Parametric Identification of the Reheater of a Power-Plant

Feb 19, 2015 · Existing methods of controlling the temperature of superheated steam in a power-plant boiler are analyzed. Judging from the quality indices that are obtained, the optimum control method for this purpose was determined to be the injection of natural condensate. It is shown that the temperature regime of the reheater of the boiler depends on the organization of the injection operation. A

Chapter Liming Rules and Regulations for Boiler and

(22)(24) Hot Water Heating Boiler — A boiler in which no steam is generated, from which hot water is circulated for heating purposes and then returned to the boiler, and which operates at a pressure not exceeding 160 psig and/or a temperature of 250 degrees Fahrenheit at or near the boiler outlet.

Dec 01, 2000 · This paper describes the application of the MUSMAR predictive adaptive controller to the regulation of super heated steam temperature in a commercial boiler. The boiler considered produces 150 t / h of steam at maximum load, used both for electric energy production in a turbine and industrial use. The combination of predictive and adaptive techniques, relying on multiple models redundantly …

Regulations for boiler-free steam generators

Safe management of industrial steam and hot water boilers. boilers now operate at the pressure of the incoming cold water mains, this is still far below the normal operating pressure of steam-raising boilers. This leaflet applies to steam and high temperature hot water boiler plant (operating above 0.5 bar pressure and a. Learn More

California Code of Regulations, Title 8, Section 753

Automatically Controlled Boiler: A boiler equipped with devices to maintain the burner firing conditions, the pressure and/or temperature, and the water level or water content within the predetermined limits without manual manipulation. Boiler: A fired or unfired pressure vessel used to generate steam pressure by the application of heat.
