Electric electric hot water boiler systems sri lankas not only need to be strictly checked when buying, but also need to use the code of practice, so as to avoid the danger to the person. The electric boiler uses a long time will have the aging phenomenon, then how to carry on the maintenance to the electric boiler? In general, the electric boiler should be repaired and maintained within 1 year or 2 years, which is helpful to the normal operation of the electric boiler. Regular maintenance is also the basic to ensure the normal operation of the electric boiler. 1, when maintaining the boiler, the power supply must be cut off and pressure relief must be made. 2, burners should be removed every two months from the boiler body, carefully remove carbon deposits and dust and other foreign matter. Monthly wiping of photo-electric tube surface Clean the oil filter at all times, and carefully clean the oil pump's inner filter screen without damaging the gasket. Burner must not run without oil, so as not to damage the oil pump. 3, the water level gauge should be kept clean at all times, open the cleaning valve once a day to ensure clear water level. 4, the safety valve is pulled once a day in case of rust failure. After the work, check if the tools, materials, accessories are complete, to prevent remaining in the furnace and other spaces. Special person delisting, acceptance and acceptance of qualified before leaving the work site, final maintenance records, in order to prepare after the inquiry.

Henan newly installed gas electric hot water boiler systems sri lanka 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.

The basic characteristics of Henan Henan gas electric hot water boiler systems sri lanka 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.

Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast electric hot water boiler systems sri lanka R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.
