You will find that the characteristics of industrial boiler equipment are obvious. When designing industrial boilers, they should be regularly maintained. Vertical boilers have obvious characteristics Hunan Horizontal fuel oil steam generator The combustion part adopts a double-layer grate combustion chamber, which has fast temperature rise and pressure rise, reasonable overall layout, good heat transfer, sufficient combustion, smoke suppression and dust removal for unburned gas after secondary combustion, and is one of the smaller steam and heating equipment. small-scale Horizontal fuel oil steam generator factory The characteristics of the whole industrial boiler are obvious, with high thermal efficiency and sufficient steam. The whole industrial boiler is equipped with excellent safety valve, pressure regulator, low water level and other multiple protection devices, which can effectively ensure the safe operation of the boiler. Moreover, industrial boiler equipment is compact in structure, small in floor area, elegant in shape and bright in color. Therefore, it plays an important role in many large factories and coal mining enterprises.
The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Hunan Horizontal fuel oil steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. small-scale Horizontal fuel oil steam generator factory Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.
The starting of gas-fired boiler shall be carried out according to the operating procedures. The following is the accurate starting process of the analyzed gas-fired boiler: turn on the main power supply, start the gas-fired incinerator, and close the vent valve on the drum when it emits steam. Hunan Horizontal fuel oil steam generator Check the manhole, handhole flange and valve of the gas boiler. If any leakage is found, fasten them. If leakage occurs after fastening, shut down the boiler for maintenance. When the gas pressure of the gas boiler rises by 0.05~0.1MPA, make up water, blow down, check the experimental water supply system and blow down equipment, and flush the water level gauge together. When the gas boiler pressure rises to 0.1~0.15MPA, flush the pressure gauge trap; When the gas pressure of the gas-fired boiler rises to 0.3MPA, turn the "load high fire/low fire" knob to "high fire" to strengthen incineration. When the pressure of the boiler rises to 2/3 of the operating pressure, start pipe warming and air supply, slowly open the main steam valve to prevent water hammer. small-scale Horizontal fuel oil steam generator factory When the drain valve emits steam, close it. After all the drain valves are closed, slowly open the main gas valve to fully open, and then reverse it for half a circle. Turn the "Control of gas incinerator" knob to the automatic gear.
Enterprises that rely on coal for power generation are both traditional power enterprises and highly polluting enterprises. The industrial waste gas discharged by coal power generation enterprises has seriously polluted our living environment. Hunan Horizontal fuel oil steam generator As a result, the country has become more and more strict in the control of this industry, and how to use waste heat recycling power generation has become a topic of concern for many enterprises. Waste heat boiler can meet this demand of enterprises, so its application in coal mine power generation enterprises is more and more. small-scale Horizontal fuel oil steam generator factory Installing a waste heat recovery boiler on the exhaust pipe of the coal mine gas generator set, using the waste heat discharged by the coal mine gas generator set to generate steam for power generation, can not only turn waste into treasure to realize the secondary utilization of energy, achieve the goal of combining coal mine gas control with energy conservation and emission reduction, but also reduce environmental pollution, kill two birds with one stone.
During the operation of the gas generator set, the full combustion of gas and air generates a large amount of heat energy. The heat energy is converted into mechanical energy through the crankshaft connecting rod mechanism, and the generator converts this mechanical energy into electrical energy. However, some of the heat energy is still taken away by the exhaust gas and discharged from the cylinder block, resulting in the exhaust gas emission temperature of 500-600 ℃. In order to avoid this part of heat loss, waste heat boiler is used. If the high-temperature waste gas is directly discharged without treatment, it will inevitably cause excessive temperature in the workshop, accelerate the aging of equipment, affect the service life of equipment, and lead to a large use of cooling circulating water for the unit. If the waste heat boiler is installed, it can not only solve the above problems, but also generate steam energy for production and domestic use in the mine, so as to realize the recycling and comprehensive utilization of resources.
Most people may already know something about flue gas waste heat recovery, because they have already explained a lot about it. In order to let you know the relevant knowledge of flue gas waste heat recovery, the following is a brief introduction to the two methods commonly used for recovery. Hunan Horizontal fuel oil steam generator Two methods are usually adopted for flue gas waste heat recovery: one is to preheat the workpiece; The other is to preheat air for combustion support. The flue gas preheating workpiece needs to occupy a large volume for heat exchange, which is often limited by the operation site (this method cannot be used for furnaces that are used intermittently). small-scale Horizontal fuel oil steam generator factory Preheating air for combustion support is a good method. It is generally configured on the heating furnace, which can also strengthen combustion, speed up the temperature rise of the furnace, and improve the thermal performance of the furnace. This can not only meet the requirements of the process, but also achieve significant comprehensive energy-saving effect.
