Boiler auxiliary types of equipment usually consist of economizer, deaerator, condensate, damper. These auxiliary types of equipment would vary according to the project.
The flue gas from the boilers of industrial boilers or processes has a large amount of thermal energy. Economists use this energy in the flue gas to save energy by increasing the temperature of the water/air used in the boiler or anywhere in the business. Depending on the boiler flue gas outlet temperature and the fuel type, the efficiency of the boiler or plant is increased between 3% and 8,5%.
The deaerator is only part of a large boiler feed water system. Boiler feedwater usually contains two harmful dissolved gases; oxygen and carbon dioxide. The purpose of deaeration is to remove these gases before they are liberated in the boiler. This reduces corrosion in the boiler, steam lines, condensate lines, and heat transfer equipment.
It is the tank where the condensate returning from the operation and the steam boiler room is collected and the fresh (make-up) water that decreases according to the set level value is added and stored for pumping into the deaerator.
The transported condensate is injected into the tank with a specially designed condensate distribution system so that it can penetrate homogeneously and safely throughout the tank. In this way, flash steam is minimized.
Dampers that can be controlled proportionally or on/off according to the requirements of the process in gas flow lines are generally manufactured as two-way or three-way. It is generally used for flow routing to protect systems from overloads or to provide services in a healthy way. In order not to disturb the flow in the lines, it should be produced from the appropriate material in the appropriate diameter and according to the chemical properties of the fluid. If desired, 100% sealing can be provided.
