The basic characteristics of Henan Henan gas commercial electric hot water boiler in asia gas boiler used before use, you must first understand some basic features on the boiler used. Henan gas boiler can well adapt to low oxygen combustion, while its air coefficient is smaller than coal and oil. Burner means disposed substantially as long as a suitable and properly adjusted combustion, as long as the excess air factor slightly larger than 1 which can ensure complete combustion. Flammable and rapid combustion, the flame length is short compared to the crude oil boiler. It explains the heat transfer effect from the combustion gas heat transfer point of view, because of its solid content of fly ash and flue gas carbon black particles is very low, thus forming a weak radiative heat transfer. While high water vapor content in flue gas, triatomic gas formed strong radiation. The degree of contamination and fouling Henan gas boiler heating surface to reduce the heat transfer effect is enhanced. And because the calorific value gaseous fuel quite different from 12000kJ / m3 to 12500kJ / m3, and therefore the size of the furnace or furnace can not be compared with oil-fired boiler, but also some differences between different gas fuels. Since the gaseous fuel in hydrogen content than coal, fuel oil is much higher, the higher the water vapor content of the post-combustion flue gas. Failure to take technical measures to recover the latent heat of vaporization of water vapor in the flue gas, the thermal efficiency of the boiler will substantial improvement. Due to the higher water vapor content of the flue gas, so the gas boiler low load operation is easy to produce the tail condensation of water vapor, resulting in low water pressure or flue element at the reservoir, the refractory insulation material is wetted and failure. While also easily lead to corrosion of the metal, and even affect the normal operation of the boiler. Due to easily form explosive gas gaseous fuel and air mixing in a certain ratio, the gas flame furnace fuel leakage or human combustion chamber has caused a risk of explosion, so the use of high safety requirements in Henan gas boiler. For example, next to the boiler, gas pipeline leak detection have a special need; 1. ensure safe ventilation of the boiler; 2. Electric Explosion done in place; 3, especially the preparatory work before the start of the boiler must be in strict accordance with the procedures and controls safety requirements saver purge the residual gas in the furnace. Since the gaseous fuel ash, sulfur and nitrogen content relative to the coal, oil must be low, the content of suspended solids in the combustion products is very low, and carbon dioxide. Hypoxia taken combustion, oxides of nitrogen formed by combustion (NOx) small amount, and for inhibition (NOx) generation amount of nitrogen oxides a high temperature is also easier to implement than other fuels. Therefore, Henan gas boiler to meet more stringent environmental requirements.
Further promote air pollution control work, the Office of the ecological environment of Shanxi publicly stated: Shanxi Province will strictly control the total coal consumption; reduce the proportion of coal in primary energy consumption; Where ban on coal sales area of coal and coal products, both will be subject to heavy penalties.
Shanxi Province has also developed regulations, Municipal People's Government in accordance with the requirements to improve the quality of atmospheric environment, urban built-up area designated as the ban on coal zone, and gradually extended; counties (cities, districts) People's Government may delineate the scope of ban on coal zone according to the actual situation but life should be a primary consideration the needs of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.
At the same time, governments at all levels in Shanxi province will also strengthen civil bulk coal management, prohibit the sale, does not meet the civil standard of quality coal for coal; prohibition of lignite, coal washing, slime and other low-quality, low-grade coal as a civilian coal use. Various localities will accelerate the cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion of distributed coal-fired heating boilers; central heating pipe network coverage prior to the completion of use of scattered coal-fired heating boilers have been built and can not meet emissions standards coal-fired heating boilers, demolition will be completed within the deadline.
For violation of the provisions, sales do not meet the quality standards of civilian coal for coal, or the ban on coal sales coal region and its products, the people's government above the county level by the market supervision and management department confiscated of raw materials, products and illegal income, impose a fine of three times the value of the amount more than doubled.
More details gas commercial electric hot water boiler in asias should be promptly after use as a steam boiler plant drainage, heating, bath with gas boiler is a kind of fuel for the gas equipment (fuel gas-fired boilers), because it is compared with oil-fired boiler, electric boiler up more economical, which is widely used. After carrying out the gas boiler must turn on the water to be disabled. Why is that? We will come and detailed discussion about this issue today. To turn on the water when the gas boiler is disabled: gas boiler in the boiler water if the winter will put the cracking, there will be odor and summer long embroidered, so that the life of the boiler will be reduced. At the bottom of the boiler there is a turn on the water with the section of the door, then opened, gas boiler pipes in the water will flow back to the boiler, the boiler is done and the water on it. Water level controller SZB-IV (electrode type water level alarm) 1. When the normal level of + 30mm, pump control switch contacts are open, the pump stops working. 2. When the normal water level -30mm, pump control switch contacts in contact, the pump starts to work. 3. When the normal water level of + 50mm, a first group of electromagnets high gas boiler water level contacts the combined output high level alarm signal. 4. When the normal water level of the gas boiler -50mm, a second group of electromagnets in conjunction with the low water contact output low water level alarm signal.
Use electric pressure commercial electric hot water boiler in asia precautions Currently, the hottest senior electrical pressure boilers to produce thermal energy equipment is a high temperature and pressure, which is used in a broad walks of life, such as: electrical, mechanical, chemical and civil heating boiler needs supplying a large amount of thermal energy. However, users in the use of electric pressure boiler noticed a few things to be careful to ensure the normal operation of equipment. So, to give you interpret the following considerations for running electric pressure boiler? Details are as follows: first, to adjust the current device Feed Mode, since the electric pressure hot water boiler stops operating boiler system is set off, the user pressure boiler and electrical heating system should pay attention Sheung respectively. In addition, users first need to boiler water filling boiler expansion tank to the lowest level and thus the system Sheung Shui. Meanwhile, electric boiler pressure system should pay attention to the water-filled gas discharge apparatus. Second, note that the electrical ignition test apparatus boiler pressure before ignition starts, the user in addition to various auxiliary boiler inspection equipment, which automatically open and close the valve should pay particular attention to whether the water sensitive and reliable opening and observe boiler change, if the device stops operation, the water level rose rapidly, the devices automatically open and close valve leakage serious, users should be timely maintenance or replacement of components of electrical pressure boilers. Third, pay attention to the temperature change in the electrical equipment is running as the water temperature is too high pressure hot water boiler circulating pump is likely to cause vaporization of the entrance that affect the normal operation of the pump device. Thus, the user should pay attention to the use of the device to be electrically controlled pressure boiler water temperature, and the water temperature of the device should be controlled below 90 ℃. When addition, if the user needs a long time to stop the electric boiler operation pressure higher discount, the user should access the boiler outlet valves closed, so preventing the circulating water in the system was poured into the boiler device is formed empty the system high pressure boiler electrical phenomenon to affect the start again. All in all, users in the use of electrical pressure boilers should pay attention to these matters can only facilitates the subsequent use of the device.
