    燃气锅炉的耗气量怎么计算?
    来源:http://shoesnewsusa.com 发布时(shi)间:2022-10-20

    计算一台燃气锅炉耗气量之前,先应该了解燃气锅炉的耗气量如何计算以及用气量受到哪些因素的影响。燃气锅炉的耗气量的决定因素有:锅炉受热面积,燃料热值,燃料纯度,锅炉对流受热面积,锅炉辐射受热面积以及司炉工的司炉技巧等。
    Before calculating the gas consumption of a gas-fired boiler, we should first understand how to calculate the gas consumption of the gas-fired boiler and what factors affect the gas consumption. The determinants of gas consumption of gas-fired boilers are: boiler heating area, fuel calorific value, fuel purity, boiler convective heating area, boiler radiant heating area and Stoker's skills.
    锅炉的额定功率和燃气的热值。利用公式:燃气量=锅炉的额定功率*时间/燃气热值/锅炉效率。
    Rated power of boiler and calorific value of gas. Use the formula: gas quantity = rated power of boiler * time / calorific value of gas / boiler efficiency.
    确定燃气锅炉的规格,如1吨、2吨等等,其次是锅炉受热面热阻,根据这两个条件J9九游会AG 可以确定燃气锅炉的热损失,通过得到的热损失数值,可以进一步得到热效率,通过热效率,在根据总容量乘以参数得出总热焓值,然后用燃气的总热焓值乘以热效率,得到的数值在除以介质的总热焓值,这个数值就是J9九游会AG 需要的燃气锅炉单位时间内的耗气量信息。
    Determine the specification of gas-fired boiler, such as 1t, 2T, etc., followed by the thermal resistance of boiler heating surface. According to these two conditions, we can determine the heat loss of gas-fired boiler. Through the obtained heat loss value, we can further obtain the thermal efficiency. Through the thermal efficiency, we can obtain the total enthalpy value according to the total capacity multiplied by the parameters, and then multiply the total enthalpy value of gas by the thermal efficiency, The obtained value is divided by the total enthalpy of the medium. This value is the gas consumption information of the gas boiler per unit time we need.
    根据热量公式来进行计算。
    Calculate according to the heat formula.
    2吨燃气锅炉功率为1.4MW(1400kW),燃料的热值为35.53MJ/Nm3(百度得知),通常燃气锅炉热值利用率为88%—90%之间。所以J9九游会AG 可以得出公式为:燃气锅炉耗气量(每小时)=燃气锅炉功/锅炉率*时间/燃料热值/燃气锅炉热值利用率=1.4MW*3600s/35.53MJ/Nm3/88%=161m³/h。
    The power of 2-ton gas-fired boiler is 1.4mw (1400kW), and the calorific value of fuel is 35.53mj/nm3 (known by Baidu). Generally, the calorific value utilization rate of gas-fired boiler is 88% - 90%. Therefore, we can get the formula: gas boiler gas consumption (per hour) = gas boiler work / boiler rate * time / fuel calorific value / gas boiler calorific value utilization rate = 1.4mw * 3600s / 35.53mj / Nm3 / 88% = 161m ³/ h。
