     燃气热风炉的热效率核算这是一个专业性的问题,燃气热风炉的热效率是单位时刻内热风炉有用运用热量占热风炉输入热量的百分比,对燃气热风炉则是每标准立方米(气体燃料)所对应的输入热量中 有用运用热量的所占百分比,一口气说这么长蒙了吧。燃气热风炉的热效率核算:Q1————-单位时刻内热风炉对外供汽在炉内吸收热量的总焓Q1= 单位时刻内热风炉对外供汽总焓 - 一起刻内热风炉给水的总焓 

     Q2———- 单位时刻内耗费燃气发生热能的总焓   

     Q2 = 每立方米燃用气体彻底焚烧放热总焓 * 单位时刻内燃用气体全体积热风炉的热效率 = Q1/Q2 * 100%

    注;以上说的单位时刻指的是在计量汽,水,燃气同一单位时刻段。

    当前国产热风炉规划最高燃气热风炉的热效率最高达90%以上。

    100t/h热风炉热丢失假如指的是燃气热风炉的话约在10%——-20%之间

    燃气热风炉的费用是燃煤热风炉的一半,而运转费用却是燃煤热风炉的2倍,一吨蒸汽需求焚烧天然气80立方左右,而燃煤不超越0.185吨,这个经济账都会 算。挑选燃气热风炉真实特定的条件下 不得已而为之的挑选。还有在性能上燃气好于燃煤。在原理上,它们都是热变换设备,差异即是在于焚烧和热效率上,燃煤热风炉的热效率通常在80%左右而燃气锅 炉的热效率在90%以上,还有燃煤制备等等,而燃气只需求焚烧器这么简略,由于燃气热风炉是全自动的,而燃煤热风炉需求 杂乱的操作和对比大的保护费用,全体下 来大概比燃煤热风炉运转本钱高60%-70%

    下面热风炉网的小编跟大家介绍燃气热风炉的热效率核算
    The Xiaobian of the hot-air stove net introduces the thermal efficiency calculation of the gas hot stove. 燃气热风炉的热效率核算这是一个专业性的问题,燃气热风炉的热效率是单位时刻内热风炉有用运用热量占热风炉输入热量的百分比,对燃气热风炉则是每标准立方米(气体燃料)所对应的输入热量中 有用运用热量的所占百分比,一口气说这么长蒙了吧。燃气热风炉的热效率核算:Q1————-单位时刻内热风炉对外供汽在炉内吸收热量的总焓
    It is a professional problem to calculate the thermal efficiency of gas-fired hot-blast stove. The thermal efficiency of gas-fired hot-blast stove is the percentage of the useful heat used by the hot-blast stove to the input heat of the hot-blast stove in a unit time, and for gas-fired hot-blast stove, the percentage of the useful heat used in the input heat corresponding to each standard cubic meter (gas fuel). That's a long way to go. Calculation of Thermal Efficiency of Gas-fired Hot-blast Furnace: Q1-- Total Enthalpy of Heat Absorbed by Steam Supplied to Outside Hot-blast Furnace in Unit Time

    Q1= 单位时刻内热风炉对外供汽总焓 - 一起刻内热风炉给水的总焓
    The total enthalpy of external heat supply of hot blast stove in Q1= unit time, together with the total enthalpy of water supply in hot blast furnace.

    Q2———- 单位时刻内耗费燃气发生热能的总焓
    Q2 - - total enthalpy of heat generated by unit time internal consumption gas

    Q2 = 每立方米燃用气体彻底焚烧放热总焓 * 单位时刻内燃用气体全体积热风炉的热效率 = Q1/Q2 * 100%
    Q2 = Total enthalpy of heat release per cubic metre of burned gas thoroughly incinerated * Thermal efficiency per unit time of all accumulated heat stove of burned gas for internal combustion = Q1/Q2 * 100%

    注;以上说的单位时刻指的是在计量汽,水,燃气同一单位时刻段。
    Note: the units mentioned above refer to the same unit time of metering steam, water and gas.

    当前国产热风炉规划最高燃气热风炉的热效率最高达90%以上。
    At present, the highest efficiency of the domestic hot blast stove is above 90%.

    100t/h热风炉热丢失假如指的是燃气热风炉的话约在10%——-20%之间
    100t/h hot blast stove heat loss if it refers to the gas stove, about 10% - -20%.

    燃气热风炉的费用是燃煤热风炉的一半,而运转费用却是燃煤热风炉的2倍,一吨蒸汽需求焚烧天然气80立方左右,而燃煤不超越0.185吨,这个经济账都会 算。挑选燃气热风炉真实特定的条件下 不得已而为之的挑选。还有在性能上燃气好于燃煤。在原理上,它们都是热变换设备,差异即是在于焚烧和热效率上,燃煤热风炉的热效率通常在80%左右而燃气锅 炉的热效率在90%以上,还有燃煤制备等等,而燃气只需求焚烧器这么简略,由于燃气热风炉是全自动的,而燃煤热风炉需求 杂乱的操作和对比大的保护费用,全体下 来大概比燃煤热风炉运转本钱高60%-70%
    Gas-fired stoves cost half as much as coal-fired stoves, and the operating cost is twice as much as coal-fired stoves. A ton of steam requires about 80 cubic metres of natural gas to be burned, while coal does not exceed 0.185 tons. This economic account will be counted. The selection of gas hot stove must be chosen under the specific conditions. And in terms of performance, gas is better than coal. In principle, they are all heat transfer equipment, the difference is in the incineration and thermal efficiency, the thermal efficiency of coal-fired hot blast stove is usually about 80%, the thermal efficiency of gas boiler is more than 90%, and the coal preparation and so on, and the gas only needs the burner so simple, because the gas hot blast stove is fully automatic, and the coal-fired heat The stove requires a messy operation and a comparatively large protection cost, which is about 60% - 70% higher than the operating cost of the coal-fired hot blast stove
