In the boiler Stoke process, why should record the amount of expansion of the expansion indicators? Pressure increased at the boiler temperature member to be expanded, the expansion in order not hindered. Excessive thermal stress in the pressure member, pressure member always take a variety of measures to compensate for thermal expansion. For example, conventional steam pipe "Π" type and "Ω" compensator is an example. There way compensation is often used with one end fixed, the other end of the heat can expand freely, the drum and the waterwall tubes often used in this manner.

15 tph WNS condensing gas-fired boiler for food industryHenan Youmai Food Co., Ltd. is part of the White Elephant Food Group and was established in 2013. It mainly develops, produces and sells "White Elephant" and "Youmai" brand noodles. Noodle drying process generally has rapid drying at high temperature, slow drying at low temperature, and medium-speed drying at medium temperature.Noodle drying is also the most invested and technically most productive process in the entire production line, and has a very important relationship with product quality and production cost. The occurrence of crispy noodles, tidal noodles, acid noodles and other phenomena in production are all caused by irrational drying equipment and technology. Therefore, White Elephant Food attached great importance to the purchase of boiler equipment for Xinzheng Factory. In 2017, White Elephant ordered 15 tph WNS condensing gas-fired boiler at ZOZEN. The front and rear smoke boxes of the boiler are filled with multi-layered aluminum silicate fibers and then insulated with high-temperature fire-resistant mud to increase the thermal resistance, effectively reduce the heat loss and improve the thermal efficiency.

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.

Defined condensing gas boiler water level and operational impact of false condensing gas boiler is a professional, highly technical work. Depending on the quality of personnel engaged in this work, will inevitably produce this or that knowledge, here, in conjunction with a variety of resources on the network! Analysis about the misunderstanding, improve operational level of technology to achieve safe and economic operation of the gas condensing boiler units. Drum level reflects the dynamic balance between the amount of water to evaporation. In the stable condition, when the amount of water equal to the amount of evaporation, the water level constant. When the amount of water to be greater than the amount of evaporation (including continuous blowdown, soda loss), the water level rises. On the other hand, the water level dropped. Unreal water level does not meet the above rule occur, known as the false water level. Condensing gas boiler water level easily lead to false, erroneous judgment of the operator, causing an erroneous operation instruction, causing serious consequences, deal with false water level, experience and strict implementation of rules depends on the operator. Master load surge, false water level plummeted formed, to adjust the water level, the smooth operation of great help. When the water level of which appear to run false condensing gas boiler, do not adjust immediately, but to wait until the water level gradually between water evaporation and to readjust the same time balance changes. Specifically, when the load surge, pressure drops, the sudden increase in water level, not to reduce the amount of water, but to wait until the water level began to fall, to increase the amount of water. The load is smaller, the pressure rises, when a sudden drop in the water level, do not increase to the water, but to wait until the water level began to rise, and then to reduce the amount of water.
