gas Fired Hot Water Boiler From China
Industrial gas steam boiler room planning considerations: industrial gas steam boiler room Planning Considerations What? Followed by the degree of technological progress from time to time, the rapid expansion of social economy, people's requirements for industrial gas boiler room planning have become more sophisticated. Now now, in the industrial gas boiler room planning there are still many achievements in urgent need of treatment, therefore, we have to enhance the learning and use of advanced planning practices and advanced technology, from time to time suspend the development and review of industrial gas boiler room planning, the industrial gas boiler housing plan is more suitable, safe, reliable and economical. 2, selection and use of industrial gas boiler at a reasonable selection of urban planning, boiler, environmental management and other mission boiler type is dropped purification, waste power, an important part of reasonable expenses. Set the cost of the boiler is one of the essential elements of when thinking of selection. Because the characteristics of industrial gas boiler itself, the boiler room and equipment to establish a more economical, should be used in high load industrial gas furnace heat boilers in order to reduce the volume of the furnace. Due to the absence of heating surface cleaner, slagging, wear results, the smoke may use a higher speed, reduced scale of the convection heating surface, convection through the rational placement control the industrial gas boiler capacity of coal-fired boiler with a more compact structure, dimensions small, light weight, in order to decrease equipment investment; supporting auxiliary boiler optional satisfactory work. Industrial demand for gas-fired boiler is not equipped with soot blowers, dust, slag and other equipment and fuel dryer slave device, and can save and land acquisition costs placed above equipment; the use of a gas pipeline walks as boiler fuel, not only no fuel storage equipment, supply calm and without prior preparation of fuel processing equipment, greatly simplified the trivial; civil engineering boiler room investment costs and other related costs will lower; no fuel storage, can save shipping costs, place and rest force. Boiler room non-essential equipment such as leak detection equipment for the surge equipment, measurement equipment, gas. Coal, oil, gas boiler three kinds of heat load in the opposite situation, a huge volume of coal-fired boilers, additional slack style drums, Fan, Java machine, dust collector, but also with storage of coal, slag heap place, It covers an area larger. Industrial gas boilers small volume itself, and these need not be equipped with auxiliary equipment, simply set up between a host and auxiliary room, set on more messy, covering economy. Industrial gas boiler city gas source is generally taken from the intermediate pressure gas supply line, the gas pipeline laying gas sampling point to the boiler room, then according to quell's brand, type and caliber regulating device applications, scheduling outlet pressure range, by metering the put into use. Establish a set fee just gas network tariffs, pipeline fees, hot walks pipeline fee. Gas pipeline network overall cost of capital is the sum of the gas company funds charged to the user, it can be determined depending on the circumstances around the gas company. Usually adopted buried gas pipeline type, buried depth is generally about 0.8m ~ 1.0m, seamless steel pipe can be selected or PE pipes, pipe surrounding sand 15cm ~ 20cm plating, hot water pipe laying relatively simple, somewhat messy steam pipe walks . 3, industrial gas boiler room planning results in the presence of 3.1. Selection of the size of the heat load of the boiler and its expansion tend to choose the boiler capacity, the number of great links. The larger heat load, single boiler capacity should be large. The near future can be greatly increased thermal load, it is also relatively large capacity boiler can choose, it will expand the load thought. The only thought to increase the long-term thermal load, the expansion device may leave the boiler placeholder deployment end in the boiler room, or space left on the total FIG. However, in the practice of project planning, often there is a lack of expansion heat load estimates, constitute improper boiler selection, pre-operation to cause unnecessary trouble. 3.2. Gas boiler gas regulator trivial results generally used in high-pressure (less than 5kPa) and medium voltage (5 ~ 150kPa) trivial. Gas usually before entering the boiler room will arrive this requirement. Now the gas fired hot water boiler from china is equipped with a high level of automation subsided, a calm requires the gas pressure is lower, so before further demand into a calm pace pressure boiler manufacturers themselves generally equipped. Gas pressure regulating trivial demands reliable equipment, but on the size of the gas pipeline valve is open due to the gas pressure when scheduling the gas pressure is high or low, and tempering will cause off, start and stop frequently subsided's configuration, thereby affecting the boiler work. 3.3. Gas boiler quality results planning standard gauge, the quality can not be ensured when the gas, should be provided or dust, oil and water, respectively, and a total closed drain valve before the gas main pipe before the regulator device. Most of the oil production plant in the use of oil with anger, it is often said of moisture in the summer cold weather, moisture and light hydrocarbons and other substances containing moisture, condensation will constitute a line blockage, an initiative to quell the flame, impact Heating. 3.4. Chimney condensate results because of the high thermal efficiency of industrial gas boiler, a low exhaust gas temperature, typically 180 degrees, the boiler room planning criteria (GB50041-2008) rules industrial gas boiler room chimney should be reinforced concrete or steel chimneys chimney. Chimney will appear directly in the outdoor summer steel chimney condensate freezing results, constitute icing light rusty steel chimney, would constitute a temporary corrosion, freezing severe affect chimney smoke. 3.5. The amount of air to quell the outcome's when quell Industrial gas boiler is in the boiler room, the air between the boiler must be satisfied the requirements apply to quell the device, otherwise there will be no abundant natural gas to quell working carbon monoxide poisoning.
Recently, Guizhou Province to combat air pollution, protecting and improving the quality of atmospheric environment, the protection of public health, promote the construction of ecological civilization, and promote comprehensive, coordinated and sustainable economic and social development, in accordance with the provisions of "People's Republic of China Air Pollution Prevention Law" and relevant laws and regulations of atmospheric pollution prevention and control regulations to be amended.

Common fired hot water boiler from china Accident (c) hot water boilers common accidents in addition to accidents, explosions, that there is a tube rupture. So what causes hot water boiler tube rupture is what kind of solutions does the cause of the hot water boiler tube rupture:?? Quality (1) boiler water is poor, resulting in the accumulation of impurities in the boiler, severe corrosion and other problems attached boiler tubes, not a long time to clean up in time, lead to the phenomenon of burst pipes. Material selection (2) non-compliance boiler tubes and so lead to pipeline pressure less able to cause the occurrence of burst pipes phenomenon. (3) In addition, due to the boilers used for a long time, parts of aging, wear and other phenomena more serious, there will be burst pipes phenomenon. (4) When pulverized coal boiler, oil, gas hot work, operational errors can cause the collapse of the furnace walls and furnace tube bore explosion. Solution: (1) timely boiler attached to the wall of debris to clean up after the shutdown. (2) severe damage to the superheater, boiler shutdown immediately related operations hot water, and then timely maintenance. In short, boiler tube rupture is one of boiler accident hazards of large accidents, hot water boiler during operation, should be timely maintenance, to avoid unnecessary security risks.
Hot water boiler fuel classified according to different fired hot water boiler from china fuel can be divided according to different electric hot water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; pressure can be divided according to whether pressure hot water boiler and two kinds of pressure hot water boiler, we usually call "hot water boiler" refers to the atmospheric pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler. Type water tube boiler assembly controller computer, all the functions are stored on a smart chip realize intelligent boiler, digital, automatic, user-friendly, intelligent control of boiler water, water reaches the automatic stop heating; screen large font temperature, boiler water temperature at a glance. 2, boiler water temperature can be freely set from 10 deg.] C to 100 deg.] C, the boiler can supply both hot water bath can provide water for drinking, may be a dual oven. 3, the top of the furnace through the air opening is provided, the boiler is in an unpressurised state, there is no danger of explosion, while the machine is equipped with thermal protection (ultra-high-temperature furnace during the heating tube buzzer alarm and automatically stop working, secondary overheat protection (boiler housing temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the furnace is less than the water level is very low, the boiler is stopped and an alarm buzzer) and a number of security. drum such drum type hot water boiler hot water boiler, early mostly modified from a steam boiler made, which in the case of boiler water within a boiler of natural circulation. in order to ensure safe and reliable boiler water cycle, the boiler requires to have a certain height, so these larger boilers, steel consumption, and the cost is relatively increased. However, since this type of boiler capacity and can maintain the natural water cycle, when the system pump is suddenly stopped, the pot can be effectively prevented vaporization of water. it is also for this reason, natural circulating hot water boiler in our rapid development.
