locomotive atmospheric steam boiler for sale
This year, located in Guizhou Tongzi County and located in Heilongjiang Harbin has two boiler explosions accident, after investigation, the accident was produced in the installation link, there are companies the main responsibility for the implementation of incomplete installation link, confusion installation and construction management , unauthorized commissioning, pressure testing irregularities, installation supervision and inspection to ensure the role of the missing and other problems, leading to a boiler explosion occurs, causing adverse effects for the personal and property safety.
Market supervision bureau to draw lessons from the accident, in order to avoid explosion due to boiler installation problem from occurring again, issued a notice warning of the risk of boiler installation link. Details are as follows:
The boiler safety related technical specifications, the entire boiler manufacturing unit can be installed (set) mounted boiler units produced. Boiler manufacturing unit undertake installation work, should meet the following requirements:
The manufacturer should be dedicated departments boiler installation work, set up to cover the boiler installation quality management system, equipped with the necessary resources to installation conditions. Boiler manufacturing units should strengthen sales management, through specified in the sales contract if the terms of the unit responsible for the installation of boilers, etc., to prevent sales by the manufacturing license qualification units or organizations which are not allowed to undertake the unit personnel to carry out boiler installation work. Where specified in the contract manufacturing sales unit responsible for the installation, on-site installation work must be sent by the company to complete the installation personnel shall not be subcontracted to other units (safety specifications are allowed in the assigned project except). Indicate the sales contract to this unit responsible for the installation of the boiler, installation of the unit must have the appropriate license installed. Responsible for the installation of the units should strengthen safety education and skills training for installation personnel. Find that the installation quality and safety aspects of the occurrence of an accident or appears illegal activities, special equipment safety supervision institutions should be punished according to the law to install the unit.
Boiler installation units should strictly enforce the relevant safety standards and technical specifications to ensure the quality and safety of boiler installation, the unit should be installed at the installation site set up signs stating the name of the license holder of the certificate, license project, license number and items the person in charge, who is responsible for safety and quality, commissioning personnel, supervisory inspector's name, unit and telephone. Boiler commissioning and commissioning, operation must be performed by a licensed boiler operator. Before the boiler installation, inspection and acceptance by the relevant formally delivered, installed units should be hung in a prominent position boilers warning signs with the words "banned" and take effective protection and quarantine measures to ensure that the boiler system can not be ignited or boost . In addition to the need to debug, the cabinet can not be energized, the fuel valve is in a closed state should be like. Use blanking panels of the boiler pressure test, the test should be removed immediately after the end of the Blind.
Boiler boiler installation situation before construction units should be installed by informing the local special equipment safety supervision and management departments, and submit an application to install Supervision, Inspection and supervisory inspection agency. Where Supervision and Inspection uncommitted boiler installation project may not start.
Supervisory inspection agency should be strictly in accordance with the "Boiler Inspection Rules", according to the supervisory inspection protocol and progress of the project requirements, arrangements for the implementation of the supervisory inspector boiler installation supervisory inspection. A class of control points, the supervisory inspector must be at the scene confirmed to meet the requirements, the installation unit in order to continue with the work. Supervisory inspector shall, at the start that is to the construction site, in the whole process of site supervision to pressure test, shall not be used after the witness confirmed that and how do fill supervisory inspection program Supervision, Inspection and replacement process when the boiler pressure test.
Boiler manufacturing unit in particular is responsible for boiler installation of manufacturing units and boiler installation supervisory inspection agency, should an accident lessons learned, giving top priority to further implement the main responsibility and checks responsibility, strengthen the boiler installation management to ensure the quality of the installation work, protect the boiler safety.
In the emphasis on strength condensing boilers run at the same time do not neglect the maintenance and inspection work. Regularly conduct a comprehensive inspection to the boiler, the boiler can not only ensure the smooth work, but also to avoid the impact due to the overall performance of the boiler minor issues.
Xi'an, Baoji, Xianyang, Weinan what type of boiler is better: Recently, Xiao Bian fast boiler discovery, both for counseling or purchases of gas boiler has been a significant improvement in Shaanxi Province, through the depth of excavation , small doubts have been answered. The advent of winter, mostly in Shaanxi around mid-November for heating, reached a peak of use of the boiler. According to China's introduction of the latest air pollutant emission standards, Shaanxi Province has been a significant amount of emission limits for new boilers and boiler construction in nitrogen oxide (referred to as NOx). According to the FIG see, Xi'an, Baoji, Xianyang, Weinan, Tongchuan etc. implement air pollution emissions of less than 30 mg / m (inclusive) for new boilers, boilers for the implementation of less than 80 mg / m ( containing) air pollution emissions.
In the past, a considerable period of time, due to various heating design emphasis on safety considerations, the design heat load calculation results are generally much larger than the actual value required, so multi-radiator, hot water boilers, large pumps, large diameter, first heaven and earth form a "big horse car" situation, low-load, high-volume operation is widespread. This is due to the mismanagement of the designer heating operation, fireman low level of technology factors affecting heating do not know enough to worry about heating is not, will not dare to cut down the heat load, resulting in equipment is still too large, creating a vicious cycle. Over the years, through a lot of practice and testing, in terms of common understanding has been great progress in the actual design and the increasingly close. (C) the low level of management is the main cause of high energy consumption.
