Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.

County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.

Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.

Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.

Precautions gas industrial steam boilers made in china Use: Gas-fired steam boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, are dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by safety technical specifications of the factory boiler design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision, inspection and performance certificate). 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.

Oil-fired boiler body heating surface long-term maintenance methods: dry and wet. Dry maintenance method should be adopted when furnace is stopped for more than one month, and wet maintenance method can be used below one month after furnace shutdown.

1 dry maintenance: After the oil-fired boiler shut down, remove the pot water, thoroughly remove the internal dirt, rinse clean. Dry in the hearth with a light fire (be careful not to use a fire), then pack the 10 / 30 mm lump of quicklime into a tray and place it in the pan, without contact with the metal. The weight of quicklime is calculated in terms of the volume of the drum per cubic metre of 8kg, and the weight of the quicklime is calculated in terms of the volume of the drum per cubic metre of lime. Then close all manholes, hand holes, piping valves, check every three months, replace quicklime if crushed into powder, and remove quicklime and tray when oil-fired boiler re-operates.

2. Wet maintenance: After the oil-fired boiler is shut down, the boiler water should be cooled below 70 ℃, and the internal dirt will be thoroughly removed and washed clean. All the manholes, hand holes, pipeline valves and so on will be closed tightly, and completely isolated from the oil-fired boiler in operation with blind plates.

Fuel gas-fired boiler fuel gas burner operating method Burner method of operation! Consistent body oil-fired boiler and gas boiler, supporting auxiliary equipment is probably the same, the choice of different burners. Selection based on oil-fired boiler and burner gas-fired boiler: the heat value of the fuel, the fuel composition ratio of each component. (A) Fuel Burner: ① the power switch on the main power; ② start switch is pressed, the burner motor starts i.e., spark ignition electrode, after the pre-blowing time of about 7 seconds, i.e., the solenoid valve to automatically open the nozzle mist discharge, a flame after ignition spark. At this time, the photoelectrode and then stopped 15 seconds delay ignition, the burner into the normal working; ③ If the ignition is not successful, the flame is not formed, or photovoltaic systems fail to sense flame brightness, after a safety time of about 25 seconds, the alarm system operation, the cutting burner startup procedures, failure red light. ④ The red light failure, the subject 3min before pressing resume button to restart the burner; ⑤ damper position should match the size of the nozzle, has generally been adjusted at the factory, but with different pressure generated in the furnace difference is adjusted until the burner flames, the mixture was adjusted to align the air flow duct, the air volume is too small will produce smoke, excessive wind will blow out the flame, the flame stabilizer generally is not appropriate for the black smoke. (Ii) Gas Burner: main switch is turned on and the temperature control switch, power transmission to the control box, a valve is opened through short "self-test" after the waiting time, the controller starts up the burner, the combustion gas from the head discharge gas is ignited, a flame, a flame to a flame probe probe, the flame continues to burn and ignition stage to complete the operation. If the ignition failure or malfunction middle fire, gas solenoid valve will close within one second. Red button on the controller will be shiny surface intentionally "locking" To unlock the reset button is pressed, the red light off to start again. After successful ignition of the burner, adjust damper position of the burner head and gas flow to the burner well and meet the load requirements. Fuel gas-fired boiler burner configuration wide variety of brands, users must be carefully chosen, select the appropriate type and brand. The same type of fuel gas industrial steam boilers made in china and hot water boiler burner model configuration is slightly different!
