  • US4659305A - Flue gas recirculation system for fire tube

    A flue gas recirculation system for fire tube boilers includes a duct connected to the boiler gas discharge stack and to a fan. Another duct couples the fan to a specially designed burner in the boiler. Recirculated flue gas is injected downstream of the fuel/air mixture in the burner and cools the flame leading to substantially reduce the NO x content in the boiler stack emissions.Learn More

  • Boiler Circulation Problems Troubleshooting #1 Step-by-Step

    Jun 12, 2019 · Under the subcritical pressure, the natural circulation boiler with the flue gas parameter of 16.6~18.2 MPa and the working pressure of the drum reaches 18.6~20.6 MPa, and the natural circulation still has sufficient water circulation driving force to achieve safe and reliable operation.Learn More

  • Central Heating Circulating Pump: Troubleshooting | Living

    May 13, 2020 · A circulating pump is a water pump that moves hot water around your heating system. The water travels from your boiler through to the pipes that feed your radiators, towel rails, and hot water cylinder. The water then flows back to the boiler to maintain a constant flow of heated water around your home.Learn More

  • Challenges when Converting Coal-Fired Boilers to Natural Gas

    The natural gas supply system to the boiler utilized a single flow control valve for all the burners. The plant operation wanted the ability to bias heat input in between different levels of burners, but the single control did not allow it. Furthermore, when bringing individual burners in Learn More

  • Plant Engineering | GAS TECHNOLOGY: Boiler NOx Emissions

    In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called "Ultra-Low NOx" (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas.Learn More
