automatic gas fired hot water boiler
Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the boiler is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube steam boiler (SZS25-2.0-YQ).
How to judge whether the burning oil and gas boiler is extinguished or not?
The indication value of the negative pressure gauge of the fuel gas boiler furnace suddenly increases; the inside of the furnace becomes black, the flame is not seen by the fire hole; the burning sound of the furnace disappears; the fire monitor emits a fire extinguishing signal; the temperature and air pressure drop sharply, and the water level drops first and then rises. These are all flameouts. If the auxiliary fan accident causes a flameout, if the power supply of the induced draft fan or blower is interrupted, there will be an accident signal; if the fuel supply is interrupted, the boiler fuel or gas pressure will drop to zero.
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 automatic 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.
Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.
