centrifugal water pump for high pressure boiler feed
2019, Nanjing for more stringent ozone pollution, for volatile organic compounds, governance and control measures nitrogen oxides unabated.
Nanjing Ecological Environment Agency staff members at atmospheric introduction, with the recent temperature increases, there has been a trend in some parts of ozone exceeded. This summer, the environmental protection department will introduce stricter air pollution control measures, starting from the two aspects of governance volatile organic compounds and nitrogen oxides to reduce ozone pollution.
It is understood that Nanjing will be completed this year 44 companies VOCs governance and thermal power, cement, bricks and other building materials industries fugitive emissions-depth treatment in the city in batches with a gas-fired boiler 936 units, the implementation of the nitrogen oxides governance Sector Engineering; city station 475 to achieve ultra-low emission particulate biomass boilers, for the privately polluting fuels blended biomass boilers embodiment eliminated. It is worth mentioning that the revised "Nanjing Atmospheric Pollution Prevention Act," to be implemented next month. Among them, organic solvents, paints use, as well as volatile organic compounds corporate governance and management have put forward new demands.
2. Membrane water wall structure can ensure the seal ability of the furnace and improve the centrifugal water pump for high pressure boiler feed efficiency as well.
3. Water cool structure can not only improve the rigidity and the reliability of the arch but also extend the service life.
Gas hot water centrifugal water pump for high pressure boiler feed in the use of the process What are the requirements for water and water temperature? Gas hot water boiler in the use of the process has on water and water temperature What are the requirements? In general, gas hot water boiler water temperature is no uniform requirement, the need for specific requirements based on furnace and boiler equipment such as its model, the basic points for the high and low temperatures two kinds. In addition, for each boiler water temperature control, are provided with an alarm device, once the phenomenon of over-temperature, alarms will alert to remind fireman timely adjustments. Of course, for boiler water quality this one, if the water is not up to it, then the impurities in the water will cause the boiler appears scaling, corrosion and other phenomena during the latter part of the operation, thus affecting the safe operation of boilers and other operating life and quality of supply etc., must be strict control of boiler water quality, treatment compliance. In short, both the gas hot water boiler water quality or temperature of the control must do rigorous, at their job, do their business, should not sloppy, resulting in unnecessary human and material losses.
The importance of energy saving steam centrifugal water pump for high pressure boiler feed steam boiler also the vast majority of current China to gas-based, not only high energy consumption and serious pollution. Chinese steam boiler and the current thermal power of approximately 72% to 80%, usually lower than the international level, and a uniform practical operating power only 60% to 65%, and even small steam boiler lower, and 15% to the level of the international 20% . There are generally high energy consumption under the main question of the formation of Chinese steam boiler the following: First, the selection of unreasonable steam boilers, low power form the actual operation of steam boilers are often operated under low load conditions in the practical application. The primary reason is because the use of the unit in the procurement of boilers, usually by using the maximum amount of steam boiler steam to the election, so it is simple to form a "big horse car" phenomenon, the formation of hot steam boiler power down. Because the design of a steam boiler, the maximum operating power is generally a multi-boiler heating power in the highest load of 75% to 100% of the operation. The low boiler load and overload power boiler operation will form drops. Second, the skills of burning steam boiler China steam boiler burning skills are not very current leader, boiler air ratio over too large. Excessive air ratio and added amount of flue gas, the flue gas away excessive heat, exhaust heat loss to increase, together will form the pollution increases, the flame temperature drops, the boiler heating power becomes low. Third, the boiler water quality can not guarantee that most of the steam boiler is equipped with a water softener equipment, soft water treatment equipment but the uneven quality of equipment, soft water equipment selection, some too small, so the formation of steam boiler water treatment to meet the national standards . Water quality standards will form boiler scale, affect the number of boiler steam boiler thermal power life will decline. Fourth, the level of automation of steam boiler China's current low level of automation steam boiler is relatively low, there is no appearance of some equipment operation monitoring. Because deficient show and manipulate the appearance of the boiler, some operating parameters can not be adjusted in time, the boiler can not operate in the best condition. Frequency and temperature compensation deficient active manipulation skills modern boilers, makes the best steam boiler steam load can not be reached. Steam boiler energy conservation is a long job, first and foremost still wants to build a factory steam boiler steam boiler to manipulate energy conservation through energy innovation skills.
