Most of the boilers are fitted with accessories. They either increase the efficiency of the boiler plants or help in their working. The following accessories are attached to a modern boiler: Boiler Accessory # 1. Economizers: The greatest item of heat loss in a boiler plant is the heat carried away in the flue gases up the chimney or stack. [...]
The following article will guide you about how to calculate boiler efficiency by indirect method. Definition of Boiler Efficiency: The boiler efficiency is defined as the ratio of heat actually used for producing steam in a certain period to the heat supplied in the furnace during the same period. Both quantities being measured in the same units. The boiler efficiency [...]
In this article we will discuss about the performance test and efficiency calculation of boiler. Feed Water: The measurement of flow rate of feed water can be done by different methods. One of the best methods, if it can be arranged, is for the volume of feed water to be measured by means of two vented calibrated tanks of relatively [...]
Classification of Boiler Draught: Natural, Artificial, Steam Jet and Mechanical. Draught may be defined as the small pressure difference which causes a flow of gas to take place. In case of a boiler the function of the draught is to force air to the fire and through a boiler furnace and flue, and to discharge the products of combustion to [...]
