Boiler steam pressure fluctuation value allowed
Selected boiler steam pressure, depending on the needs of the user. Steam pressure, the safety of the pressure member advantageously, the energy consumption is reduced, but the quality of steam produced will be relatively poor, a low enthalpy. Humidity, difficult to meet some of disinfection, sterilization, farming, heating and power generation needs. High energy consumption is high vapor pressure, corresponding steam equipment, piping and valves the pressure is high, the maintenance requirements will be more stringent. Steam production, heat leak during transportation losses will increase. Meanwhile, high-pressure steam as the steam pressure is increased to carry the increased salinity, the salt will waterwall tubes, pipe tobacco, and other drum heating surface fouling, the possibility of overheating, bubbles, increased clogging even squib . Salt steam to steam turbine flow area will decrease, reducing the efficiency and seriously affect the heat transfer efficiency.
Oil-fired manhole coverkets dimension boiler steam to start the program in the previous article we introduced a program to control the relevant requirements of the first auto-ignition process of oil-fired boilers, meet us on the basis of a second to explain it part of the program control. Program control is divided into start, normal operation, normal stop three parts namely: (1) before starting the purging fire a little bit sparking a fire flame monitoring. Work (2) oil-fired boiler (3) a flame monitoring a low load pressure, temperature monitoring a large, converted a small fire start and stop automatically convert a load adjustment. (3) Normal After purging a fuel cut stopping the program returns to a zero position. These are dynamic program of three major oil-fired boiler, hope can help you. Oil-fired boiler cleaning solution before the oil-fired boiler cleaning boiler must be based on the actual situation, formulated cleaning solution from the professional and technical personnel, and approved by the technical director. Cleaning solution should include the following: (1) Name of boiler, boiler model, registration number, age and put into operation last pickling time; (2) the presence of defects boiler; (3) boiler fouling or corrosion conditions , including scale distribution, thickness (or the amount of sediment), and equipment status scale analysis; (4) washing the scope, the cleaning process; (5), the cleaning process and small scale test material ,, the amount of oil-fired boilers and boiler structure concentration, determined cleaning system cleaning agents, corrosion inhibitors, and other additives of passivating agent, dosage and washing temperature, time and other conditions; (6) chemical cleaning system of Fig; (7) need to be taken boiler cleaning section flow, isolation, protection; (8) the process of cleaning the boiler, monitored and recorded should project; (9) the cleaning process waste liquid discharged; (10) after the washing or cleaning residual dirt cleaning, quality inspection washing conditions. Boiler chemical cleaning should be strictly enforced wash program, if there are special circumstances need to change the program, should sign an agreement approved by the technical director of the original program. To ensure the safety of oil-fired boiler equipment, in strict accordance with relevant cleaning system to carry out.
How to choose more gas steam manhole coverkets dimension boiler steam and medium-sized energy-saving equipment natural gas gas steam boiler in fact belong to, how such a medium-sized energy equipment selection, can save more without it affecting the use of effects a change to follow the season change the setting gas steam boiler has two types of heating and domestic hot water operation mode, winter mode two species are able to choose the public, after the hot water in winter mode can be selected only Volkswagen. Second, when the frequency of each narrow inlet closure closes the inlet, it will follow a substantially gas steam boiler start, start each outbreak substantially better hysteresis. And this runs each repeated outbreaks of high temperature water loss. Third, appropriate room temperature is substantially 20 degrees is good room, sleeping more appropriate to 17, normally open gas steam boiler in winter, the temperature difference between the temperature will be able to fit into the appropriate, the assembly should not be too high. Be sure to use a lot of attention in the way described above, gas steam boiler, and the need to understand the maintenance, overhaul and maintenance time can increase the life of a very large gas steam boiler.
November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast manhole coverkets dimension boiler steam - premix wing-type vacuum condensing hot water boiler, with ultra-low nitrogen oxide emissions and excellent energy-saving effect with this honor. "Energy saving" was first presented in the "" Eleventh Five-Year "Plan", the entry point to do by reducing energy waste and reduce emissions in terms of both economic development and adhere to common development and environmental protection. Since 2015, the state has increased efforts to promote energy-efficient technology and equipment, mechanical and electrical products each year in all types of energy-saving aspects of the work of judges, party fast with a strong technical ability to create many types of environmentally friendly products, as the heavy regulars honor.
