What does it mean to say boiler 300,000 kcal? What does it mean to say a boiler is half a ton? Are these two statements related?

Boiler 300,000 kcal refers to the boiler heat production of 300,000 kcal/hour, boiler half-ton refers to the boiler capacity of 0.5 tons per hour (t/h). The relationship is: in the case of a 1-ton boiler, for example, the boiler heat production is 600,000 calories per hour.

Hot water boiler continuous operation for a long time, in the rated return temperature, pressure and rated volume of circulating water, the effective heat per hour out of the water, known as the boiler's rated heat (output). With the symbol "Q", the unit is megawatt (MW). Hot water boiler to produce 0.7MW (600,000kcal / h) of heat, roughly equivalent to a steam boiler to produce 1t / h steam heat.

Where 1 calorie = 4.1868 joules, 1 large calorie = 1,000 calories = 4186.8 joules. 0.7MW = 0.7x360,000,000 joules/h = 0.7x360,000,000 ÷ 4186.8 kcal/h = 601,892 kcal/h, which is approximately equal to 600,000 kcal/h.

Expanded Information:

p>Relative signs of boiler capacity:

Signs of boiler capacity include rated boiler evaporation, maximum continuous boiler evaporation, etc.

The rated evaporation of boiler refers to the evaporation specified by the manufacturer in the model number under the rated steam parameter and feed water temperature, using the designed fuel, and under the condition that the thermal efficiency can be guaranteed, it is also the rated load of the boiler.

The boiler outlet main steam piping steam flow is called the main steam flow, i.e., evaporation, it is the boiler load size mark. In the rated main steam pressure and temperature conditions, the main steam flow and the load of the turbine generator set should have a one-to-one relationship between.
