In the denitration process of the boiler, the boiler heating liquid water, the water temperature rises, when it reaches the boiling point, although the heat is being added, the temperature of the water will not be increased, remained at the boiling point, add heat to the water only into steam, i.e. from liquid into gas. This does not change the temperature of the substance to cause a change of state of heat (also known as a phase change) is referred to as latent heat. 1Kg liquid becomes completely saturated with the heat absorbed by steam at a temperature, known as the latent heat of vaporization at this temperature, represented by the symbol r, in units of kJ / kg.
Where is the cheapest product for sale? That's right, it's the cheapest unit to sell. All goods are at the factory price is the cheapest, because there will not be so many processes to charge or there will be merchants in the rebate, the same is true of gas-fired boiler scaling cleaner in delhi insms. For many people, gas-fired boilers, which are cheaper and of guaranteed quality, need to be purchased directly from manufacturers. Because it saves a lot of money, it will be cheaper when you buy it, but manufacturers are often in their own cities, so if you want to buy the cheapest gas boiler, the best way to buy it is to buy it online. .
All along, Zhangjiakou City, Hebei Province, took the central environmental protection supervision "look back" as the main problem of feedback opportunities to enhance the ecological environmental protection, pollution prevention and fight tough fight, active rectification, hard to rectify, resolute reform, promote the environmental reform task completed on schedule. We understand that in 2018, Zhangjiakou City Daly to promote projects cut coal, the accelerated clean alternative to coal consumption year on year in 2017 to reduce 1.04 million tons.
For unfinished "2017, the province's energy cut carbon coal down the main points of" cut annual coal requirements of mission objectives problem, Zhangjiakou City, supervisors coal companies cut coal, high quality coal, strengthen energy-saving technological transformation, to fully grasp the total coal consumption control and reduction of bulk coal.
The strengthening of key coal enterprises cut coal, to promote energy-saving technological transformation projects, several key coal enterprises to continuously improve energy standards. And vigorously promote the project minus coal, coal production in 2018 to defuse 8.6 million tons, out of coal-fired boilers 1663 units. Accelerate clean coal alternative, clean winter heating selected pilot cities in northern, rural complete "electricity instead of coal", "substitution of gas for coal" 6971. And vigorously develop renewable energy sources, as of 2018 the city's renewable energy installed capacity of 13,454,800 kilowatts, accounting for 74.2% of all electricity installed capacity, the highest in the country.
By the flue gas is added to the combustion products within the combustion zone, not only lowers the combustion temperature, NOx formation is reduced; simultaneously added to the flue gas reduces the oxygen partial pressure, which will reduce oxygen and nitrogen generating process of thermal NOx, whereby reduce the formation of NOx. Depending on the application of the principles, applied in two ways flue gas recirculation, and internal recirculation of flue gas are recirculated to the external smoke. For external flue gas recirculation techniques, the flue gas from the outlet of the boiler scaling cleaner in delhi insm via an external conduit, re-added to the furnace. According to the study, external flue gas recirculation can be reduced to 70% of NOx formation. The ratio of the outer loop NOx control effect has a greater impact, as the outer loop increases the proportion of NOx reduction rates are more obvious, but the electrical energy consumption for circulating air will also increase.
