Industrial Boiler Heat Recovery & Energy Efficiency Heat recovery systems play an important role in improving the efficiency of an industrial steam boiler, reducing costs while decreasing CO2 emissions and lowering a plant's carbon footprint.
The use of Industrial Biomass Boilers in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and electricity with less effect on the environment than fossil fuels.This type of energy production has a limited long term effect on the environment because the carbon in biomass is part of the natural carbon cycle; while the carbon in fossil fuels is not, and permanently adds carbon to the environment when burned for fuel
Boiler Efficiency is in general indicated by either Thermal Efficiency or Fuel to Fluid Efficiency depending on the context. Combustion Efficiency – indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency – indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boilers, exclusive radiation, and convection losses

Nov 24, 2016 · Boiler Efficiency:-Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.
Unparalleled energy efficiency There are basically two standards of measuring a boiler system’s efficiency: its fuel-to-steam efficiency (how much fuel it consumes at maximum capacity) and its in-service efficiency (how a boiler system responds in everyday use). The LX Series Industrial Boilers exceed expectations in both categories.
The principal objective of the Efficient Industrial Boilers Project is to reduce Greenhouse Gas Emissions (GHG), as well as emissions of total suspended particulates, sulfur dioxide and nitrogen oxides through: a) the development of affordable energy
The Boiler Efficiency Institute provides maintenance and operation manuals for boilers and boiler control systems. To encourage quality operations and maintenance, building engineers can also refer to ASHRAE/ACCA Standard 180: Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems.
For this reason, testing the energy efficiency of your industrial boiler should be part of routine maintenance. Typically, the best way to test the efficiency of a steam boiler is by installing a set of meters to measure each part of the process.
