essential requirements of a good steam boiler

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.

40t/h CFB Boiler Project Details:

Guangdong Ruyuan project required 40 tons CFB circulating fluidized bed boiler, The models is DHX40-1.25-AI circulating fluidized bed boiler provide by ZG Boiler. DHX40-1.25-AI circulating fluidized bed boiler, the use of the past 20 years to develop clean coal combustion technology, with high combustion efficiency and low NOx emissions, strong load adaptability, highlighting the advantages of combustible low quality fuel. In order to meet the 40 tons of circulating fluidized bed boiler customer demands, ZG started into production once got the orders.

A method of cleaning a boiler, a chemical cleaning process: descaling water rinsing → pickling → water rinsing → passivation; 2, independent of the other system is disconnected the boiler, the cleaning tank, the washing pump is coupled into the boiler with a closed cleaning 4, the end of the rinse water; loop; 3, in a simulated cleaning state washing system leak check, while the boiler remove loose dirt, at the outlet of the flushing water when no visual presence of large foreign particles, the end of the flushing water in circulation cleaning tank Add "Yunqing boiler cleaning powder", the main controlling the cleaning in 3-6% concentration, temperature in the range of 50-60 deg.] C, decontamination wash cycle within the system, cleaning time 2- about 3 hours. PH measured by pH paper Timing acid value of (1/20 minutes), it was maintained at 1 or less, when the pH value is stabilized within half an hour, and purge the system without gas evolution, the pickling process ends; 5, after passing rinse water, circulating add "Yunqing passivation pre-film" passivation to improve the corrosion resistance of boilers. After concentration of the whole system is stopped mixed solution was warmed to about 60 degrees cycle, soak for 2-3 hours, the passivating liquid discharge system, the cleaning process is ended. Note: 1, this product can not be eaten; 2, process handling, operation, wear protective clothing. Packing: plastic bags: 1 kg / bag 25 kg / bag.
