What are the relevant norms and standards for refuse derived fuel RDF fuel projects?

At present, there are no corresponding norms and standards in the country and industry, but there is already a technology to make RDF, which can generally be classified according to the standards of the United States, and the United States (ASTM) divides RDF into 7 categories according to the degree of processing, shape, and use of municipal solid waste-derived fuels

RDF-1 is a combustible solid waste obtained by removing bulky waste from ordinary municipal solid waste.

RDF-2 Combustible solid waste obtained after removing metal and glass from domestic garbage and coarsely crushing through a 152mm sieve (coarse) RDF-3 Combustible solid waste (fleece) obtained after removing metal and glass from domestic garbage and coarsely crushing through a 50mm sieve

RDF-4 removes metal and glass from household garbage, coarsely crushed through 183mm of combustible solid waste (powder) obtained after sieve

RDF-5 sorts out non-combustible materials such as metal and glass, crushes, dries, and processes combustible solid waste (fine) from domestic waste

RDF-6 processes household waste into liquid fuel.

The RDF-7 processes household waste into gaseous fuel.

China's prior art is generally to make RDF into RDF-4 or RDF-5 more, and some also add a certain amount of coal to keep the calorific value constant and make the combustion stable.

There are no specific standards yet, they have always been in the research stage, and China has just started. You can refer to the requirements of air pollution control of garbage incinerators. Of course, there are successful cases, such as Huaxin Cement Wuxue Company, which is RDF that produces cement, and it is very successful.

Then there are too many of them, and the most common ones are some medical equipment, such as blood pressure monitors, blood glucose meters, and so on!

With the continuous development of microelectronics technology, VLSI chips (i.e., microcontrollers) that integrate circuits such as CPUs, memories, timers, counters, parallel and serial interfaces, watchdogs, preamplifiers, and even A D, D A converters on a single chip have emerged. With the single-chip microcomputer as the main body, the computer technology and measurement and control technology are combined to form the so-called "intelligent measurement and control system", that is, intelligent instruments.

Compared with traditional instrumentation, intelligent instruments have the following functional characteristics:

Operational automation. The entire measurement process of the instrument, such as keyboard scanning, range selection, switch start-up and closing, data collection, transmission and processing, display and printing, etc., are controlled and operated by single-chip microcomputer or microcontroller to realize the full automation of the measurement process.

It has self-test functions, including automatic zero adjustment, automatic fault and status inspection, automatic calibration, self-diagnosis and automatic range conversion, etc. The smart meter can automatically detect the location of the fault or even the cause of the failure. This self-test can be run at the start of the instrument, as well as during the operation of the instrument, greatly facilitating the maintenance of the instrument.

With data processing, this is one of the main advantages of smart instruments. Due to the use of microcontrollers or microcontrollers in smart instruments, many problems that were difficult or impossible to solve with hardware logic can now be solved very flexibly with software. For example, the traditional digital multimeter can only measure resistance, AC and DC voltage, current, etc., while the intelligent digital multimeter can not only carry out the above measurements, but also have complex data processing functions such as zero point translation, average value, extreme value, statistical analysis and other complex data processing functions for the measurement results, which not only liberates the user from heavy data processing, but also effectively improves the measurement accuracy of the instrument.

Friendly human-machine dialogue ability. Smart instruments use a keyboard instead of a toggle switch in a traditional instrument, allowing the operator to simply enter a command through the keyboard to achieve a measurement function. At the same time, the intelligent instrument also tells the operator the operation status, working status and processing results of the measurement data in time through the display screen, making the operation of the instrument more convenient and intuitive.

It has the ability of programmable control operation. Generally, intelligent instruments are equipped with standard communication interfaces such as GPIB, RS232C, RS485, etc., which can be easily combined with PCs and other instruments to form an automatic measurement system with a variety of functions required by users to complete more complex test tasks.

The intelligent automatic carbon and sulfur analysis instrument is used in conjunction with the electric arc furnace (tubular furnace can also be selected), which can quickly and accurately determine the content of carbon and sulfur in steel, iron, alloy, non-ferrous metals, cement, ores, catalysts and other materials.

Analytical instrument testing equipment is a set of optical, electromechanical, computer, analysis technology equal to one of the high-tech products, with a wide range of measurement, strong anti-interference ability, complete functions, easy operation, accurate and reliable analysis results and other advantages, is the ideal carbon and sulfur analyzer for the determination of carbon and sulfur in many industries.

Traditional instruments generally use simple electronic circuits to convert measurement data, display or read out test data in intuitive direct reading mode, without data storage and processing functions, and need to be calculated and compared manually to obtain measurement results. It can only be used for data measurement with low general measurement accuracy, and because of its relatively low cost, it still has a certain market.

A smart instrument is an intelligent instrument with a microprocessor or a microcomputer. It converts the measurement data through the electronic circuit, stores the calculation logic judgment of the data, obtains accurate measurement results through the fully automated operation process, and outputs the text results through the printer. Intelligent instruments have now been widely used in precision measurement in electronics, chemical industry, machinery, light industry, aviation and other industries, and have played an important role in improving the detection means of product quality in China's manufacturing industry.
