Simple calculation of steam boiler
Steam boiler is to convert the energy of fuel into steam, and the steam produced to meet a certain temperature, a certain pressure. For example, the nameplate of the steam boiler says that the thermal power of the boiler is 1.4MW. In our usual words, it is a 2ton boiler, because 0.7MW=1ton. And a 1ton steam boiler means a steam boiler can turn a ton of water into steam per hour.
And how much for 1ton steam boiler burning coal is calculated according to actual situation.
For example a 1ton steam boiler, the 1ton steam and water is heated to 180 degrees 12 degrees, how much is in coal consumption.
Assumptions used are of standard coal, coal of standard coal is said to receive low calorific value of 29270 kj/Kg (29270 kj/Kg = 7000 calories) fuel become of standard coal. The specific heat capacity of water is calculated at 4.2 CAL /Kg per Celsius degree. 12 degrees of water enthalpy is 50.38 KJ/Kg, 180 degrees of water enthalpy value is 2777.74 KJ/Kg, then one ton of water heated to 180 degrees 1 ton of 12 degrees of calorific value of the steam needed for 1 * 1000 * 4.2 = 649371.429 (2777.74 50.38)/calories, so you need to BiaoMei 649371.429/7000000 = 0.093 tons. However, this figure is obtained without considering the heat loss in the process of heat transfer by doing work. Generally, the heat transfer efficiency of the whole process can be set as 75% in rough calculation, so the standard coal consumption is 0.093/75%=0.124 tons.
According to calculations, it takes about 0.124 ton of standard coal to heat a ton of water at 12 degrees Celsius to steam at 180 degrees Celsius. Using conventional coal at 5,000 calories, it would need about 0.1736 tons. And the calculation here is very idealistic, the enthalpy of the steam is saturated, and the steam is not superheated.
Advantages of steam boiler
Steam boiler is widely used in food, chemical, pharmaceutical, paper making, printing and dyeing, textile, clothing, building materials, heating and bathing industries, the industry is different, the demand for steam and temperature is different, the emphasis of auxiliary machine configuration is also different.
According to the different medium, the steam boiler can be divided into fuel gas steam boiler, biomass steam boiler, coal steam. Boilers, etc., due to the introduction of domestic coal to gas and low nitrogen transformation regulations, gas-fired steam boilers have become the mainstream products, widely used in various production industries and fields.
Gas steam boiler has high thermal efficiency and low operating cost. Safety; The types of gas steam boiler include gas steam boiler, gas condensing boiler and gas low nitrogen boiler.
