The incinerator is a kind of assembly of radioactive fuel and atmosphere inclusions. According to its example and application platform, the incinerator can be divided into industrial incinerator, civil incinerator and external incinerator. It is made of corrosion-resistant and high temperature resistant materials of multi-functional stainless steel or titanium metal. The function of the incinerator is to atomize the sample through flame incineration, and the atomized test solution will come into the incinerator. Under the action of flame temperature and atmosphere, a large number of ground state atoms and a few initiating state atoms will occur through drying, melting, evaporation, dissociation and other processes. A planned superior incinerator should have the characteristics of high atomization, low noise, and flame consolidation, so as to guarantee the measured high Absorb vividness and high precision. In the case of difference between gas absorption and help gas, gap incinerator is often used in atomic absorption spectrometry to generate atomic vapor. Gas, incinerator gap length and width difference. At ordinary times, suitable gas and help gas are indicated on the incinerator.
The incinerator is a heat energy assembly which can convert chemical energy into heat energy and master and adjust the burning and conversion process of fuel. The first incinerators in the world can be traced back to the middle of the 19th century, when natural gas was used as industrial fuel. In the middle of the 19th century, people fed back atmosphere or steam and coal to produce coke or charcoal of artificial gas with low calorific value at high temperature. This artificial gas consists of carbon monoxide and hydrogen, while the rest, such as carbon dioxide and nitrogen, are high in content.
In addition to meeting the requirements of relevant standards and construction plan drawings, the installation position of the fan shall guarantee the normal operation and easy protection of the assembly.
During the installation process, the breeze pipe of the initiating fan shall be soft continuous (flexible material and non incineration), the length shall not be less than 200 mm, and the pipe diameter shall be similar to the size of the fan inlet and outlet, so as to ensure that the soft continuous will not be deformed in the system process. During commissioning, the installation shall be controlled and precise. The diameter of the flue gas duct at the outlet of the fan can only be increased, not reduced. If there is a soft and continuous air guide plate, attention shall be paid to the air flow deviation.
The air pipe between the incinerator inlet and the air pipe also starts to accept the soft continuity. The air pipe between the fan and the incinerator shall be connected with a certain angle, and the vertical installation is not easy to cause combustion asymmetry and vibration. The fan at the air inlet is generally an adjustable door, and the arrangement of the inlet baffle shall pay attention to whether the diversion deviation caused by the blade angle is the same as the impeller torsion deviation when opening.
The integrated control system is an excellent control mode that we put forward earlier today. In a few industries in Taixi and our country, enterprises are requested to select this control concept. Its focus is to program the control of the boiler and the incinerator in the same way, and hold a precise digital control. This control mode avoids the disadvantages of the original control methods, such as evacuation, incompatibility, and multiplicity More punishment, economy and other questions.
Its superiority is self-evident:
Software compatibility optimization, electronic control symmetry, greatly improving control accuracy, energy saving and consumption reduction
Plan and production are equal, safe and reliable, and production is old and thrifty
Single man-machine interface temporary call
Operating system intuition
Improve flexibility and safety
Single professional debugging to ensure safety and efficiency
The one-stop maintenance service has no continuity, which greatly improves the obedience of things and lowers the user's service cost
Guarantee one key accessories, software and promotion
From the perspective of heat transfer calculation, the paper explains the missing of low exhaust gas temperature from the aspects of increasing heat exchange surface, improving heat exchange compliance of heating surface, accepting lower temperature source and improving heat exchange temperature difference, and reduces the impact of erosion on heat transfer compliance. Because the main engine of the gas boiler starts to satisfy the volume and size requirements of the low nitrogen flame furnace, the convection heating surface of the second main engine is the critical outlet. In order to lower the flue gas temperature, it is generally controlled at 150 ~ 250 ° C. in order to avoid the rise of the flue gas temperature with the increase of the planned insulation difficulty, too low high flue gas temperature will cause the erosion of the convection heating surface in the furnace
