The furnace liner is the combustion chamber of the horizontal gas-fired heat transfer oil furnace. The burner nozzle is placed in the front of the furnace liner, and the high-temperature flue gas generated by combustion extends to the rear, leaving the furnace liner and returning to the space. Generally, the number of times of returning is not more than four, and the common one is the three return heat conduction oil furnace. Chengdu Oil fired gas steam generator This type of heat transfer oil furnace can be divided into dry back type heat transfer oil furnace and full wet back type heat transfer oil furnace according to the structure of the flue gas reentry space at the rear of the furnace. The flue gas reentry space of the dry back heat conduction oil furnace is enclosed by refractory materials; The flue gas reentry space of the full wet back type heat conduction oil furnace is composed of a recuperative chamber immersed in water. In addition, there is a central regenerative heat conduction oil furnace: that is, the back wall of the furnace liner is sealed inside the boiler shell, and the flue gas is turned back to the front from the inner wall around the furnace liner after encountering. This type of heat transfer oil furnace can also be regarded as a full wet back heat transfer oil furnace. vertical Oil fired gas steam generator how much Although the dry back heat transfer oil furnace is simple in structure, the refractory material at the rear of the furnace liner is easily damaged, and the rear tube plate is often directly washed by high temperature flue gas. The temperature difference is large, so the dry back heat transfer oil furnace is obsolete. At present, few manufacturers produce it; Although the full wet back heat conduction oil furnace has a complex structure, it avoids the problem of flue gas sealing in the reentry space and is suitable for micro positive pressure combustion.
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.
The air storage tank in the air source system shall be installed behind the rear cooler, so as to prevent oil vapor and liquid water from gathering in the tank and reduce potential safety hazards as far as possible; The lower temperature of other air stored in the tank can also reduce the volume of the body. Chengdu Oil fired gas steam generator When connected with screw compressor and other air supply equipment, the air receiver can be installed behind the dryer. At this moment, the air entering the air receiver is dry and there is no condensate in the tank. The air tank is a pressure vessel, and each air tank shall be equipped with safety valve, pressure gauge and other necessary safety supervision equipment. vertical Oil fired gas steam generator how much The application and maintenance shall strictly comply with the relevant provisions of pressure vessels; The air tank shall be equipped with a manhole or hand hole for maintenance, and the lower part of the tank shall be equipped with a drain valve, which shall be regularly drained; The air storage tank is usually installed outdoors, so it should be protected from direct sunlight and there should be no high temperature heat source nearby.
Diaphragm air pressure tank is an energy storage device composed of a steel shell and a rubber diaphragm liner. The rubber diaphragm completely separates the water chamber from the air chamber. When water with external pressure is filled into the liner of the diaphragm air pressure tank, the air sealed in the diaphragm air pressure tank will be compressed. Chengdu Oil fired gas steam generator According to Boyle's gas law, the volume of gas becomes smaller after being compressed, and the pressure increases to store energy. The expansion of compressed gas can press the water in the rubber diaphragm out of the tank. Diaphragm pressure tank is widely used in central air conditioning, boiler, water heater, frequency conversion and constant pressure water supply equipment. It can buffer the pressure fluctuation of the system and eliminate water hammer to stabilize the pressure and unload the load. vertical Oil fired gas steam generator how much When the water pressure in the system changes slightly, the automatic expansion and contraction of the diaphragm air pressure capsule will have a buffer effect on the change of water pressure, which can ensure the stability of the water pressure in the system, and the water pump will not be opened frequently due to the change of pressure.
Stainless steel for pressure vessels and its welding characteristics. The so-called stainless steel refers to the addition of a certain amount of chromium in the steel to keep the steel in a passive state and free from rust. Chengdu Oil fired gas steam generator For this purpose, the chromium content must be more than 12%. In order to improve the passivity of steel, it is often necessary to add nickel, molybdenum and other elements that can passivate steel into stainless steel. Stainless steel is generally referred to as stainless steel and acid resistant steel. Stainless steel companies do not have certain acid resistance, and acid resistant steel generally has a good stainless property. vertical Oil fired gas steam generator how much According to its steel structure, stainless steel can be divided into four categories, namely, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and austenitic ferritic duplex stainless steel.
Waste heat boiler is a kind of industrial equipment. Although the equipment is simple to operate, it also needs special attention in practical application. Chengdu Oil fired gas steam generator So what should we pay attention to when it runs? Generally, when using waste heat boiler, we need to pay attention to prevent misfire. Due to the excessive output of the burner, the flame will disengage from the burner, resulting in incomplete combustion. A large amount of mixed gas in the furnace may cause explosion, and backfire should also be prevented. Due to the low output, the flame will retract into the burner, resulting in unstable flame flameout vertical Oil fired gas steam generator how much If the combustible gas continues to enter the limit, it may cause explosion. After ignition, pay attention to adjust the combustion gas flow, stabilize the burner pressure, so that the flame can burn stably. In order to reduce the smoke from the chimney and pollute the environment, smoke suppression and dust removal devices should be installed.
