site work. Boiler will be located at higher elevation. NO limitations of site space. Boiler offered is with STD Min Mountings and Accessories.

Keeping with the theme of water usage and energy, this blog section is going to explore hot water pre-heaters. Now most of us are familiar with a hot water tank. Energy, commonly gas or electricity, is used to bring the water from the temperature it enters the system to a scalding temperature that we cut with cold water to bring to a temperature suitable to our needs when we use it. There are also tank-less hot water heaters that take cold water and heat it in a coil of pipe before delivering it to the end use. These have the advantage of greater energy efficiency than a hot water tank because you aren't keeping a large mass of water hot in for later use. However, in practice many people have found that tank-less hot water heaters can have a hard time keeping up with demand. The hot water pre-heater is a piece of equipment that can integrate with either of the above systems increasing their efficiency and mitigating their weaknesses. In its simplest form, a hot water pre-heater is a barrel hooked up to the hot water feed pipe before the heater proper in such a way that it holds water prior to it moving into the heater unit. You paint the barrel black and leave it out in the sun. The water in the barrel picks up heat from the sun and as a result doesn't require as much energy to heat up to its final use temperature. In practice solar pre-heaters are a little more complex, but not by much. A very simple and effective version consists of two long tanks mounted one above the other in a box with a glass top. The tanks should be black and the back of the box should be covered with a mirrored substance, like aluminum foil or a space blanket. The tanks are plumbed together so that cold water flows into the bottom of the lower tank. The top of the lower tank, on the end opposite the water input, is connected to the bottom of the top tank. The top of the top tank, on the end opposite the water input, is connected to the water heater. The pre-heater assembly should be mounted facing south with the collection glass angled for maximum sun exposure. This will generally be your latitude + 15 degrees. This is best for winter. If you want to get fancy a tilt can be added so you can compensate for the changing height of the sun in the sky over the year thus maximising the amount of solar energy the system collects. It should go without saying that the unit must have a clear exposure to the sun. As a result you may wish to angle the box off south if the direct sunlight is blocked from certain angles. Common sense and logic will dictate what should be done. In some climates units like the one described above will only be of value from mid-spring to mid-fall and if used in winter might actually cost you money by losing more heat then they gain. To deal with this it is suggested that if your area's winter temperatures routinely drop below the temperature of your input water that you install a diverter pipe so you can bypass the pre-heater in the cold months and run your water directly to the hot water heater. If you use a system like this, it is advisable to have a drain valve for the pre-heater as well as a bleeder valve at the highest point of your pre-heater's tanks to let the air out of them in the spring when you refill the pre-heater.
