pressure switch application in boiler
Maintenance of common gas pressure switch application in boiler you buy boiler equipment, will pay attention to a lot of problems, the number of thermal efficiency, energy saving and environmental protection whether, if the boiler manufacturers have to install special equipment manufacturing license, etc., are all you need to pay attention to the selection of points. But at the same time, the boiler in the course of regular maintenance is also very important. Regular maintenance of the gas boiler, can effectively extend the life of the boiler, improve work efficiency boilers, low failure rate, is conducive to the normal safe operation of the boiler. After regular maintenance gas-fired boiler, life, energy efficiency and the failure rate of maintenance should be carried out regular maintenance of the boiler better (especially boiler has been running for more than one year) than those without. Conventional boiler maintenance methods are: pressure maintenance, maintenance wet, dry maintenance, maintenance inflated. A pressure maintenance using pressure maintenance shutdown time does not exceed one week. Before the system shutdown process terminates filled with water to make soft drinks, is to maintain the residual pressure 0.05 ~ 0.1MPa, boiler water is maintained at a temperature above 100 deg.] C, can effectively prevent air from entering the boiler. Second, wet wet maintenance shutdown maintenance time does not exceed one month. In the soda boiler water softener system cheerful note lye, leaving no vapor space. This is because a stable oxide film with an aqueous solution of a suitable alkalinity can be formed with the metal surface, thereby preventing corrosion. Third, using the dry method maintenance shutdown maintenance time is longer. This is done; pot of water put the net after shutdown, residual heat boiler using a drying furnace, timely removal of residual scale and pot residue was then placed on the tray containing a desiccant within the drum and grate, Finally, close all valves, manhole and hand hole door. Regular inspection and maintenance, and timely replacement of the desiccant failure. Fourth, inflated maintenance Inflatable maintenance shutdown can be used for long-term maintenance. After the boiler shutdown, do not turn on the water, the water level is maintained at the high water line, to take measures so that the boiler deoxidation, then the pot of water and isolated. After the ammonia gas or helium gas through the pressure after inflation is maintained at 0.2 ~ 0.3MPa, nitrogen combines with oxygen to generate nitrogen oxides, so that the oxygen can not be in contact with the steel plate; ammonia was dissolved in water such that the water is alkaline, can effectively prevent oxygen corrosion phenomenon.
Hot water pressure switch application in boiler is one of the important equipment for the district to provide our real estate company, and two gas hot water provide the fast boiler boiler flotilla of environmental performance, in full compliance with state regulations after smoke was detected in the rear of the boiler. And boiler operation is safe, stable, we use the very at ease. --customer feedback
First, pressure and atmospheric pressure switch application in boiler 1 contrast, generally speaking, pressure hot water boiler heating system is vented to atmospheric pressure, so the factor of safety of boiler operation will be relatively higher, basically no phenomenon boiler explosion .
The main task of monitoring and adjusting Henan gas pressure switch application in boiler running Henan gas boiler means to monitor and adjust the operation of its main tasks are: 1. Maintain evaporation within the rating of the boiler, the steam quantity to meet user requirements, avoid overload operation; 2. maintain normal pressure and temperature; 3 balanced water, and maintain the normal water level in the boiler; 4 to maintain steam quality compliance; 5. maintaining good combustion, improve boiler thermal efficiency, and comply with environmental requirements; 6 . ensure the safe operation of the boiler unit. Henan run gas boiler means that the working conditions at the time of boiler operation, it is through a series of operating parameters to reflect. These parameters are referred to as operating parameters, such as vapor pressure, evaporation, evaporation temperature, drum level; flue gas, air, water temperature and pressure; the fuel consumption and smoke components. The main factors Henan gas boiler operating conditions are: the boiler load, and fuel, feed water temperature, excess air coefficient. Boiler normal operation, it must control the water level, pressure, temperature within a certain range to suit the user's own safety and thermal boiler equipment requirements. Excess air ratio influence Henan gas boiler operating conditions for relatively large. Excess air ratio is increased, mainly due to air leakage. The increased excess air, the furnace temperature is lowered, reducing the radiation heat transfer, the convective heat transfer increases, also increases the amount of smoke, heat losses increase, reducing the thermal efficiency of the boiler. At the same time, induced draft fan or blower power consumption increases. Excess air coefficient is determined by each site smoke constituents determined. The efficiency of a combustion analyzer may measure the contents of carbon monoxide in the flue gas, it is determined whether the combustion sufficient to direct fuel ratio adjustment.
