Hot blast stove is a thermal power machine, which has been widely used in our country since the end of 1970s. It has become a replacement product of electric heat source and traditional steam power heat source in many industries. It can be divided into coal, oil, gas stove and so on according to the type of fuel. Among them, coal and gas are the most common, so which of the two is better? Which of the natural gas-fired hot stoves or coal-fired hot stoves has a better cost-effective and more cost-effective? Next, the hot stove manufacturer will discuss which hot stove is more cost-effective from the following aspects. 第一个：首先是贩卖成都收账本钱价钱：因为燃气热风炉在技巧和配套辅机上显著优先于燃煤热风炉，而且配有公用收账燃气燃烧机，不说其余，单此一个燃烧机成都找人公司价钱就把这个装备本钱给拉开了。一般来说：异样吨位的蒸气热风炉，燃气汽锅要比燃煤热风炉价钱高上约25%阁下，如许看来燃气蒸气热风炉的价钱是要比燃煤热风炉略高些。
Firstly, the cost of selling is the first one: because the gas hot-blast stove is superior to the coal-fired hot-blast stove in skills and auxiliary equipment, and equipped with a common gas burner, not to mention the rest, the cost of this equipment is pulled aside by the price of a single burner. Generally speaking, the price of gas-fired hot stove is about 25% higher than that of coal-fired hot stove, so it seems that the price of gas-fired hot stove is slightly higher than that of coal-fired hot stove.
The second is the cost of equipment arrangement of hot blast stove. The equipment cost is mainly invested in the hot blast stove house and steam hot blast stove pipeline. Gas hot blast stove is fully automatic control, because the response auxiliary equipment is more, and has automatic alarm, automatic protection and yield. When connected to the natural gas pipeline, the burner will automatically supply gas, which can effectively squander the cost of personnel. Coal-fired hot-blast stove because of the need for coal and other manual work order, so that personnel wages will be invested more capital, while coal-fired steam hot-blast stove in hot-blast stove room to create more funds. So the cost of coal-fired steam stove is slightly higher.
Third, we should consider the cost of fuel. According to the inspection, in some undeveloped areas, coal-fired hot stoves will be more popular, because the proportion of one-time investment in coal-fired steam cookers is small, and the coal-fired hot stoves themselves have great control. But in some developed areas, people's thinking will be different. The consumption of coal-fired hot blast stoves will also lead to net pollution of the environment, such as waste residue, waste gas and waste water, which will bring persecution to people's long-term livelihood. The gas hot blast stove has the advantages of small floor area and less emission pollution, and the installation cost of the hot blast stove room is not the highest. After the use of natural gas, the fuel price decreases and the operating cost is lower than that of the oil-fired hot blast stove.
Fourth: Economic Benefit: Coal is used in coal-fired hot-water hot-blast stove. The calorific value of coal is about 5500 Kcal/Kg (calculated according to standard coal). Its market price is 460 yuan per ton (the price of coal is rising constantly, and the purchasing and selling channels are not smooth. 10 t hot water stove consumes 0.2 tons of coal per ton of hot water and the price is 92 yuan. The calorific value of natural gas is 8000 kcal/Nm3, and the price of natural gas is 2.0 yuan per cubic meter. The price is 160 yuan based on the consumption of natural gas and 80 Nm3 per ton of hot water.
