The most accepted method of measuring boiler efficiency is the "heat loss" method. Most Eastern Bituminous coal fired utility boilers are capable of around efficiency. It should be pointed out that 90% boiler efficiency can be maintained — yet unit heat rate penalties experienced at that given time may represent more than — or about 200 BTU
1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.
In other words, if a boiler firing Central Appalachian coal with a 12,000 Btu/pound HHV and 10% ash has a 15% flyash LOI, the losses due to LOI when calculated by the ASME code will come out real close to 1.5 % in efficiency loss of the boiler for the heat loss component attributed to carbon in ash. If the steam plant is operating at a heat

The Losses method is used to calculate boiler efficiency. Each of the different Losses is calculated to determine the efficiency. Data Required. For a coal fired boiler to calculate these losses we require the following data. Higher Heating Value of coal on as Fired Basis HHV- kJ / kg. Proximate Analysis of Coal on as Fired basis which include
Aug 29, 2017 · As an illustration, the optimum value of air excess to the combustion of natural gas is 5 to 10%, liquid fuel at the rate of 5 to 20%, and 15 to 60% for coal combustion. Boiler Thermal Efficiency. Boiler thermal efficiency shows how the performance in terms of its function as a heat exchanger.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also
Shifting to real time efficiency monitoring can improve the boiler efficiency significantly depending upon the boiler type and actual conditions at site. In nutshell, monitoring and maintaining the boiler efficiency for the overall operational life of the boiler is a must to cut fuel bills and reduce carbon footprint.
2. Boilers Bureau of Energy Efficiency 31 The coal-feed hopper runs along the entire coal-feed end of the furnace. Acoal grate is used to control the rate at which coal is fed into the furnace, and to control the thickness of the coal bed and speed of the grate. Coal must be uniform in size, as large lumps will not burn out com-
