首先让我们认识热风炉的一些产品知识：要进步燃气热风炉的热效率，就要减少各种热损失。关于燃气热风炉，由于气体燃料熄灭后简直没有灰分，更没有固体、液体燃料的机械不完整熄灭现象。 燃气的装卸和安装很关键，是影响供暖及寿命最重要的一个环节，小编给大家整理一份有关装卸和安装的注意事项。具体内容如下： First of all, let's know some product knowledge of the hot stove: to improve the thermal efficiency of the gas hot stove, we must reduce all kinds of heat loss. As for the gas hot stove, there is no ash content after the gas fuel is extinguished, and there is no mechanical quenching phenomenon of solid and liquid fuels. Gas loading and unloading and installation is very important, is the most important part of the impact of heating and life, a small editor to arrange a part of the handling and installation of attention. The specific contents are as follows:
1. Attention should be paid to the following items during loading and unloading: the lifting capacity of lifting equipment should match the weight of the hot blast stove. The hanging ear, which can not be used to mark the hoisting, should not be used as a lifting device to choose the length of the wire rope reasonably, so as to avoid the injury of the furnace body because the length of the wire rope is not suitable. Ensure that the stove is free from any damage during handling and handling.
2, the maintenance of space for the installation of hot blast stove, we need to ensure that there are enough maintenance space around the hot stove.
3. Setting and attention of the base and base of the gas hot stove, the hot air furnace must be installed on the basis of the floor 100-150mm and must be confirmed in advance with the technical personnel of the hot air stove manufacturing company, and the construction will be carried out according to the basic drawings. The anchor bolt should be retained on the basis of the hole. The foundation must be able to withstand the maximum weight of the hot stove and the amount of water it holds. When the base is installed, the positioning must be carried out first. After positioning, adjust the length of the two diagonal of the bottom seat, and then tighten all the fixed bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions should not be too inclined and impacted on hot stove and accessories. No combustible materials can be placed around the hot stove. Do not dirty the hot stove with oil and water. The hot stove should be installed in a separate hot blast stove room. The new gas should not be connected to the house. Hot blast stove rooms must not be connected to class A, B and combustible liquids. If it is connected with other production plants, the firewall should be separated.
In the condition of the normal operation of the hot blast stove, the heat loss, close to zero, and the loss of heat, are related to the furnace type and maintenance structure of the hot blast stove, and the gas hot blast furnace is usually small fast loading furnace with small surface area and adopted. The outer shell with high thermal resistance and blockade is not big as insulation layer, and it decreases with increasing capacity of hot blast stove. Therefore, the most important heat loss of gas fired hot stove is exhaust heat loss.
The so-called exhaust heat loss refers to the heat that the flue gas separates from the last heating surface. It mainly determines the exhaust gas temperature. Reducing exhaust gas temperature can significantly reduce exhaust heat loss. Nowadays, the exhaust gas temperature of the gas-fired hot blast stove is usually between 200-250 degrees. This local heat comes into the atmosphere with flue gas and becomes a waste heat. Reducing the exhaust gas temperature can reduce the most local heat loss, and can achieve partial recovery of the local heat. Therefore, it is necessary to reduce the exhaust temperature of hot blast stove.
