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、的装卸及搬运过程中需注意以下事项:起吊设备的起吊能力应与提吊的热风炉重量相匹配。热风炉上带有不能用于起吊标示的吊耳不能用作起吊用应合理选择钢丝绳的长度,避免因钢丝绳长度不合适,导致炉体划伤。在装卸及搬运过程中必须确保热风炉不受任何损伤。
2、维护空间的预留安装热风炉时,需确保在热风炉四周留有足够的维护空间。
3、燃气热风炉基础、底座的设置及注意事项热风炉本体须安装在高于地坪100-150mm的基础上、须事先同热风炉制造公司技术人员进行确认,按照基础图纸进行施工。基础上须留出地脚螺栓预埋孔。基础须能承受热风炉及所保有水量的最大重量。安装底座时,须先进行定位。定位后调整到底座两对角线的长度相同,然后在拧紧全部固定螺栓。底座的安装参照基准线标示进行。
4、一般注意事项注意不要将热风炉以及附属品过于倾斜和加以冲击。热风炉周边不可放置可燃物。不要用油和水等弄脏热风炉热风炉一般应装在单独的热风炉房内,新建的燃气不应与住宅相连。热风炉房不得与甲、乙类及使用可燃液的丙类火灾危险性房间相连。若与其它生产厂房相连接时,应用防火墙隔开。
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.
即机械未完整熄灭热损失、灰渣物理热损失均为零;在热风炉正常运转的状况下,化学未完整熄灭热损失,接近于零;散热损失,和热风炉的炉型及维护构造有关,关于燃气热风炉,普通都是小型的快装炉,表面面积较小,并采用了高热阻及封锁的外罩壳作为保温层,也不大,并且随热风炉容量的增大而减少。因而,燃气热风炉的最为主要的热损失是排烟热损失。
所谓的排烟热损失是指烟气分开末级受热面带走的热量,它主要决议于排烟温度。降低排烟温度可显著地减少排烟热损失。而如今的燃气热风炉的排烟温度普通在200-250℃之间,这局部热量随烟气进入大气后成为废热。降低排烟温度可减少这局部热最的损失,并可完成对这局部热量的局部回收。因而,降低热风炉的排烟温度是必要的。
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.
