Most of the boilers needed by industrial and mining enterprises in production are steam boilers. Steam is mostly used in production where a certain temperature of heat is required to meet the requirements of the production process, such as textile printing and dyeing, food sugar, rubber paper, petrochemical and other industries. Therefore, it is necessary to determine the saturated steam parameters of the boiler in accordance with the requirements of the production process. The advantage of saturated steam is that it can ensure a constant temperature required for production.HIGH PRECISION CNC LATHE Generally, the pressure of the boiler is always higher than the saturated steam pressure required for production, the reason is to overcome the pressure loss in the pipeline or pipe network. At present, in many cases, the boiler nameplate pressure is much greater than the pressure required for production. For example, many users have purchased a 13-pressure boiler, but actually only use the operating pressure of 5 gauge or 6 gauge. Running at such a low pressure has adverse effects on steam quality. Because the pressure decreases, the specific volume of the steam increases, and the flow rate at the outlet increases greatly, so that the phenomenon of steam carrying water increases. Generally, the pressure required for actual production plus the pressure drop required to overcome all pipeline resistance plus 25% to 30% of the pressure margin is enough.QK1212/QK1219 CNC PIPE THREADING LATHE The head of the feedwater pump is matched with the nameplate of the boiler. The actual operating pressure of the boiler is too low, and the power consumption of the feedwater pump is obviously a huge waste.Research on Vacuum Brazing Technology of Ceramic and Metal The boiler steam parameters used in small power plants can be configured according to the parameters required by the steam turbine. Most of them use superheated steam at 25 gauge atmospheric pressure. If the turbine is superheated steam with 13 gauge atmospheric pressure, then the boiler should choose the superheated steam parameters with 16 gauge atmospheric pressure, which can make the steam quality better.Heat treatment process of gear vacuum carburizing and quenching
