What is the use of a damper in a boiler? - Quora

Simply saying, Damper is a device which allows you control the flow of gases through it. In Boilers, it may be used to maintain furnace pressure by controlling flow of flue gases, or in the bypass flue gas line to maintain right steam temperatures according to design, or in Draft fan blowers (ID or FD)

Boiler Economizer Types And Efficiency Calculation--

Condensing economizers. Condensing economizers are designed to accommodate the corrosive fluids generated when condensing the moisture out of the flue gas. There are 2 types of condensing economizers: heat exchanger and direct contact (spray). They capture much more heat and therefore can raise the overall boiler efficiency by 10% to 15%.

What is an Economizer? How an Economizer Works

Dampers control the air introduced, recirculated or exhausted from a space. Logic controllers and outside temperature sensors determine if the conditions are right for the economizer to function. The actuators open and close the dampers based on the commands from the logic controllers.

Exhaust Gas Boilers And Economisers working procedure

Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.

What is the function of economizer in steam power plant

A common application of economizers in steam power plant is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
