Gas-fired steam 4000kg high pressure boilers in the demolition phase of the reform era gas boiler steam electric boiler gas development road coming our country, especially in the last five years, filled with emotion, ups and downs all the way hard, my heart constantly VERSION! In particular coal-fired boilers and demolition, network monitoring, 12 cities and gradually written off his account, forced removal of the boiler room, boiler chimney landing shift, kotelshchik examination and training, enterprise transformation phase out nuclear boiler inspection is indeed a great many times ...... rainy wind, coal-fired boiler in a new era withstand wind and rain test! Gas-fired steam boiler as of September 29, Shijiazhuang has been removal of scattered coal-fired boilers 261 units, 22 units remaining to complete the task the amount of 92.2%. According to statistics: Xinhua region removal station 99, an amount of 100% complete the task; Yuhua zone removal station 22, to complete 100%; high-tech zone removal station 13, the remaining units 1, 92.9% completion; west region removal station 87, the remaining 13 units , 87% complete; Chang'an removal station 29, the remaining five, 85.3% completion; east district removal station 11, the remaining three, 78.6% complete. Removal of these boilers can reduce coal 263,000 tons, reducing soot emissions by 3682 tons, 4208 tons of sulfur dioxide reduction. With environmental protection, energy saving, driven by strong national policy, China's natural gas supply in order to carry out rapid, agile development are other clean energy. Referrals to a variety of gas heating equipment market opportunity emerged. For the construction of heating and other industries use large-scale gas-fired boilers for single-family free-standing home heating wall-mounted boilers become small after sunrise industry. The use of gas-fired boiler fit the relevant state policies: 1, environmental protection: the use of natural gas compared to coal-burning emissions of harmful materials; CO 2 increase 58%, energy: some boiler accessories lot for surface mounted pipeline, together with the outer insulation of pipelines low quality or disrepair, resulting in significant heat loss. And to always Reparation protection, current exchange tube, forming a major waste steel, land, labor, and many other resources. 3, all-round development: the birth of a wall-mounted gas boiler effectively prevent the above-mentioned shortcomings. Single-family heating pipe network there is no loss of heating characterization, lavish, the boiler can be closed when no one at home, fewer people capable of closing does not require heating the room, the elderly or children can properly progress heating temperature, can easily extended or extended heating period. There are many aspects of the message indicates that the coming era of reform gas steam electric boiler, therefore, perfect for small and medium enterprises reform, not only with the times, but also to keep pace with the times, so as to large enterprises strong go under development.
You must know the 4000kg high pressure boilers energy problems (induced draft fan power consumption rate, steam consumption) draft fan causes problems 1.1 boiler flue dust and fouling, in particular air preheater fouling, resulting in increased resistance to smoke duct . 1.2 boiler flue, tail heating surface and dust leakage. 1.3 Leakage Rate large air preheater. 1.4 furnace excess air coefficient is too large. 1.5 unit load changes, run the adjustment is not timely, resulting in furnace pressure is too large. 1.6 unit load or low frequent starts and stops. 1.7 coal into the furnace worse, from the design value. 1.8 low efficiency filter. 1.9 draft fan blade badly worn, low operating efficiency. 1.10 fan outlet flue gas desulfurization big resistance. 1.11 soda boiler pipes for leaks. 2, 2.1 to 2.1.1 operational measures to solve the problem of the strict implementation of soot blowing system to prevent the heated area ash, blocking ash, flue gas system to reduce resistance. 2.1.2 holding the induced draft fan, the flue gas separator baffles and dampers in the fully open position. 2.1.3 The experiment showed combustion boiler, proper control of excess air in the furnace. 2.1.4 adjustment chamber negative pressure, air leakage reduction furnace and the flue. 2.2 routine maintenance and testing 2.2.1 induced draft fan performance test to determine the optimum operating point and efficient workspace. 2.2.2 boiler, air preheater, a flue, ESP and other system leakage inspection, process. 2.2.3 timely check processing chassis, shaft seal leakage. 2.3C / D repair, eliminating defects 2.3.1 down strict accordance with movement clearance adjusting fan. 2.3.2 induced draft fan blade defect action elimination hand vane opening adjustment. 2.3.3 Importers and induced draft fan baffle opening check. 2.3.4 duct tightness check process. 2.3.5 wave plate replacement air preheater, rinsed sector plate gap adjustment. 2.3.6 eliminate dust defects and improve collection efficiency. 2.3.7 clean flue gas desulfurization system, flue resistance is reduced. 2.3.8 eliminate soda boiler pipe leakage defects. 2.4A / B repair and transformation 2.4.1 Check and repair the fan blades, replace seriously damaged blades if necessary. 2.4.2 for energy saving fan efficiency below 75%. 2.4.3 The fan motor frequency transformation. 2.4.4 of the precipitator, if necessary, transform and improve collection efficiency.
We learned from Anshan City Bureau of the ecological environment: to improve air quality living environment for urban residents, according to government requirements, Anshan external publicity of the built-up areas and industrial parks and a list of more than 10 tons of coal-fired 4000kg high pressure boilerss, municipal environmental protection department also welcome all citizens supervision, to provide the city's built-up areas and 10 tons and above boiler clues industrial park outside the list.
Battle to lay the blue sky, the city has in recent years embarked on a built-up area and the city's industrial park and 10 tons of coal-fired boilers out of work, the city built-up areas and industrial parks and 10 tons of coal-fired boilers demolition of all the reservation coal-fired boilers to achieve discharge standards. As requested, before the end of 2020 in the city of Anshan City will be built-up areas and industrial parks all phase-out over 10-20 tons coal-fired boilers, coal-fired boiler units involved should be prepared in advance.
To further enhance the quality of atmospheric environment, promote environmental management to raise the overall level, in accordance with the requirements of the provincial government, the city of the city within built-up areas and industrial parks and more than 10 tons of coal-fired boilers information for publicity. These publicity boiler will be included in the list of key sewage units, strict supervision, to ensure the discharge standards.
Calculated gas steam 4000kg high pressure boilers plant to explain your boiler heating area: Gas-fired steam boiler plant to you to explain the calculation method of gas steam boiler heating area of the boiler, which is sure to install emissions-line monitoring devices, and, should environmental protection department of the monitoring center networking, so the job. And this kind of boiler heating area, specifically, then, is to be determined according to the location of the boiler, its usage and requirements. Generally speaking, if it is 1 ton, then, it is about 7000 square meters of heating area. 4 tons of gas steam boiler, which uses induced draft fan, then, that in the selection and configuration, generally speaking, if a different motor, then, there is a different choice, but specifically, then, is there are two First, Y5-47-6C, power is 15KW / 18.5kw, grade 2 is a motor; Second Y6-41-7.1C, power is 15kw / 18.5kw, the motor is four. 10 tons of gas steam boiler, between it and the workshop is to have a safe distance, and can not be a piece design, it must be independent. Therefore, it is generally to be more than 5 meters, so the job, however, can also be separated coal field.Free Chat
