Jinzhou construction and installation company needs an electric heating hot water boiler house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.
Oil-fired boiler and gas boiler as the difference between the early stages of construction to complete our economy, our people's spiritual and cultural efforts to increase investment, with the attendant is demanding on the environment, air pollution is coal-fired boilers of large, first in the state it's now a rigorous, but the attendant is it a substitute for oil-fired boiler and gas boiler, that they have any difference? They belong to energy saving equipment, the combustion products of carbon dioxide and water, will not pollute the environment. The biggest difference is that they use different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil which is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, it is common for companies do not have a gas boiler operating conditions or institutions to use. Oil-fired boiler and gas boiler difference between: 1, different fuel: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point fuel boilers and gas boiler: 1, the same boiler: the same tonnage same 10 bar fired steam boilers or hot water boiler of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards. These are the difference between the oil-fired boiler and gas boiler, want to help you choose.
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, 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, 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.
Gas furnace gas steam mass identification of the method for determining the gas quality of a gas steam oven, it must have a manufacturing license manufacturer, the manufacturer must have a manufacturing license, the users must purchase gas 10 bar fired steam boilers with production of qualified manufacturers product. See calculation but also the strength and structural design aspects of the gas furnace gas and steam, the furnace is all vapor pressure, and steam oven gas liquid gas into the furnace pressure injection and suction two unpressurized species. Heat Transfer Fluid pressure element whether or not the furnace, it should be calculated according to the current standard boiler intensity calculated geotextile design pressure applied to the working pressure 0.3MPa, and not less than 0.59MPa. Secondly, it is necessary for the steam furnace gas pressure test gas, which when assembled in the manufacturing unit and the unit is mounted in use, a pressure test were performed after repair. Electrically heated gas steam boiler, its pressure test into pressure test, hydraulic pressure test and tightness test. Whether gas furnace electric heating gas or liquid steam boiler furnace, the manufacturing units have to conduct hydrostatic testing, hydraulic test only in the use of the unit, and should not pressure test. For electrically heated gas steam boiler furnace gas, but also in the manufacture of air tightness test unit and used to check the seal of the non-welded joints. Test Method airtight electrically heated gas steam boiler and the requirements of the relevant provisions of the pressure vessel is. For electric heating liquid gas steam boiler furnace, not required tightness test. At the same time, more stringent control of electric welding quality heating gas steam boiler, organic heat carrier due to the electric heating gas steam boiler easy to leakage, flammable, so the electric welding organic heat carrier furnace gas heating boiler steam requirements compared to a medium boiler water is high, the quality of welding should be strictly controlled electrically heated gas steam boiler.Free Chat
