Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)
The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.
A few days ago, Datong City, Shanxi Province, issued a "decisive battle 300 days, to enhance the" Datong blue "plan", combined with ongoing Shanxi Province: innovation, work for "the great debate, promote green development, and constantly improve the level of ecological civilization, achieve a good number of days 300 days throughout the year for more than two goals. details are as follows.
1, aspects of the transition. On the basis of the regulation last year, continued to carry out "dirty scattered" enterprise rectification work. According to industrial policy, industrial layout planning, as well as land, environmental protection, quality, safety, energy consumption, etc., to carry out an intensive investigation, the establishment of management accounting. In accordance with the principle of "first stop after the rule", the implementation of classification disposal, have been banned "dirty messy" business, appears to prevent the resurgence of the phenomenon.
2, corporate governance aspects. Industrial pollution discharge standards to strengthen the comprehensive management of enterprises can not achieve full compliance, should be taken to stop production remediation. Full completion of key industries pollution remediation work, on the basis of the city's nine power companies that run on ultra-low emissions stable, GD Datong Power Generation Co. Ltd. within the scope of the built-up area of the city and Datang International Yungang Thermal Power Co., Ltd. completed before the end of the colored Amidst the governance feasibility report, we lay the foundation for next year colored misty rain governance. December 30, 2019, to carry out ultra-low emissions and chemical industry, iron and steel, nonferrous metals, cement industry, especially emission limits transformation; completed 100 industrial enterprises fugitive emissions control, industrial furnace control 41 upgrades, 11 key industries and enterprises volatile organic compounds governance and four key industries and enterprises volatile organics management upgrade.
3, less coal ways. Insist on proceeding from reality, should be in accordance with the electric power, gas should the gas, should the coal coal (ultra low emission), should be hot is hot, and more heating energy policy to ensure the safety of the masses warm winter. Residents living coal simultaneous implementation of clean energy alternatives. District heating flat built-up area clean 100% coverage, coverage of other counties clean heating built-up area of more than 70%, 40% or more in rural areas, to proceed with the phase-out of coal-fired boilers. Renovation project to carry out ultra-low emission coal-fired boilers, October 1, 2019, 65 tons of steam coal and above and build the region (biomass) and energy-efficient boilers to complete the transformation of ultra-low emissions, low nitrogen gas boiler basically completed the transformation.
Lowest price performance oil hot water boiler low prices to the strongest winter, the leaves are brown, temperatures plunged to let us live lives filled with rows inconvenient, this is the time when the hot water demand is growing, and because winter sunlight is not very adequate, we made out of hot water are solar water heaters have been in short supply, hot water boiler fuel at this time because of its petite size, boil water quickly into the eyes of many people, and so much hot water boiler fuel undoubtedly the best manufacturers in the Henan party shares fast, and why? Here we have to analyze the production of fast river south of the shares of oil hot water boilers What are the advantages: 1, fully automatic computer control, without hand operation, automatic working set period of time, save energy and reduce heat loss, continuous The hot water, auto-sensing replenishment. 2, the inner tube inserted into the furnace barrier sheet tobacco smoke, heat transfer, reduced exhaust gas temperature, the thermal efficiency of over 90%. 3, digital display of temperature, temperature control, over-temperature protection, automatic control functions can ensure plainly drinking water. 4, imported burner, intelligent control, automatic purge electronic auto-ignition, spontaneous combustion, (gas) automatically adjusting the ratio of air and oil flameout protection device. 5, superconducting technology application on boiler to speed up the transfer speed to achieve the same industry-leading level. 6, supply of hot water, the water temperature reaches the set temperature is reached, the solenoid valve is automatically opened, the hot water into the tank, to prepare the bath. 7, the use of reliable water control solenoid valve, the automatic insulation after the shutdown. 8, the liner special treatment, 100% pure quality. 9, imports of color plates, nice, difficult to corrosion.
What safety matters should be noticed in the operation of industrial boilers?
Industrial boiler is a kind of equipment which must be used by many manufacturing enterprises. It can provide sufficient thermal energy for the production of enterprises so as to ensure that the production can be carried out in an orderly manner. However, because the industrial boiler is dangerous when it is used, the workers who operate it must pay attention to the following items in their daily work in order to better prevent the occurrence of safety accidents. So what safety matters should be noticed in the operation of industrial boilers?
1. Industrial boilers should check the inlet and outlet valves of their gas meters and the main valves in front of the furnace before using them, and close them when the pipes are replaced. When opening the furnace door, we should pay attention to check the situation in the furnace, especially pay attention to the phenomenon of gas leakage, if the leakage is found, it cannot be ignited, but it should be checked and repaired in time to ensure the safety before ignition.
2, pay attention to check the flue of industrial boiler, can't have water or not and keep the flue open all the time. At the same time, no combustible and explosive products such as diesel oil, firecrackers and so on should be placed around the boiler, and safe passageways of sufficient area should be set aside.
3. Start the blower before igniting the industrial boiler and open the air valve on each burner. When igniting, we must pay attention to fire and so on. We must not put the cart before the horse in order to prevent explosion. Also note that the burner should be ignited and adjusted in sequence from top to bottom and from inside to outside.
4. When using industrial boilers, if the blower stops abruptly due to power outages and other reasons, all gas and air valves on the burner should be closed immediately and the furnace doors should be opened if necessary to prevent accidents.
5, the operating room should be equipped with a gas alarm, if found gas leakage of the county should close the indoor gas valve, and then find out the leak point and timely repair, in the course of its attention must not use open fire to detect leakage.
