3 macrotaxonomy 4 ton steam boiler supplier steam boiler fuel can be divided in accordance with the electric steam boiler, steam boiler fuel, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small single, double return the vertical structure, large steam boilers and more horizontal structure of three return. Vertical fuel gas steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. Horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving and economical use. Waveform threaded pipe and furnace structure, not only improves the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.
Startup boiler steam temperature does not mention how high do? A: In the unit to start the process, often encounter steam pressure has reached the requirements, and the steam temperature was too much difference, especially in front of the turbine and the blast furnace or red switch occurs. Should take the following measures: appropriate to increase the amount of coal to improve the furnace heat load; adjust the secondary air ratio, increase the amount of lower secondary air; improve wind, air pressure, increased gas velocity; hydrophobic and full of air and exhaust mother pipe in front of the main steam isolation all hydrophobic.
Industrial gas 4 ton steam boiler supplier 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 hot water boiler 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.
