The steam-actuated plug is installed on the end of a pipe outside the drum. The other end of the pipe, which is open, is at the lowest permissible water level in the steam drum. A valve is usually installed between the plug and the drum. The metal in the plug melts at a temperature below that of the steam in the boiler.
To prevent boiler tube chocking and overheating of the boiler tubes the blow down is necessary. The blow down is the water removed from boiler to maintain the solids level in the boiler drum. This can be calculated as follows: E = Evaporation or steam generation rate.
often referred to as oil-fired, gas-fired, coal-fired, or solid fuel –fired boilers. The boilers can be classified according to the following criteria. According to flow of water and hot gases. 2.2.1. Water tube. 2.2.2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes.
The heart of an industrial boiler system is a hot water or steam boiler operated with a certain kind of fuel. The boiler heats up or evaporates the water inside it, which is then transported to the consumers via pipe systems. In case of hot water the transport energy is generated by pumps, in case of steam the transport is based on inherent

system is the method used to optimise the coal combustion in the boiler. This is affected by coal quality, boiler cleanliness and equipment deterioration as well as by the even distribution of the pulverised fuel to the burners. Expert systems for assessing coal quality and its implications for power generation have been and continue to be developed.
Chemical Energy to Heat Energy: Chemical energy is stored in coal is converted into heat by the process known as combustion. The carbon and other combustible elements in coal are made to unite with Oxygen of air in furnaces. This process converts chemical energy into heat energy.
2.3.1 Essentials of Steam Power Plant Equipment Steam Power Plant. A steam power plant must have following equipment : (a) A furnace to burn the fuel. (b) Steam generator or boiler containing water. Heat generated in the furnace is utilized to convert water into steam.
circulating fluidized-bed boilers involves a two-stage combustion process: the reducing combustion at the fluidized-bed section, and the oxidizing combustion at the freeboard section. Next, the unburned carbon is collected by a high-temperature cyclone located at the boiler exit to recycle to the boiler, thus increasing the denitration efficiency.
When evaluating the prospect of converting a coal-fired boiler to natural gas, there are a number of factors that need to be independently evaluated. The combustion system modifications and boiler performance impacts are several important aspects to be considered. The combustion system
