Boiler Chemist Interview Questions and Answers

Boiler parameters values vary depending on the type of boiler and fuel used.

• Boiler pressure

• Boiler water level

• Fuel flow rate

• Air flow rate

• Steam temperature

• Steam pressure

• Feedwater temperature

• Blowdown rate

pH, TH, SiO2, Ir, Cl2, and conductivity are all important parameters in boiler chemistry.

• pH measures the acidity or basicity of a solution

• TH (total hardness) measures the amount of dissolved minerals in water

• SiO2 (silica) can cause scaling and corrosion in boilers

• Ir (iron) can cause rust and corrosion in boilers

• Cl2 (chlorine) can cause pitting and stress corrosion cracking in boilers

• Conductivity measures the ability of water to conduct electricity
