how to open the doors of steam boilers

New Year period, Tongchuan City, Shaanxi Province seized by special pressure class inspectors seize the time, nonstop, through the tireless efforts have seven working days, the time limit runs successfully completed the Tongchuan city water quality testing and inspection work hundred sets of heating boilers.

In recent years, with the state-owned enterprises "three for one industry," the pace of the transfer of a separate depth step by step, in 2019, Tongchuan City Gas Co., Ltd. and Tongchuan Mining Co., Ltd. together for the original Tongchuan Coal mining companies and construction companies and their subsidiaries heating boiler units of unified management, are responsible for heating in winter work Yintai District and Wang Yi district within the city limits and nearly 30 residential units.

After receiving the application of these reported that construction of heating boilers, special prosecutor of the city leadership attaches great importance to immediately convene all pressure classes held inspectors "to ensure safety, promote harmony" will mobilize, deploy test the backbone of the boiler units get together and reported in accordance with inspection, quantity, wide distribution and other characteristics, develop a reasonable and effective inspection plan, centralized arrangements for the inspection of boiler units, inspectors have extensive under the jurisdiction of the Meiyuan district, dragon community, nearly 30 residential and hospital infrastructure companies run first-line heating boilers, boiler to run one by one test, carried out investigation and security risks, all currently in operation has successfully completed a water quality testing and inspection of boilers, boiler inspection a total of 101 units, 90 water samples boiler. In the access to information process safety management of the outstanding problems that exist in the use of boiler units, in accordance with the relevant regulations and safety requirements of technical specifications, targeted proposed guidance. During the inspection the boiler, for general questions, on-site supervision and the use of units of the rectification. Meanwhile, the inspection found two Royal River Area of ​​boiler pressure parts leak is still sick to run for the safety problems on the spot requires the use of units to stop using the site issued a "special equipment inspection and opinions notice" to use the unit under and timely reported to the Council and served on equipment safety supervision departments seat safety supervision departments to actively supervise the use of the unit for rectification, at present, the use of hidden problems rectification units have been completed, the re-examination confirmed that security risks have been eliminated, effectively guarantee the safe and stable operation of the boiler .

20 tph SZS series gas-fired how to open the doors of steam boilers coal-to-gas project for paper industry

Industrial boiler is an important piece of equipment of the production line of the paper industry. High-temperature steam provides heat source for production processes such as steaming and drying. ZOZEN SZS series gas-fired boilers with excellent quality and outstanding performance have become the heat source equipment of many enterprises of the paper industry. This series of boiler adopts a D-type arrangement and water tube structure. The large-volume combustion chamber has good airproof and ensures complete combustion. Meanwhile, good quality alumina silicate fiber and fire clay insulation material are used to control the boiler body temperature below 45℃, which effectively reduces heat loss. Energy-saving devices are equipped at the end of the boiler to increase the thermal efficiency to above 98%. In addition, the SZS series gas-fired boilers are easy to operate. Advanced PLC intelligent control systems with various protection functions such as automatic water supply, program ignition, over-temperature control and over-pressure control can reduce costs for enterprises.

3, disruption of normal boiler water circulation, forced shutdown maintenance, increase maintenance costs

After scaling in the boiler pipes, pipe flow cross-section reduction, increase the flow of water circulation booster, serious or even completely blocked, disrupted and boiler water circulation pipe burn, forced shutdown maintenance, waste of human and material resources.

Which parts of the how to open the doors of steam boilers susceptible to corrosion it? It is noteworthy that after the end of the work, after the steam boiler is turned off, got into the water system of oxygen may be from the steam boiler is not confined place, and then integrated into the boiler, if the pressure and temperature drop, then these will be condensed oxygen become vapor and moisture so that the metal surface of the boiler, resulting in the production of a water film. If, after the steam boiler is disabled, some parts are still soaked in water, then through continuous evaporation and water vapor, bucket elevator system to produce soda opportunity to make a lot of moisture, so that the boiler corrosion. So for steam boilers, the most susceptible to corrosion which parts of it? 1, parts of the boiler economizer, in operation, its entrance areas are very susceptible to corrosion, not to mention more economizer after the shutdown. 2, when the water wall runs, its oxygen ineffective, so it's drum and fall pipe is very easy to corrosion. It is corrosive at run time, particularly severe water wall drum side after shutdown. 3, where the elbow vertical steam boiler superheater, because the long-term on the water, in addition to the water is not clean, it also led to its rapid corrosion. 4, vertical reheater and superheater, are elbow portions submerged in water corrosion. After the above description, as long as the attention of the four parts of the maintenance and upkeep, then life can be extended steam boiler.
