0.7MW of hot water boiler how many tons of water per hour
Known: 0.7MW hot water boiler, that is, rated heat equivalent to 600,000 kcal.
Different brands of boilers, thermal efficiency will be different; temperature rise of different natural production will be different.
Of course, this is based on the natural gas calorific value of 8600 kcal, the boiler thermal efficiency of 100% of the calculated value.
Then: 600000 (card) ÷ 40 (temperature rise) ÷ 1000 (kcal) = 15 tons
A ton of water temperature rise once, need heat 1000 kcal.
