Boilers can operate on a variety of fuels including natural gas, propane or fuel oil. Boilers can be used to produce hot water or steam. Process heaters are used to heat a working fluid other than water where flue gas does not come into contact with the working fluid. Common techniques for controlling emissions include the use of low NOx

Oct 30, 2019 · The selection of fuel to burn in the boiler is the first opportunity to reduce flue gas contaminants. For example, natural gas burns cleaner than fuel oil, medical waste, or biomass and produces the least amount of pollutants in its flue gas. Natural gas is considered a low-nitrogen fuel and yields very little NOx as a by-product of combustion.

stiffer air pollution control regulations. The result: in 1990, Congress passed its most comprehensive piece of environmental legislation, the Clean Air Act Amendments (CAAA). The Boiler Emissions Reference Guide is a multi-purpose tool, which is intended to give you a clearer understanding of how industrial boilers fit into the clean air equation.
Get a QuoteThe twinning of biomass boilers into one flue should only be designed and installed by a competent chimney specialist in accordance with BSEN 13384-2:2003+A1:2009, and with the approval of the boiler and flue manufacturers. The installation must also be notified to the Local Authority Building Control Officer for approval.

Dec 17, 2019 · Reasons for Increasing Exhaust Gas Temperature of Boiler. December 17, 2019. The heat loss of exhaust gas is the biggest one of all the heat losses of the boiler. Generally, the lost heat is 6% of the heat input into the boiler furnace. The heat loss of exhaust gas increases by 0.5% when the temperature of exhaust gas increases by 12-15%.

Whenever the boiler plant is shut down, inspect the fireside surface for a buildup of soot and the waterside surface for a buildup of scale, both of which can increase flue gas temperatures and heat loss and interfere with heat exchange. Treat boiler feedwater as required to reduce deposits. Use soot blowers, brushes, or manual lances as required.
