Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.
Buy commercial gas hot water boiler what are the considerations in the purchase of commercial gas hot water boiler, heating area should be combined, using local and confined space, etc. to purchase. Due to the high quality requirements for commercial boilers, so be sure to choose the ISO9001 and ISO14001 certifications of production of the product, which can maximize the protection of boiler quality. So in the purchase of commercial gas hot water boiler which specific precautions have it? Notice how the first combustion efficiency. Because commercial gas hot water boiler needs an uninterrupted water heating, all-weather operation, they must first pay attention to the thermal efficiency of the boiler at the time of such purchase, should pay attention to the fan frequency combustion device is optimized design, try to choose the microcomputer monitoring AC variable frequency fan , so that the fan speed can be adjusted according to the combustion gas consumption, it can ensure the maximum combustion efficiency. Note how the quality of a second circulating pump means in the entire gas hot water boiler, a circulating pump is one of the most easily damaged parts, so that the purchase of a good quality is important to note how the quality of the circulating water pump when gas hot water boiler quality, should select the type of high-temperature water pump, in addition to the noise problem concerns the pump, its low noise, vibration small, long life typically boiler. The third pay attention to whether there are security devices in the purchase of good quality gas hot water boiler, also can not ignore security issues, such as whether there is a double off the gas solenoid valves, solenoid valves to avoid failure caused by gas leakage accident. The fourth note whether there is anti-jamming function is based on the special nature of commercial gas hot water boiler, the boiler has to be concerned about whether anti-jamming features, both related to the life of the boiler, but also related to the stability of the equipment, can not be ignored. These are a few considerations to buy commercial gas hot water boiler. For the most cost-effective to buy a hot water boiler, but also concerned about the way water cycle and energy efficiency, heating temperature range of issues such as price compared to ordinary commercial hot water boiler boiler slightly higher, but the multi-function, if it can pay more attention when buying such a device would allow the service to life.
Phenomenon boiler full of water, causes and how to deal with? Phenomenon boiler full of water, causes and how to deal with? Boiler filled with water phenomena: (1) the water level is not visible or not, a high level alarm; (2) steam temperature decreases, main steam isolation valves and the turbine inlet valves visible white steam; (3) turbine or steam pipes occur water hammer; (4) water flow is not larger than the normal steam flow. Boiler full of water: (1) water supply is automatically jump manually, resulting in abnormal increase of water supply; (2) or the drum set safety valve on the steam header, or causing the water level to rise with water; (3) boiler evaporation overloading or more, it occurred priming. Boiler full of water: When the steam pressure in the boiler and pressure to normal, while the drum water level rises, exceeds + 50mm, should take the following measures: (1) were compared with two wash drum water level gauge to check its instructions is it right or not. (2) from the automatic to manual adjustment of water supply, water supply and close the door manually turned down and to reduce the total water supply amount adjusting gate. After treatment as above, within the drum water level is still rising, exceeds + 75mm, should be carried out the following measures: (1) to open the door for emergency drain drum should be put to the normal water level water level shut down immediately. (2) The steam temperature, the heated reducing or closing off the small door, door open and main steam superheater tubes hydrophobic hydrophobic gate. When the treated drum water level continues to rise, and exceeded the upper drum water level meter water level visible, on emergency shutdown, as soon as possible with the main pipe splitting, immediately stop the water, recycled to open doors, turn on the water to strengthen the boiler and steam drum note an upper level of the water table appears to be put to the normal water level off. Standby normal furnace, to obtain the consent of value, according to Stoke furnace operation. As the water level in the steam drum water level tables invisible, not in time, should take the following measures: (1) were compared with two wash drum water level table, check the instructions are correct. Full drum water level tables turn on the water door, turn on the water and then slowly close its doors, as there is water in the water table appears, and water levels continue to rise full of tables full of water and has not been proven boiler water level gauge steam over the side of the tube, press the emergency shutdown process. (2) open the door turn on the water table level, and slow to close its doors after the turn on the water, the water level in the water table invisible. To prove a serious full of water, soda and then close the door, turn on the water to open the door, the water level of the water table memory after the release to do, turn on the water shut the door immediately. Ajar quickly and valve inner water table level occurs, and filled with water, before this time has exceeded the determination level of the steam drum level side through the tube sheet, emergency shutdown should be treated as soon as possible and the manifold splitting. (3) When the water level in the boiler accident occurs, it is difficult to judge if the water level should be shutdown immediately. After the shutdown called by the water method called water, check the water level in the drum.
Horizontal industrial steam boilers cost typically less up front than watertube boilers, and offer lower operating costs when compared to a similarly sized watertube boiler. They are also easier to maintain due to better fireside access and their efficient straight tube design.
