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 2ton-15ton coal fired 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.
Features boilers are widely used in petroleum, chemical, pharmaceutical, textile, light industry, building materials and so on. A low pressure, high temperature, safe, energy efficient features. Operating with complete control and monitoring of safety devices, the operating temperature can be precisely controlled. Reasonable structure, fully furnished, short installation period, easy operation and maintenance, ease of boiler arrangement. Since electric heating furnace Heat Transfer Fluid advanced explosion-proof structure, it can be used in factory area Ⅱ proof, explosion-proof grade C up to level. In recent years, due to the need for environmental protection and rising oil prices, many local governments and enterprises will be coal-water slurry fuel as a clean alternative to oil to be used. Especially in the small and medium industrial boilers. CWS boiler market development trend, there are two, one is modified in accordance with the way oil furnace coal boiler, namely the design (CWS oil boiler) on the basis of oil furnace system; one is in accordance with the bulk coal transformation of the way CWS boiler furnace, namely design (bulk coal water slurry boiler) scattered coal stove in the system. Before the existing oil-fired boilers plus pre-furnace. Advantages: high degree of automation, small volume, pleasing in appearance; disadvantages: complicated equipment, pre-furnace combustion pressure, high temperature, easy to ash fusion, pre-furnace coke, slag is very difficult, not suitable for continuous operation. The principle is the bulk coal boiler design, little change furnace, auxiliary substantially constant configuration parameters, the first half of the boiler combustion good, but the rear of the flue gas emission unreasonable, because different from the coal for coal-water slurry, coal slurry containing 34% to 38% moisture, so the contained amount of water vapor in the flue gas, so that dust desulfurizer two tails, induced draft fan and stack gray water condensation, clogging and corrosion. Excessive speed plus smoke, fine dust, very large friction, serious damage to the auxiliary equipment, continuous operation can not lead to a discharge portion, the discharge of non-compliance.
Pressure boiler furnace designed with the characteristics of the fuel pressure boiler furnace designed with the two main parts of the boiler body is characteristic of the furnace and the fuel pressure drum. Furnace, also called a combustion chamber, a fuel combustion space. The solid fuel on the grate furnace called stratified combustion furnace, also called fire bed furnace, and a liquid, gaseous or solid powdered fuel is injected into the combustion chamber in a combustion furnace, combustion chamber furnace referred to, also known as for the furnace fire chamber, a liquid, a gas or a pulverized solid fuel injected into the combustion chamber of the furnace, also known as combustion furnace; coal particles and air lift to a boiling state combustion furnace for combustion of low-grade fuel is called boiling furnace, also known as fluidized bed furnace; high-speed rotation of the coal particles by a gas flow and strongly cylindrical combustion furnace known as a cyclone furnace. Atmospheric overall configuration of a boiler furnace body includes two parts and auxiliary equipment. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler combustion of the original fuel should as much as possible. Different characteristics of fuel economy will reduce boiler operation and reliability. It is a natural circulation boiler drum and multiple forced circulation boiler, economizer receiving water circulation circuit connected to the saturated steam supplied to the superheater of the cylindrical container. Boiler drum is made of high quality steel plate, it is one of the heaviest components of the boiler.
