DO YOU KNOW WHAT HAPPENS WHEN WE USE BOILER AT HIGHER ALTITUDE

• A boiler designed to generate 5000 kg/hr steam for & at 100 ⁰C at mean sea level will not give the same quantity of steam if shifted to an elevated place. It will give less steam.
• Due to decreased air density at higher altitude the boiler will consume same volume of air but will not consume same mass of air.
• This results in less fuel consumption & less steam generation rate.
• Due to reduction of mass flow of gases through tubes of boiler, convective heat transfer also decreases which further results in reduced evaporation rates.
