燃煤热风炉与燃油燃气热风炉构造的区别

燃煤热风炉与燃油燃气热风炉构造的区别[1]、炉膛受热面也有很大不同,由于比较复杂,在这就不在详细解说。[2]、燃油热风炉所配燃烧器必须有油物化器,而燃气热风炉所配燃烧器则无需物化器。[3]、燃油热风炉使用燃烧器,燃煤热风炉中,有固定炉排、煤粉燃烧器以及沸腾炉等燃烧方法。[4]、燃油热风炉一般没有燃烬装置,燃烧的废气通过烟囱排放。而燃煤热风炉一般都有灰斗、捞渣机等除灰设施。

The difference of structure between coal-fired hot blast stove and oil-fired hot blast stove [1] and the heating surface of furnace are also very different. Because of the complexity, it is not explained in detail here. [2] The burner of the oil-fired hot blast stove must have an oil physicochemical device, while the burner of the gas-fired hot blast stove does not need a physicochemical device. [3] Oil-fired hot-blast stove uses burner. In coal-fired hot-blast stove, there are fixed grate, pulverized coal burner and fluidized bed furnace combustion methods. [4] and oil fired hot blast stoves generally do not burn out, and the exhaust gas is discharged through the chimney. Generally, there are ash handling facilities such as ash hopper and slag remover. [5]、燃油热风炉与燃气热风炉,就本体结构而言没有多大的区别,只是由于燃料热值不同,将受热面作了相应的调整。即燃油热风炉辐射受热面积较大,而燃气热风炉则是将对流受热面设计的大些。

[5] There is not much difference between oil-fired hot blast stove and gas-fired hot blast stove in terms of body structure, but because of the different calorific value of fuel, the heating surface has been adjusted accordingly. That is to say, the radiation heating area of oil-fired hot stove is larger, while that of gas-fired hot stove is larger.

[6]、燃油热风炉,必须配置一套较复杂的供油系统(特别是燃烧重油、渣油时),如油箱、油泵、过滤器加热管道等,必须占据一定的空间,而燃气热风炉,则无需配置储气装置。只需将用气管道接入供气网即可,当然,在管道上还需设置调压装置及电磁阀、缓冲阀等附件,以确保热风炉安全运行。

[6] Oil-fired hot blast stove must be equipped with a more complex oil supply system (especially when burning heavy oil and residue), such as fuel tank, oil pump, filter heating pipeline, etc. It must occupy a certain space, while gas-fired hot blast stove does not need to be equipped with gas storage device. It is only necessary to connect the gas pipeline to the gas supply network. Of course, pressure regulating devices, solenoid valves, buffer valves and other accessories should be installed on the pipeline to ensure the safe operation of the hot blast stove.

目前,我国的电站热风炉中一般为燃煤热风炉,少有燃油燃气热风炉。只有在特殊场合如有重油和渣油的地方有少量燃油热风炉使用。还有,许多采暖用的中小型热风炉采用燃油燃气热风炉,以便于环保达标。

At present, China's power plant hot blast stove is usually a coal-fired hot stove, and there are few oil and gas hot-air stoves. Only on special occasions, where there are heavy oil and residual oil, are there a small number of oil fired hot blast stoves. In addition, many small and medium sized hot air stoves for heating use fuel gas hot-air stove for environmental protection.
