biogas fired steam boiler pvc plant
Utility Boiler works: the role of the boiler fuel chemical energy is converted into thermal energy, heating and heat inside the pot with water to become superheated steam having a mass and a sufficient amount (steam temperature, steam pressure), the turbine used for . Now the power plant boiler capacity, high parameters, technical complexity, high levels of mechanization and automation, the main fuel is coal, and coal prior to combustion of pulverized coal first made, and then into the boiler combustion heat release in the furnace. Broadly speaking, the work process is the main boiler fuel combustion, heat transfer, vaporization and heating of the water with the superheated steam and the like.
The installation of pressure gauges for Fangkuai boilers depends first on the pressure point and the space position of the pressure gauge (or pressure transmitter), and then on what pipeline accessories there are and how to lay them. (1) in order to measure the static pressure correctly, The extraction port must be perpendicular to the medium flow. No chamfering, flanges, and burrs. When measuring the liquid pressure, the pressure-taking port shall be drawn from the lower part of the pipe section, so as to prevent the gas in the liquid from entering the pressure-guiding line; When measuring the gas pressure, the pressure-taking port should be drawn from the top of the pipe section to prevent dust in the gas and water droplets from entering the pressure-guiding pipeline. (2) the inner diameter of the pressure-taking pipe is usually φ 7 / 1. 3mm (for water, steam), its length should not be too long (< 60m). If the diameter and length of the pressure-taking pipe are too small, the dynamic transmission of pressure measurement will be affected and the dynamic error will be increased. The inner diameter is too large, not easy to maintain and install. The pressure-taking line shall not be laid horizontally in order to prevent the accumulation of bubbles (when measuring the liquid) and the water column (when measuring the gas). (3) the pressure-taking line must be fitted with a needle-shaped valve (to cut off the pressure in the event of failure of the pressure-taking line in operation), Secondary needle valves (instrumentation, stop, replacement), condensing coil and elbows (isolation elastomers from high-temperature heating in the medium and easy to install sealing patches); and Sewerage valves and sewerage lines, etc. For special pressure measurement, the pressure taking line must also be equipped with vent valves, isolation rooms, etc. (4) the installation site of the pressure gauge (pressure transmitter) shall meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, At the same time, it should be easy to observe, repair and ensure safety. The pressure-taking pipeline of high-temperature medium must be coated with a thermal insulation layer to avoid scald when punching the tube.
Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing biofired steam boiler pvc plant, and is responsible for subsequent transportation, installation and commissioning work .
How future trends gas boiler kind: combined with social development of China's energy situation and adjust their strategies into the market after the gas boiler has been widely spread and use. So, combined with the actual situation now, how about reputation of a good gas-fired boiler in the future development trend?
