mpc based boiler tutbine unit control

Most gas-fired mpc based boiler tutbine unit control is installed in the boiler room, there is little left outdoors, outdoor use, and this is one way to protect the boiler. So, when building gas boiler rooms and internal structural arrangement, what are the precautions it?

The method of chemical plant mpc based boiler tutbine unit control safety inspection method which chemical plant boiler safety inspection of which 1, the basic test. In fact, there are a lot of boiler safety inspection method, in general, most of the inspectors usually use their own senses to test, which is the basic method of testing, mainly through seeing, hearing and other senses to recognize the quality of the boiler, to see whether it occurs deformation, etc. Therefore, application of this method often requires inspectors be able to have some work experience, so as to better meet the requirements of the job. 2, the use of tools for testing. Using tools to test is the more common test methods, compared with the basic test methods, the use of tools such way is more scientific and accurate, especially if it is to carry out in-depth examination, we need to use some tools, so as to ensure the accuracy and reliability of test results, the better to promote the smooth progress of inspection work. In practical terms, most of the time, people are more accustomed to using a small hammer to test, you can tap to check all parts of the boiler, the staff felt, etc. can be fed back to identify the defects, loosening problem. So, again, it also requires quality inspectors can cross the border, with a certain level of expertise is essential. In addition to a small hammer, you can use a ruler to quality testing and other tools.

Your steam mpc based boiler tutbine unit control is running properly, look at the work of the water table, right: in a steam boiler, the water level in the boiler to detect whether the table is the basis for safe and stable operation; real-time display of boiler water level, dynamic monitoring internal boiler so that the boiler water level control in the normal range. In many cases, the water level by looking at the table working condition, you will be able to determine the steam boiler is running properly. Therefore, each of the following safety testing method is particularly important. 1, each steam boiler at least two water table, ensure that they can be used normally. 2, where the water table mounted easy to observe, illumination must be provided. 3, operation of the ground water table from above 6m, the remote installation of the water level display device. 4, direct-reading water meter must be clearly marked to ensure the highest and lowest security level and normal water level (red bar) during normal use of the water table. 5, the lower portion of the visible edge of the water table is lower than the minimum security level at least 25mm, at least higher than the upper edge of the visible maximum safety level 25mm, normal water level in the middle of the table. Second, the method proper operation of the water level in Table 1, the water level table clearly show the normal water level, wash at least once per shift, to prevent false water level; 3, the water table has drainage valve, and a discharge pipe to a place of safety; 4, water table drum soda connection between the valved pipe, the boiler must be run when the valve in the fully open position; 5, soda water table between the drum and the inner diameter of the connecting pipe is not less than 18mm, the inner diameter of the glass tube and water gauge valves flow channel diameter is not less than 8mm.

Inside the Fangkuai mpc based boiler tutbine unit control plant, there is a special corrugated furnace bladder production line, which can be processed according to the computer setting mode. At the same time, this is also a unique processing technology of Fangkuai Boiler. The cost of natural gas fuel alone exceeds 5 million yuan per year. The corrugated furnace liner fired by this production line can not only increase the heating surface of the boiler, but also alleviate the damage caused by the thermal expansion and contraction to the combustion chamber, and greatly extend the service life of the boiler.

Extended state observer based fuzzy model predictive control

Since model predictive control (MPC) can naturally deal with multivariable and constraint issues in an optimal way,,,, it becomes one of the most prevailing techniques in the area of boiler-turbine unit control. In, a MPC based reference governor, which yielded shaped reference for the individual PI controllers, was proposed for a 160-MW oil-fired drum-type boiler-turbine unit. The tracking performance was greatly improved by explicitly taking into account the constraints and
