A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Calorific Value. The calorific value of coal is measured for almost all coal samples. It is a measure of the heating ability of a coal and is needed to estimate the amount of coal needed to produce a desired amount of heat. Calorific values are also used to define coal rank in low and mediumrank coals below the rank of mediumvolatile ...
The calorific value of coal is the heat liberated by its complete combustion with oxygen. Most applications which burn fuel produce water vapor which is not used, and thus wasting its heat...
The coal samples were sent to the analysis lab to make quantitative evaluation of the coal calorific value, and the reported data of each sample was taken as the averaged value during the corresponding time of coal powder sampling.
The effect of the coal calorific value variation on the steam temperature characteristics is revealed. • The effect of calorific value variation on the boiler efficiency is revealed. • This study provides guidance on the doublereheat ultrasupercritical boiler operation under coal variation. Abstract Keywords Doublereheat ultrasupercritical unit
A 65000kW thermal power station uses coal of calorific value 15000 kcal per kg. if the coal consumption per kWh is kg and the load factor of the station is 40%, calculate (i) the overall efficiency (ii) coal consumption per day. A diesel engine power plant has one 600 kW and two 250 kW generating units.
The calorific value of 5000 kcal/kg and its price is (4700) IDQ per ton. The thermal efficiency of the station is 35% while electrical efficiency is 85%. A 75 MW thermal power station uses coal of calorific value of 6400kcal/kg. Thermal efficiency of the station is 30% while electrical efficiency is 80%. Calculate the coal consumption per hour ...
This paper presents the thermal and economic performance of a 210 MWe coalfired power plant situated in North India. Analysis is used to predict coal consumption rate, overall thermal efficiency, mass flow rate of steam through boiler, and Net present value (NPV) of plant for given load. Thermodynamic analysis was carried out using mass and energy equations followed by empirical ...

The calorific value of coal has a linear dependence on the ash content in coal. Results of determination of the calorific value by the correlation method fitted well at the medium moisture samples ...
India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Several methods are available to predict GCV using either moisture content and ...
1. Introduction. Today, the lignite is one of the cheapest energy sources [1, 2].The lignite reserves constitute about 45% of the total coal reserves and are distributed throughout the world [].The lowrank coals (LRCs) including the brown and the subbituminous coals, which are known to contain high moisture content (up to 65%, wet basis), are very important for the LRCfired power plants, the ...

The procedures for the insitu measurement of the GCV of coal in a power plant are illustrated in Fig. 1. First, the coal sample is collected into a metal crucible from a coal piping by a sampling gun. Secondly, the coal sample is weighed and the weight is recorded using an analytical balance with a precision of mg.
Results from proximate analysis expose the gross composition of coal. The air dried results indicate that, the moisture content varies from to %, ash content ranges from to % ...
In this table, calorific values for different types of coal and coal products are shown on a country by country basis. The aggregates for hard coal and brown coal are included for years prior to 1978 only. This table provides the calorific values used to convert raw tonnes of coal and coal products into energy for the OECD Coal Balance data.
