Hot Selling Gas Coal Steam Boiler
Natural gas boiler once a day to check how long it takes much time to check the gas boiler natural gas boiler includes a gas water boiler, gas hot water boiler, gas hot selling coal steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath , gas boilers name suggests refers to the fuel gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. According to market surveys, gas boilers and coal-fired boilers scheduled inspection time, like once a year, April 19, 2018, the special prosecutor in Daxing District in Beijing Yizhuang three sheep, six 68MW heating Limited (approximately equal to 40T) of gas heating boiler regular inspections. On-site inspectors checked the calendar year of inspection reports, operating records, factory data boiler, the operator asked in detail about the boiler operating conditions during the winter heating, internal inspection carried out in accordance with these four boiler inspection program. Focus on examination of water tube boilers, membrane wall inside the furnace tubes, burners, fire insulation materials, while making inspection records.
Small series to introduce horizontal hot selling coal steam boiler steam boiler arch horizontal tube plate with threaded pipe drum composition, high heat transfer efficiency, boost fast enough output, high overload capability, hard fouling smoke tube. Today, let us together look at it. Horizontal welding binding sites steam boiler using high-temperature region and large machining bundle special treatment to ensure the welding quality and service life. Flammable, widely used fuel, burn bituminous coal, anthracite coal, firewood, industrial waste, organic waste and so on. It solves the problem of tube plate crack, eliminating the dead zone at the bottom of the drum, good water cycle effect, prevent the lower drum drum kits. Horizontal steam boiler compact structure, small dimensions and saves capital investment, easy installation, tipping valves, and piping to run hydropower. Stable, easy adjustment, the unique design of air sealing, bank up a fire a long time. Times atmospheric pollutants are oxides of dust, sulfur and nitrogen contained in horizontal steam boiler flue gas, which can achieve emissions targets Protection index when a predetermined number of times to unpurified. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area.
Are gas-fired hot selling coal steam boilers environmentally friendly? Gas-fired steam boiler, which can be regarded as a gas-fired boiler, can also be regarded as a steam boiler. This boiler, from a professional point of view, is an environmentally friendly boiler, compared to oil and coal-fired boilers, because it uses gas. Moreover, the thermal efficiency of this kind of boiler is very high, can reach more than 90%.
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.
