THERMIN ENERGY SYSTEM PVT. LTD.

Bhosari, Pune, Maharashtra

We provide Waste Heat Recovery Boilers ( WHRB ) / Steam Generators on Natural Gas / Bio Gas /HFO /FO/ HSD based Engines/Turbines and Waste heat coming from different processes like GLASS Furnace exhaust, Melting Furnaces Exhaust, Cement Kiln Waste Gases. The Huge Power Cost Hike and increase of power demand in Industry segment we all has to take each and every chance to trap the waste heat and generate steam possibly for Combined Power Plant or for process steam/Hot water application. The waste heat recovery project is viable only depending on the investment recovery period. WeTHERMIN ENERGY SYSTEMare very well know this fact and are designing/manufacturing/supplying the systems which gets maximum possible monitory outputs and in minimum time frame.THERMIN ENERGY SYSTEMoffers Smoke Tube and Water tube Boilers for such applications. The Systems offering are totally customized turnkey solutions.

In deaeration, dissolved gases, such as oxygen and carbon dioxide, are expelled by preheating the feed water before it enters the boiler.

All natural waters contain dissolved gases in solution. Certain gases, such as carbon dioxide and oxygen, greatly increase corrosion. When heated in boiler systems, carbon dioxide (CO2) and oxygen (O2) are released as gases and combine with water (H2O) to form carbonic acid, (H2CO3).

Removal of oxygen, carbon dioxide and other non-condensable gases from boiler feed water is vital to boiler equipment longevity as well as safety of operation. Carbonic acid corrodes metal reducing the life of equipment and piping. It also dissolves iron (Fe) which when returned to the boiler precipitates and causes scaling on the boiler and tubes. This scale not only contributes to reducing the life of the equipment but also increases the amount of energy needed to achieve heat transfer.

Air Preheaters
An air preheater (APH) is any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.

Typically, the flue gases leaving a modern 3-pass shell boiler are at temperatures of 200 to 300 C. Thus, there is a potential to recover heat from these gases. The flue gas exit temperature from a boiler is usually maintained at a minimum of 175 C, so that the sulphur oxides in the flue gas do not condense and cause corrosion in heat transfer surfaces. When a clean fuel such as natural gas, LPG or gas oil is used, the economy of heat recovery must be worked out, as the flue gas temperature may be well below 200C.

The potential for energy saving depends on the type of boiler installed and the fuel used. For a typically older model shell boiler, with a flue gas exit temperature of 260C, an economizer could be used to reduce it to 200C, increasing the feed water temperature by 15C. Increase in overall thermal efficiency would be in the order of 3%. For a modern 3-pass shell boiler firing natural gas with a flue gas exit temperature of 140C a condensing economizer would reduce the exit temperature to 65C increasing thermal efficiency by 5%.

Depending on fuel used for firing, THERMIN ENERGY provides bare tube, finned tube, gilled tube Economisers /Water Preheaters.
