Factory Price Best Selling Horizontal Fire tube Steam Boiler
1, the general position of the explosion vent means in the top wall or the steam outlet of the boiler furnace furnace furnace side of the fuel gas flue.
2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters.
Steam boiler in the winter should pay attention to what things? With the advent of cold weather in winter, factory price best selling horizontal fire tube steam boilers also need to experience problems in running operation, it is time today for everyone to share a steam boiler in the winter should pay attention to what matters. Yesterday received two calls from customers saying steam boiler water level of the cracking, as the weather cools, we should pay attention to maintenance of steam boilers, boiler deactivated after the boiler should wait until after all the pressure and then discharge the water in the boiler all vented to avoid boilers and boiler pumps and accessories freezing, remember must take the water pump and the water level inside the water all let go.
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 partnership, fast boiler for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback
