Burner gas boilers were burned there a way to solve the gas boiler has been running well, but this can not be used suddenly, after checking to confirm that the burner is damaged up. What are the reasons can cause burner gas boiler is burned? For such problems, what can be the solution? Gas boiler burners burn have a relationship with a number of factors, for example, there may be a way to let the boiler temperature deviation high, has reached the upper limit of the allowable range, so that the high temperature flue gas furnace radiation heat of the burner is enhanced, the wall temperature of the burner nozzle is increased burning. It is also possible with a gas flame furnace boiler deflected about the base, because after testing found furnace temperature and burner nozzle with uneven distribution of temperature, wind speed and orifice layer with the four corners of boiler burners significantly uneven. In addition, gas burner boiler equipment standards at fault, not the end of a stable tangential firing, but also so that the other main reason for the flame base skewed. When adjusting the gas boiler, if the wind speed control of the secondary is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Further, when the adjustment is not timely gas boiler load changes the level of the upper orifice of the secondary throttle will be cooled so that the burner is not burning. After the burner for damage affecting the entire gas-fired boiler it is very large, so users in the usual course of adjustment is necessary to strengthen the control of the boiler, including the timely and quality control gas pressure changes in circumstances, gas and hot air to ensure reasonable ratio; when viewed ignition gas, adjust the size of the second damper, to change the operating angle of the operating layer when necessary; when the low load conditions change, to adjust the negative pressure combustion furnace, adjusting gas, the ratio of hot air, to ensure that the furnace coordination with the flame does not skew the layers of good gas opening. Further, the material can be appropriately improved gas burner in the boiler, it is recommended to select superior steel materials, wear resistant and adding functionality. Selection of swirler vanes refractory steel material, so to avoid burning due to swirling vanes configured fall burner opening deformation damage. In addition, be sure to strict accordance with the drawings need to adjust the gas boiler burners standards to ensure tangential firing flame in the furnace, ensure the stable operation of the gas boiler. On the practical application of gas-fired boiler There are many different applications and different habits, a variety of problems, if users also encountered other problems, you can consult our technical staff, to welcome the advice, we will the attitude of enthusiasm for your service needs.

Details of boiler boiler periodic inspection during operation, the pressure member at high temperature and pressure vapor medium effect at high temperature flames external radiation or smoke erosion, corrosion may occur, deformation, wear, fouling, burnt, leakage and other defects, It will appear fouling, coking phenomenon, if not timely detection and timely eliminate hidden dangers, could result in equipment damage, may lead to serious life and property losses. Visible boiler periodic inspection is very important. According to "Provisional Regulations on Boiler and Pressure Vessel Safety Supervision" and "Steam Boiler Safety Technology Supervision", "Hot Water Boiler Safety Technology Supervision" (hereinafter referred to as "Regulations"), the State Quality and Technical Supervision Boiler and Pressure Vessel Safety Supervision Bureau has developed "boiler periodic inspection rules." Fast boiler for you regarding the removal of an important part of a regular inspection of boilers for everyone to share: fourth regular inspection of boilers includes external inspection, internal inspection and hydrostatic test three types: external test means that the boiler in operating state examination of the security situation of the boiler; 2, internal inspection means to inspect boilers security in a boiler shutdown state; 3, hydrostatic pressure test is a test boiler water as a medium, a predetermined boiler pressure strength and tightness testing member performed. Article boiler external inspection is generally carried out once a year, usually internal inspection once every two years, the general pressure test once every six years. For internal inspection of the boiler can not be, should be pressure test every three years. Internal pressure test and inspection cycle power plant boiler may be appropriately adjusted in accordance with the overhaul cycle power plant. Only when the internal inspection, external inspection and hydrostatic testing are within the acceptable period, the boiler can be put into operation. Article 6 except for normal periodic inspection, the boiler of the following circumstances, the following test should be conducted. External inspection: 1, the start reassembling the boiler put into operation; 2, the boiler stopped running more than a year to recover; 3, combustion and boiler safety automation system after the change. Internal inspection: 1, the newly installed boiler after one year; 2, to move equipment before the boiler put into operation; 3, boiler stop running more than a year before returning; 4, the pressure elements are important repairs or renovation and re-run after 5, according to the results of previous internal inspection and boiler operation, there are doubts about the safety and reliability of equipment;; 6 after a year, according to test results and external boiler operation, safety and reliability of the equipment when there is doubt. Hydrostatic Test: 1, reassembling the boiler before put into operation; 2, the pressure receiving element after major repair or reconstruction. Article VII When internal inspection, external inspection and hydrostatic test carried out in the same period, should be followed by an internal inspection, hydrostatic testing and external testing. Article 8 Units and boiler inspectors engaged in inspection work should qualify the project and the corresponding level in accordance with the relevant provisions of the National Board of Boiler and Pressure Vessel Safety Supervision Agency. Article IX of the boiler using the unit, the unit should be carefully examine the implementation of this rule; Boiler and Pressure Vessel Safety Supervision Organization to oversee the implementation of this rule. Article X boiler unit boiler should be submitted in the prescribed periodic inspection of boiler units before the date of the inspection and periodic inspection applications. Use the integrated test units each test date unit boiler inspection plan worked out, and notify the boiler unit.

Gas hot water boiler maintenance measures which each machine in the course of people's needs with care, otherwise it will cause unnecessary trouble sourcing business. Then for professional gas hot water boiler, how effective maintenance methods? In general use, not only to pay attention to the effect of gas hot water boiler, but also to take some effective measures to improve its service life. 1. Pressure to maintain this repair method is applicable to temporary maintenance outage but no more than one week boiler. First, the water in the boiler exhaust, then cleared up the furnace fouling, then add qualified demineralized water. Regularly with warm fire heating, the gas hot water boiler water temperature maintained at about 10 degrees in summer and winter to ensure that it will not freeze; boiler should pay regularly, the pressure in the boiler is maintained at the normal value, preventing air from entering the steam package. 2. Wet care This method is suitable for repair closing time of no more than one month of gas hot water boiler. After closing the furnace, must be released in accordance with a predetermined water discharging time, to remove impurities furnace; secondly, closing all the inlet valves and holes, so that the operation of the boiler complete separation; and then formulated into an alkaline solution with a special protection boiler mercury. During the entire maintenance, should be periodically heated drying surface, and slightly fire, in order to maintain heated surface drying performance. 3. Dry care Dry maintained for long downtime gas hot water boiler. Need to drain water and to remove impurities, followed by the boiler must be completely isolated in operation; using an appropriate amount of moisture absorbed by the desiccant in the boiler, and require direct contact with a heated surface not desiccant boiler. Within a month, you should check whether the desiccant in the boiler and no corrosion.
