·燃气锅炉的热效率核算

时间:2017-02-22   作者:
下面锅炉网的小编跟大家介绍燃气锅炉的热效率核算  的热效率核算这是一个专业性的问题,燃气锅炉的热效率是单位时刻内锅炉有用运用热量占锅炉输入热量的百分比,对燃气锅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。燃气锅炉的热效率核算:Q1————-单位时刻内锅炉对外供汽在炉内吸收热量的总焓  Q1= 单位时刻内锅炉对外供汽总焓 - 一起刻内锅炉给水的总焓   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锅炉的热效率 = 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。 当前国产锅炉规划最高燃气锅炉的热效率最高达90%以上。 100t/h锅炉热丢失假如指的是燃气锅炉的话约在10%——-20%之间 的费用是燃煤锅炉的一半,而运转费用却是燃煤锅炉的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。挑选燃气锅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,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,由于燃气锅炉是全自动的,而燃煤锅炉需求 杂乱的操作和对比大的保护费用,全体下 来大概比燃煤锅炉运转本钱高60%-70%

英文:Below the small series with the boiler network to introduce gas boiler heat efficiency calculation This is a professional problem, the thermal efficiency of gas boiler is the percentage of boiler heat input, which is the percentage of the corresponding input heat in the gas boiler, which is used in the heat. Calculation of the thermal efficiency of gas boiler: the total enthalpy of absorbing heat from outside of the boiler in Q1————- unit Q1= unit time internal boiler steam enthalpy - the total enthalpy of boiler feed water The total enthalpy of Q2———- unit heat consumption of gas occurrence time Q2 = per cubic meter of burning gas thoroughly burned exothermic total enthalpy * time internal combustion gas volume of the boiler thermal efficiency = Q1 / Q2 * 100% Note, the unit of the above mentioned refers to the time period in which the measurement of gas, water, gas and the same unit. At present, the heat efficiency of the boiler in the boiler is the highest of 90%. 100t/h boiler heat loss if the gas boiler is about 10%——-20% The cost of a gas boiler is half the boiler, while the operating cost is 2 times the coal boiler, a ton of steam demand is 80 cubic meters of natural gas, while the coal is not more than 0.185 tons, the economy will be considered. Selection of gas boiler real specific conditions last ditch selection. And the gas is better in performance. In principle, they are heat conversion equipment, the difference is that the burning and thermal efficiency, coal boiler heat efficiency is usually around 80% and gas boiler heat efficiency in more than 90%, there are coal preparation and so on, and the gas only need to burn so simple, and the need for the gas boiler and the large cost of the operation and contrast, all the more than coal-fired boiler operation cost 60%-70% Above is the boiler network of small series for everyone to introduce the thermal efficiency of gas boiler, gas boiler heat loss, if you have what need to consult us, we will be one one for you to answer. 文章来源:
