Henan gas 11 tons atmospheric boiler after shutdown within 6h Why should how to do either normal cooling or emergency cooling during the first 6h gas boiler shutdown of Henan, are required to turn off all the smoke, wind and bezel door? Normal and emergency cooling Henan cooling gas boiler shutdown, in the first 6h after shutdown are identical, are required to turn off all the smoke, and air shutter door. When the difference is that the normal cooling, can be opened after shutdown 6h cited blower baffle natural ventilation, while emergency cooling, allowing 6h after shutdown and start the induced draft fan ventilation Sheung strengthening, accelerated cooling to turn on the water . The main factors restricting Henan shutdown cooling rate of gas-fired boiler, steam drum after the shutdown should not produce excessive thermal stress. Steam and water drum furnace heating and ignition boosting contrast, because external drum Henan Shutdown of the gas heat-retaining layer, the drum wall temperature drop is slower than the saturation temperature decrease rate of the steam oven and water, is an upper boiler water vapor and the lower wall of the cooling drum. Henan by gas boiler drum water wall heat transfer coefficient is large, the lower half of the drum wall temperature decreased rapidly, while the saturated steam into superheated steam at the heating drum half. Superheated steam only a very small thermal conductivity, but also because he and the steam temperature is higher than the temperature, density, and natural convection can not be saturated steam is smaller than the saturated vapor. Therefore, the heat transfer coefficient on the wall of the steam drum is small, the temperature of the upper half of the drum decreases slowly. On the drum, the lower half of bananas due to temperature difference occurs upwardly formed deformation thermal stress. When a large thermal stress is formed in the initial drum boiler shutdown Henan gas, high pressure steam drum further, the superposition of both the generated stress is large conversion. Therefore, the initial Henan gas boiler shutdown excessive thermal stress would endanger the safety of the drum. Since the size of the drum of a thermal stress, and the furnace depends on the velocity of the steam saturation temperature of water is lowered. Therefore, the most effective method of reducing thermal stress is slow drum speed drum pressure drop. Within the first 6h after shutdown, close all smoke. Wind baffle and door are the best and most simple way to prevent excessive pressure drop drum. After the gas boiler shutdown Henan 6h, due to the chimney and the furnace wall heat capacity remains the wind, cold air from the smoke, wind door, shutter and the tube through the wall, which do not leak into the furnace at a close absorb heat to become hot air It is discharged from the chimney. So, even close all the smoke, wind baffle door, drum pressure is still slowly decline. After the shutdown 6h, drum pressure has dropped to very low levels, even though the ventilation and induced draft fan started to strengthen Sheung Shui, turn on the water to accelerate cooling, thermal stress is also small drum, and the drum pressure is very low at this time due to its two translation superimposed stress were also smaller, has not pose a threat to the security of the drum.
Innovation is the fruits of their labors in a timely manner to protect them, the group also set up a patent Group, to build the company's model workers Innovation Studio. By the end of 2017, the company applied for by the State Intellectual Property in standardization work, the establishment of a patent technology management platform. Industrial enterprises wang-wang, the city industrial prosperous and strong. Fast 11 tons atmospheric boiler threw himself into the path of innovation and intellectual development in the areas of clean fuel boilers, boiler industry forward to promote the development and enhance the overall strength of Anyang City, make yourself a contribution. Right now, fast boiler being saved enough strength, stir live a pond, in a move by chasing new road.
Two categories of gas hot water 11 tons atmospheric boiler gas hot water boiler progress has been made in recent years a leap in the development of our country, because the material is now increasing the standard of living of the people can be seen to grow and develop gas hot water boiler is an inevitable fact . Because most professional gas hot water boiler not only has a rapid self-heating system, the hot water temperature that can be achieved through intelligent management computer controller. At present, China fired hot water boiler is divided into the following two categories. A tubular. Gas hot water boiler tube type water boiler fitted with a computer controller, intelligent control function of the boiler by a smart chip, and realization of the digital automatic gas hot water boiler, the boiler furnace can control the temperature intelligent, automatic heating temperature reached stop; large screen fonts show water temperature, water temperature clearly visible. Hot water temperature can provide either heated water to drink hot water bath can be a dual-furnace arbitrarily set from low to high, the boiler. Boiler furnace is provided with a vent, you can make it in non-pressure state, to reduce the risk of explosion boilers. Second, the Drum. Hot Water boiler drum, mostly modified from the early steam boiler made, which is a natural circulation boiler water in the boiler. In order to ensure safety when gas hot water boiler heating fantasy, the height of the boiler must meet the minimum height prescribed by the state, so this type of boiler volume is large, the relative increase in steel consumption and cost. However, due to the large capacity of this type of boiler water and can maintain the natural cycle, when the system suddenly stopped circulating pump, can effectively prevent the gas hot water boiler hot water vaporization. It is also for this reason, natural gas hot water boiler circulating in our rapid development. To sum up, whether it is gas-fired condensing boiler tube or gas-fired condensing boiler drum is currently China's development is more in the forefront of the hot water boiler, both strengths and weaknesses, together make for the development of China's diversification of gas hot water boiler their own special contribution. Booming gas hot water boiler in favor of continuing the upgrading of boiler technology in China.
Power boiler pressure boiler used is a microcomputer controller, LCD screen display having a built-in backlight in its operating state and let the boiler clearly visible. Throughout the operation just need to gently press the button will be able to easily complete, and display and control functions inside the built-in controller is complete. This type of boiler pressure hydropower separate electrical heating mode, is also safe and easy maintenance, easy to clean and replace them, is very convenient.
