steam boiler gas for heating South Sudan

Luoyang, Henan Province issued the "Luoyang coal consumption reductions embodiment (2019-2020 years)", the program proposes: To continue to promote alternative coal consumption reduction, the implementation of industry "electricity instead of coal" project.

2016-2018 years, the city of Luoyang excess capacity, coal-fired boiler demolition, energy saving, clean energy alternative through a series of measures to resolve the power industry, pushing the total coal consumption control achieved some success, but the energy mix partial coal, thermal power installed capacity of migraine and thermal power multi siege pattern has not fundamentally changed, there is still emphasis on the industrial structure, high energy-consuming industries continued to increase the proportion of energy consumption, coal consumption is highly concentrated and other issues. Especially since 2018, comprehensive energy consumption of coke, chemical high energy-consuming industries rise significantly, the whole society electricity demand continues to grow, the amount of coal for power generation system tune up utility power plants rise, not fall, some counties (cities, districts) large-scale industrial coal consumption rise, not fall. Therefore, Luoyang City will continue to work to phase out coal-fired boilers to improve the quality of atmospheric environment.

"Plan" put forward the overall goal of coal governance: By 2020, the city's total coal consumption and strive to 2015, down from about 23% control in less than 20.3 million tons. Among them, the total consumption of non-coal power industry control in less than 9.6 million tons, the total coal consumption in coal-fired units ganged public control in less than 10.7 million tons.

"Plan" requirement, the industry needs all kinds of hot water, steam, hot air in the production process, and gradually promote regenerative and direct thermal electric industrial boiler applications. In the metal processing, casting, ceramics, refractories, glass and other industries to promote electric furnaces, industrial kilns and encourage qualified to carry coal to electricity.

Vigorously promote clean heating pilot city construction, 2019, 2020, respectively, the implementation of urban and rural residents electricity instead of coal, 110,000. 2019, 2020, respectively, to complete the electrical heating 500,000 square meters, 800,000 square meters.

In addition, the "plan" also proposed to accelerate the development of clean energy and new energy, the implementation of comprehensive improvement of coal-fired facilities, the city will no longer approve the domain, and the new 35 tons of steam coal-fired boilers, accelerate the elimination of 35 tons of steam / h and coal-fired boiler.

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.

3: Convenient

Gas-fired steam boilers are also more convenient to use in operation, so they will be favored by users of all enterprises. All natural gas pipelines are just as convenient as tap water for domestic use, and there are no problems with sustainable use. It eliminates the cumbersome work of using coal to transport or stack and clean coal cinder.

Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.
