Lee2∗ This article provides an overview of fossil-fuel power plant (FFPP) configura-tion, design and especially, the control technology, both the conventional and the advanced technologies.

how to control sio2 in steam at power plant boiler. Electric Heated Steam Boiler. control comprises a series of devices on a boiler developed to satisfy steam demands automatically and economically by controlling furnace combustion rates through adjustments of the burning components while maintaining a constant set point (such as a fixed but adjustable pressure or Analysis of Silica in

Experience has enabled the power industry to specify allowable concentrations of SiO2 in steam to avoid turbine damage. For a 180 bar operating pressure, in order to get a maximum of 5 ppb of SiO2 in the steam, the boiler water should not contain more than 100ppb of SiO2 if ideal boiler conditions are met.

steam cycle and the water treatment plant on modern power stations, is now a very well established practice. This enables careful control of the water chemistry to achieve peak efficiency and minimise downtime due to excessive boiler corrosion or scaling. Although silica has no significant corrosive effect which

Concentration control of silica in water chemical regime for natural circulation high pressure drum boiler unit of thermal power station ... (SiO2) in steam for pressure up to 22,000kPa and boiler ...

Lee2∗ This article provides an overview of fossil-fuel power plant (FFPP) configura-tion, design and especially, the control technology, both the conventional and the advanced technologies. First, a brief introduction of FFPP fundamentals and con-

Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler in modern power plant.

How do you control silica in boiler? ... Why silica increase in boiler drum inspite of 02ppm silca im boiler make up water? This is due to steam seperation the silica remains in the drum water.
