6 3mw hot water boiler
Around the low nitrogen emissions and thermal efficiency of the boiler regard, Jiang Zuojun, who are very interested in the company's showroom will watch the animated presentation, could not help nodding in approval, other fast boiler in a variety of achievements in the industry made a lot of money and gave high praise and affirmation. Subsequently, a pedestrian visited the lab to clean the boiler group, for the constitution and the implementation of the Group's research laboratory work was questioned and understanding.
By the mid-1980s, energy prices and enhance the development of materials science and technology told, there has been recuperative condensing technology. A high temperature flue gas and water are not in contact, the intermediate thermally conductive corrosion resistant material. Condensing boiler is currently the most of the technology used. Describes a low temperature heat exchanger corrosion after conventional boiler air and gas mixing, heat is obtained by combustion, flue gas discharge temperature of about 170 ℃. Flue gas containing water vapor, CO2, steam sulfate. Since natural gas inevitably contains a sulfide, after combustion of SO2, produced of SO3 (accounting for about 5% SO2) is oxidized after the combustion continues. SO2 is combined with water to generate sulfite, SO3 combines with water to form sulfuric acid, the acid dew point temperature of about 140 deg.] C to 160. deg.] C (depending on the content of SO3 lift). When the exhaust gas temperature at a conventional boiler 170 ℃, gaseous sulfuric acid vapor does not produce significant corrosion of the main heat exchanger. When the latent heat of the flue gas collection (the exhaust gas temperature is reduced to 50 ℃), will produce a strong acid corrosion of the main heat exchanger. And the corrosion occurs mainly in heat exchange contact surface area lower temperature, referred to as low temperature corrosion. Can be achieved at low temperature corrosion serious 1mm / year perforation caused by the contact surface, the current science and technology still can not avoid low temperature corrosion, can only minimize.
the control system of the horizontal gas fired boiler
Due to the rapid explosion of the gas and the polycrotism of the its load, the gas fired boiler should adopts self control system.the main task of the self control system are maintaining the boiler’s water level,temperature, pressure, smoke oxygen content within a standard level and adopting it self to the load change.
Electric steam boiler exhaust smoke temperature rises, then it should be because the pipeline rupture caused by electric steam boiler, the solution is to pipe water shortage caused by electric steam boilers quickly repaired, or to replace a new pipeline.
