2003-10-30 · Once through boilers: in once-through boilers the pressure loss of the evaporator is between 5 and 30 %. Forced and natural circulation boilers: the pressure drop in the evaporator part of drum-based boilers does not affect the pressure loss of the main steam/water flow through the boiler.

Flue-gas stack - Wikipedia

2019-5-12 · A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

type of heat loss in boiler and their prevention


2019-5-5 · in this article we discussed about the (type of heat loss in boiler and their prevention) .Types of heat loss in boilers in power plant: 1. Loss due to dry flue gas 2. Loss due to hydrogen in fuel 3. Loss due to moisture in fuel 4. Loss due to moisture in air 5. Loss due to carbon monoxide

Flue gas - Wikipedia


2019-5-19 · Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of

Understanding Boiler Stack Losses - Forbes Marshall

A common trend observed is, as boiler is operated continuously, the measured outlet temperature of flue gases increases. After operation for a few months, significant rise in flue gas temperature and hence stack losses is observed. The reason behind this is, as a boiler is operated, scales are formed on the boiler …
