Faqs Of Economisers
What is a boiler economiser? +
A boiler economiser is a heat exchanger that heats feedwater before it enters the boiler steam drum, using thermal energy recovered from hot flue gases.
How much efficiency does an economiser add to a boiler? +
Generally, every 6°C rise in feedwater temperature through an economiser saves about 1% of fuel and improves overall boiler efficiency.
What are the main benefits of using an economiser? +
It reduces fuel consumption, lowers thermal shock to boiler drums, reduces exhaust gas temperatures, and helps lower greenhouse gas emissions.
What causes corrosion in boiler economisers? +
Internal corrosion is caused by dissolved oxygen in feedwater, while external corrosion is caused by sulfuric acid condensation from flue gases (cold-end corrosion).
What industries install boiler economisers? +
Process industries like textiles, chemicals, food processing, sugar mills, paper mills, and power generation facilities using steam boilers.
