4 tons coal fired DZL steam boiler
Today, the principle of 4 tons coal fired dzl steam boiler and the construction of steam boiler too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler body is the lower part of the drum, the water-cooled pipe and the Pyrotechnic pipe The combustion part is composed of a chain grate and a drive device, and a combustion chamber composed of a boiler rack on the grate frame. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan not only discharges smoke, but also It is necessary for the negative pressure operation of the boiler. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment. Steam boilers are force vessels and safety devices are necessary. All steam boilers can work better only in accordance with the correct operating methods.
What are the methods to reduce pollution mill 1, check for leakage protection and maintenance of: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, repeated use of steam condensate: Textile mills require large amounts of saturated water vapor in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, the piping, valves and heat insulated flange experience pipes, valves and flanges waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery from the boiler chimney at a temperature of 360 ℃ smoking, sometimes discharged directly into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of textile machines Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.
February 21, spring day, the CPPCC Standing Committee, vice chairman of China Zhi Gong Dang, Deputy Secretary-General, Mr. Jiang Zuojun director of the Central Monitoring Committee accompanied by relevant leaders of Anyang, fast Boiler visit the company headquarters and to carry out research. Jiang Zuojun first visited the company's R & D Center Exhibition Hall, a detailed briefing accompanied by Mr. Luhai Gang's Group President. Mr. Jiang Zuojun listened carefully to the President on various aspects of History and products, production technology, market applications and so on.
Well designed and optimized the small series main parameters of 4 tons coal fired dzl steam boiler maintenance check before delivery of submersible pumps confirm Henan fast boiler us with all the main parameters of the steam boiler optimization design and delivery of well maintenance check before confirming with submersible pumps steam boiler with other boiler Like products, in order to improve the combustion efficiency of the boiler must optimize the product, this article lists the following items index to optimize the design parameters and performance indicators as steam hot water boiler for reference purposes only. (1) to ensure safe operation of the hot water boiler steam: hot water boiler steam integral part life more than 30 years, the life by wear of the heating surface reaches more than 15 years. (2) Operation Economy excellent hot water boiler steam: Steam hot water boiler efficiency of 91% -93%, 99% combustion efficiency; small soda system flow resistance, reducing the power consumption of the feed pump; reduced gas side resistance losses, reducing blower, fan, and other auxiliary equipment mill power consumption. (3) has a good regulation performance: adjusting the combustion, steam temperature adjustment, like the boiler drum water level regulator flexible and effective. (4) investment cost savings: Enhanced heat transfer, reduce the consumption of metal, especially a reduction in the consumption of advanced metallic materials; under the premise of ensuring product quality, reduce manufacturing, transportation, construction and maintenance, operating costs. (5) High Reliability Run: available more than 90%, fewer unplanned downtime; fire, deflagration, and no accident slagging operation of the steam boiler hot water; heating surface leakage and over-temperature occurs, tube rupture. (6) has a good load following properties: rapid start and stop, load change quickly. (7) running stability: stable operation of the steam boiler parameters, thermal stress is small and easy to adjust automatically with coal and load changes. (8) slight heating surface wear, less fouling, corrosion, emissions meet environmental requirements. Check well before delivery inspection confirmed ① out with submersible well pumps, valves, and pre-population with submersible pumps line valve closed; ② confirmed wells with submersible pump inlet line valve closed temporary purged with nitrogen, removal of temporary hose, cap installed; ③ confirmation discharge line valve closed torch; ④ confirm the submersible well pump has been fully emptied medium (neat) with; ⑤ discharge line to confirm a closed valve closed; ⑥ confirmed vent valve opening (Ming row); ⑦ confirm submersible well pump body temperature was lowered to room temperature; ⑧ contact operating position within the pump power corresponding to the apparatus; ⑨ card to send electrical power plant, the pump power; ⑩ confirm that the pump motor off.
