Basics of boilers and boiler processes Definition In a traditional context, a boiler is an enclosed container that provides a means for heat from combustion to be transferred into the working media (usually water) until it becomes heated or a gas (steam). One could simply say that a boiler is as a heat exchanger between fire and water. The

A convection superheater is located in the convective zone of the furnace usually ahead of economizer ( in the path of the hot flue gases). These are also called primary superheaters. A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system.

In thu early 1900's, the chemical recovery function was achieved in smelters or roasters wherein black liquor was burnt to recover inorganic chemicals and the heat energy was either wasted or partially recovered. The 1930's to 1950's saw the introduction of tangent tube water wall bi-drum boilers which put the emphasis on chemical recovery and also on heat recovery to produce steam for ...

The purpose of this Recommended Good Practice is to provide guidelines for the design, installation, and operation of Recovery Boiler Basic Process Control Systems (RBBPCS) and Recovery Boiler Safety Systems (RBSS) to contribute to operating safely. No recommendations can be promulgated which will guarantee the elimination of furnace explosions.
'Boiler feed water pump' pumps the water at high pressure into the boiler from the 'feed water tank'. The pump is akin to the heart in the human body. Pre-Heating 'Feed water heaters', using extracted steam from the turbine, adds a part of the sensible heat even before the water enters the boiler. Economiser.

Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler. Key Components of Boilers are:-Burner – The burner is the component of boiler that provides the heat that heats the water of system. The fuels used can be natural gas or oil.
The kraft recovery boiler is made up of two main sections, the fireside, or furnace, where the black liquor is burned and the heat transfer section where steam is created. This module describes the purpose and operation of a kraft recovery boiler in the kraft pulping process.
Recovery boiler is the part of Kraft process of pulping where chemicals for white liquor are recovered and reformed from black liquor, which contains lignin from previously processed wood. The black liquor is burned, generating heat, which is usually used in the process or in making electricity, ...
