Matters needing attention in use of condensing Boiler

Condensing boiler can recover heat from boiler smoke and latent heat of steam condensation in flue gas to improve service efficiency of condensing boiler and reduce harmful gas in flue gas. So it will soon become the future development direction of boiler technology. Driven by this new form, consumers also buy condensing boilers in succession, so in the use of condensing boilers, what aspects do consumers need to pay attention to in the use of condensing boilers?

1. pay attention to cleaning: in the cleaning process, the main role of the pickling inhibitor is to prevent metal corrosion during pickling of condensing boilers, in most cases, Many people choose to use their eyes to test the cleaning of condensing boilers. However, visual inspection can only see whether the cleaning is clean, ignoring the most important indicators of cleaning-the corrosion rate and the amount of corrosion. The rate of corrosion and the amount of corrosion is invisible to the naked eye. Therefore, consumers should also know how to measure the rate of corrosion and the amount of corrosion; in the cleaning process, the use of down-in, up-out or up-in-out circulation mode, the installation of temporary cleaning circulation pipeline in multiple locations, so that the pot barrel, Steam drum, pyrotechnic pipe, riser pipe, drop pipe and header can be circulating by cleaning pump to keep the concentration of cleaning fluid balanced, which will enable insoluble matter to be discharged from the boiler after cleaning. So as to prevent a large number of dirt from falling off and accumulating, resulting in boiler "tube explosion" accident.

Structural Advantage of WNS Hot Water Boiler

1.Reasonable design: horizontal internal combustion three return all wet back design,100% corrugated furnace, with good heat flexibility. The water covers fire overall design, sufficient heating area, make sure the boilers high efficiently operated.

2.Fully automatic operation: Users simply start the button, boilers can run on the setted program. The load of water saving, water supply, etc. are fully automatic operation, no need for guard in position.

Gas heating boiler operation and management system to resolve the gas heating boiler heating system will be relatively complex, requiring a strict management system to ensure safe heating boiler running smoothly in this process need to pay attention to the following points: 1. The quality of boiler water must to go through rigorous testing, sub-standard water to be softened to avoid scaling, corrosion and other boiler components after use, affecting the thermal efficiency and operational safety late boiler. 2. boiler and its auxiliary system is operating normally, if abnormal timely feedback process. 3. Ensure the indicators boiler water systems, safety accessories and other normal and flexible. 4. boiler operator rigorous specialized training and work and strict management system, be sure to do, patrol officers and operators keep alert, can not be insensitive. Inspection time designated times to be once per hour. Period of time to carry out maintenance and repair timely 5. boiler shutdown. To ensure that the boiler inside and outside the normal indicators, the device remains clean and orderly. 6. In addition, during each inspection of boiler operation, inspection, etc., must do text and data records to ensure that when the transfer of work to be a clear understanding of boiler operating conditions between the transfer of personnel. Of course, the normal norms of these will be far more complex, these are the general direction in which, in any case, to ensure safe operation, the safety of gas heating boiler, while maximizing operating results play a boiler, strict implementation of the operation and management system It is a necessary operation.
