  • The Importance of Operating with Proper Furnace Draft

    Aug 26, 2020 · Most power plant boilers have balanced draft furnaces. This means there is a fan (or fans) that supplies combustion air to the boiler furnace, known as a forced draft fan, and another fan that pulls the exhaust gases (flue gas) from the boiler furnace 1, known as an induced draft Fan. These fans work together to maintain pressure (or draft) in the furnace slightly less than atmospheric Learn More

  • Gas Boiler - an overview | ScienceDirect Topics

    T. Fleiter, P. Plötz, in Encyclopedia of Energy, Natural Resource, and Environmental Economics, 2013 Condensing Gas Boilers. Condensing gas boilers are designed to make use of the latent heat contained in their water vapor flue gas, which results in a conversion efficiency that is about 20% higher than noncondensing gas boilers.. In the Netherlands, condensing gas boilers entered the market Learn More

  • Control Engineering | Power Control: Advanced Process Control

    Jun 20, 2011 · The objective of the base layer control is to stabilize the process using PI feedback control loops. The FD dampers control the forced draft via pressure PI controllers. Sticktion (mainly from the coal ash in the boiler house) has a tendency to accumulate on the final control elements of the FD dampers, causing pressure cycles.Learn More

  • how to control boiler burners

    Excess air can also produce excess NO x in some burners. So we want to control O 2 at its ideal amount for the load. The burner manufacturer should provide an O 2 trim SP curve – this should be plugged into a PWC with the output running through a bias station (always in auto!) to set the SP of the O 2 trim PID loop.Learn More
