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.

Impact of vertical high quality inspectionfree steam boiler efficiency is basically a bunch of the root causes of the country are carrying out high-profile coal to natural gas national movement, using the vertical steam boiler, very large cuts infected micro particles, toxic gases such as nitrogen oxides same time smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler. Combustion air is not sufficiently analyze the problem over the ratio: generally vertical steam boiler burner ejector, causing the air-fuel ratio can not maneuver scheduling. Lot of non-vertical steam boiler with automatic blower burner, leading to undesirable air-fuel ratio has the following several roots: air-fuel ratio does not contain points over about two cases: when oxygen is in excess, the excess cold air will have unlimited the effect of heat, resulting in increased operating costs vertical steam boiler, low vertical steam boiler efficiency; when oxygen is insufficient, will have insufficient incineration conditions, to produce low vertical steam boiler efficiency.

Steam boiler should be noted that when Di operating high specification and high quality inspectionfree steam boiler efficiency matters, strong firepower, Di is a common production equipment, but also has some of its own Di dangerous if used improperly, it will cause unnecessary trouble. So master the instructions for use steam boilers, clear during the operation Di Di precautions are necessary. Note that when then the next, the editor based on years of experience, the use of steam boilers with compliance and Di operational considerations summarized below. A steam boiler Use: When the company receives a steam boiler, boiler Di for normal use, as well as business operators Di their own safety, must strictly abide by the "Production Safety Law," "Boiler and Pressure Vessel Safety Supervision Provisional Regulations" "Steam Boiler the relevant provisions of security technology supervision regulations ". This applies to a fixed pressure steam boiler water as a medium, comprising a coal-fired steam boiler, a steam boiler fuel, gas steam boiler. Use of the boiler plant Di technology should have the appropriate certificate, have both technical documentation and construction quality boiler installation supporting information. Enterprises must attach great importance to the boiler safety. Appoint a full-time staff responsible for managing the boiler equipment, improve the management of the use of boilers in accordance with code requirements. Formulate ensure the safe operation of the boiler structure according to the type of boiler, combustion and explosion-proof requirements and procedures, fire prevention, anti-virus and other security management system and the accident approach, in accordance with its strict implementation. Do not drink alcohol and posts and off-site. Boiler should be regularly repair and maintenance, the unit can not be forced to use any security risk boiler. Should be repaired before construction drawings and technical solutions. Repair of technical expertise required reference standards and relevant technical regulations boiler. After completion of repairs, should the pattern, material quality certificate, a certificate of quality inspection and repair and other technical information is stored in the technical archives plant boilers. Non-boiler room operator banned from entering the workplace. Foreign workers must be accompanied by the relevant approval of the leadership or before entering Second, the need to pay attention to Di operational considerations when using the steam boiler: 1, before the boiler must be familiar with the operation manual, simply to protect the safety of the operator and the normal use of the device Di, before starting inspection whether the power supply voltage and the normal operation of the water, close the drain valve, open the water supply valve and check whether the pump stuck, stuck if the water pump cover remove the fan, scroll to the motor shaft can be turned on flexible state inspection or replacement of parts for boilers Turn off the power to avoid live work dangerous. 2, electric control boxes, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean, according to the boiler water quality requirements, be sure to install a water softener in use, because they do not use a water softener can cause boiler fouling severe cases can cause burst pipes cut short the life of the boiler. 3, if not in accordance with the provisions of the use of water treatment equipment caused by the above situations are not covered under the warranty, please pay attention when using sewage. To discharge once a day and with a discharge pressure of 0.1MPa-0.15MPa, can prevent clogging pipes, sewage pipes should be properly connected to prevent burns, the flexibility of the safety valve should overhaul, at least once a month to quickly pull the lever to check the safety valve flexibility it off and back seats, the safety valve should be regularly every year to the local technical supervision for verification.
