APPLICATION OF CONDENSATION ECONOMIZERS ON GAS ENERGY AND WATER HEATING BOILERS

POWER ENGINEERING: economics, technique, ecology, 2022
The provision of increasing the level of safety of the power plant in case of emergency shutdown, as well as increasing the efficiency of the boiler is considered. Disconnection of CHP from the grid entails, first of all, the threat of cessation of heat water supply to the city and, as a consequence, human and material losses.

Heat flux distribution on circulating fluidized bed boiler water wall

Frontiers of Energy and Power Engineering in China, 2008
The future of circulating fluidized bed (CFB) combustion technology is in raising the steam parameters to supercritical levels. Understanding the heat flux distribution on the water wall is one of the most important issues in the design and operation of supercritical pressure CFB boilers.

Waste Heat Recovery System Using Coal-Fired Boiler Flue Gas to Heat Heating Network Return Water

2013
At present, exhaust flue gas temperature of coal-fired boiler is generally above 120 °C, while the temperature of boiler burning high sulfur coal may be higher in China. Meanwhile, the boiler burns large amount of fuel to heat the heating network return water to the supply temperature.

ESTIMATION OF THE WATER-MASS-FLOW THROUGH A CENTRAL HEATING BOILER

IFAC Proceedings Volumes, 2002
Abstract Conventional central heating systems in German buildings are hot-water heating systems. These systems consist of a boiler and radiators or heating coils in the floor. A heating characteristic maps the current outdoor temperature to the set-point of the boiler outlet-temperature.
