The capacity of a hot water boiler cannot be expressed in t/h (incorrect)

The capacity of hot water boilers cannot be expressed in t/h() ×

Wrong,×~~~~~~~~~~~~~~~~

The capacity of hot water boilers cannot be expressed in t/h (correct)

The capacity of hot water boilers cannot be expressed in t/h (√)

The capacity of hot water boilers cannot be expressed in t/h (correct)

The capacity of hot water boilers cannot be expressed in t/h (correct)

The capacity of hot water boilers cannot be expressed in t/h (√)

The capacity of hot water boilers cannot be expressed in t/h. The capacity of steam boilers is indicated by their evaporation rate, with the unit being t/h (commonly referred to as steam tons). The capacity of a hot water boiler is expressed in terms of heat power (formerly known as heating capacity), with the unit being MW. The capacity unit for hot water boilers should not be converted to that of steam boilers; in other words, the capacity of hot water boilers cannot be expressed in t/h. On the contrary, when calculating the total capacity of various boilers, thermal power in MW is commonly used internationally. In other words, the capacity of steam boilers also needs to be converted into MW for statistics. Strictly speaking, when the evaporation capacity of steam boilers is the same, their steam enthalpy varies depending on the rated pressure and temperature ； In other words, when the evaporation rate is the same, steam boilers with different rated pressures and temperatures have different thermal powers, but the difference is not significant. For ease of statistics, 1 t/h is uniformly converted to 0.7 MW.
