Modeling of a steam boiler operation using the boiler

The steam mass flow rate m ˙ e v c is calculated from the energy balance equation for the boiler evaporator and m ˙ e v c is a function of the water-wall heat efficiency ψ. The water-wall heat efficiency ψ can be determined by multiplying the fouling coefficient of the chamber furnace heating surfaces ζ and the water-wall shape factor x

Reheaters and Superheaters - Vallourec

Reheaters and superheaters are a set of tubes located in the boiler. Steam from the water walls passes to the superheaters where it is heated above its saturation temperature until the maximum required operating temperature is achieved. The superheated steam then flows through the main steam piping to the high-pressure turbine.

What is a Boiler Deaerator and How Does It Operate? - MPC

Boiler deaerators commonly are used to remove oxygen and other gases from the water that feeds into boilers that generate steam. Deaerators are useful because they remove the gases that attach to the metallic components of the steam system and cause corrosion by forming oxides, or rust.

Steam engines, however, cannot take the advantage of a very low vacuum in the condenser because they are intermittent (non-continuous) flow machines and have to force the expanded steam out of the cylinder through restricted exhaust ports and passages.

What is the function of economizer in steam power plant

A common application of economizers in steam power plant is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
