Maximize Boiler Heat Recovery with Condensing Economizers

An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost. If this is a significant number to you, then you should consider adding an economizer.

Jun 08, 2018 · 6. Soot deposits The oil fired boilers are prone to soot deposits in the tube and internal boiler surface which reduces the heat transfer rate. A regular cleaning of boiler and economiser tubes must therefore be performed. Record and observe the stack temperature for indication of soot deposits.

Steam locomotive - Wikipedia

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine.These locomotives are fuelled by burning combustible material – usually coal, wood, or oil — to produce steam in a boiler.In most engines, the steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels. . Fuel and water supplies are usually

Thermal Design of Economizer for Waste Heat Recovery Boiler

Typical gas-fired heaters and boilers send 20% or more of their consumed energy out the exhaust stack. This loss can mean that for every dollar spent on fuel, the boiler system returns only 65 to 70 cents worth of useful heat after transmission losses.. If your plant operations require intensive hot water usage and your boiler load exceeds 100HP, the super efficient FLUE GAS HEAT RECLAIMER

about 20% in boiler efficiency is achieved by providing both economizer and air pre-heaters. Providing economizer alone gives only 8% efficiency increases. The Economiser enables the boiler to operate at a much higher rate of efficiency with the result of lowering the fuel usage requirements.This is due to the capture and recycling of waste heat.
