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.

鍋爐的額定功率和燃?xì)獾臒嶂?。利用公式：燃?xì)饬?鍋爐的額定功率*時(shí)間/燃?xì)鉄嶂?鍋爐效率。

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.

確定燃?xì)忮仩t的規(guī)格，如1噸、2噸等等，其次是鍋爐受熱面熱阻，根據(jù)這兩個(gè)條件我們可以確定燃?xì)忮仩t的熱損失，通過得到的熱損失數(shù)值，可以進(jìn)一步得到熱效率，通過熱效率，在根據(jù)總?cè)萘砍艘詤?shù)得出總熱焓值，然后用燃?xì)獾目偀犰手党艘詿嵝?，得到的?shù)值在除以介質(zhì)的總熱焓值，這個(gè)數(shù)值就是我們需要的燃?xì)忮仩t單位時(shí)間內(nèi)的耗氣量信息。

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.

根據(jù)熱量公式來進(jìn)行計(jì)算。

Calculate according to the heat formula.

2噸燃?xì)忮仩t功率為1.4MW（1400kW），燃料的熱值為35.53MJ/Nm3(百度得知）,通常燃?xì)忮仩t熱值利用率為88%—90%之間。所以我們可以得出公式為：燃?xì)忮仩t耗氣量（每小時(shí)）=燃?xì)忮仩t功/鍋爐率*時(shí)間/燃料熱值/燃?xì)忮仩t熱值利用率=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。
