Routine maintenance routine maintenance process gas boiler gas boiler gas boiler can be divided into two parts: preparation and running before the start of the examination. Before starting to prepare: 1. Check the air pressure is normal, the valve leaks, the switching valve is in place. 2. The gas alarm system is tested to determine if it can work, and if the fan can be started. three. Check the water softening system. Softener should be in working condition, the tank level should be normal. 4. Check valve switch boiler and decontamination work. The circulation pump outlet valve closed, to start the circulation pump, slowly open the water outlet valve, the outlet pressure is adjusted to 0.3 ~ 0.35mpa, and the pressure is adjusted to reflux for 0.2 ~ 0.25mpa. Running check: 1. Open the power boiler, the boiler normal ignition operation monitoring, checking and each member state of the flame sound. 2. The heating boiler operating conditions can not be ignored, large and small units commutation control conditions should be normal. 4, the temperature difference of each recording circuit water, the water supply valve to adjust the return water temperature by two hours the water pressure and temperature recording every each circuit. 5. After checking the boiler pressure, temperature anomalies, should be stopped and checked. 6. Check the gas flow and gas pressure stability is within the normal range, to determine whether there is clogging the filter. 7. Check the pressure pump to see if there is abnormal noise and other anomalies.

January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.

Prior to 2017, the total removal of Harbin urban built-up area of ​​small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.

According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.

Boiler inspection and external examination order and the Boilermakers difference fireman: boiler products and keywords the site, because it is important and flagship product, the site box boiler, so the learning attitude, and careful attention should be paid treat, not sloppy. And here, we will, be carried out by a number of specific issues of their study and work, and give their corresponding answers, so that we can based on the original, to further deepening and expansion. 1. boiler, which is the first inspection within or outside the check? From a professional point of view, in the boiler should be seized, and then is external examination. Also, if you find a problem in the internal examination, then, is to wait until after the external inspection, if there are problems be dealt with. In addition, in the test cycle, in general, is conducted annually external inspection, internal inspection once every two years. If the same year, both internal and external inspection should be carried out, then, is outside the inside first. 2. Vertical shell boiler, which has its specific species? Vertical shell boiler, which is a boiler, in which specific species, there is a transverse vertical water tube boiler, water tube boiler vertical multi-lateral, vertical straight water tube boiler, water tube boiler vertical bending, and Li type fire-tube boilers and other such. However, for now, the latter three, is the straight vertical water-tube boilers, water tube boilers of vertical bending and vertical fire tube boiler, is using three more.

"2018 boiler intelligent manufacturing, process and equipment development seminar" held in ZBG

In order to seek new breakthroughs in innovation and seize the opportunities of future economic and technological development, China has formulated the "Made in China 2025" action plan focusing on intelligent manufacturing. From the national strategic level, it depicts the grand blueprint for building and manufacturing a strong country, and establishes the strategic goal of developing into a manufacturing power. At the same time, it clearly proposes to develop intelligent equipment and products and promote the intelligentization of the manufacturing process. With the improvement of national environmental protection requirements, the structure of boiler products has undergone major changes, and higher requirements have been placed on the quality of product manufacturing. In order to cooperate with the implementation of "Made in China 2025" and the practice of intelligent manufacturing and digital workshop in the boiler industry, summarize the new achievements in the manufacturing process and equipment development of the boiler industry. Under this background, sponsored by the Industrial Boiler Branch of China Electrical Equipment Industry Association, Zhengzhou The 2018 boiler intelligent manufacturing, process and equipment development seminar co-organized by Zhengzhou Boiler Co., Ltd. was held, and nearly 100 industry experts attended the meeting. The meeting was chaired by Wang Shanwu, Secretary General of the Industrial Boiler Branch of China Electrical Equipment Industry Association.
