Incinerator is a general term of assembly that makes fuel and atmosphere eject mixed incineration in an inevitable way.Incinerator according to the example and the use of the platform of industrial incinerator, incinerator, civil incinerator, special incinerator several.Multi-purpose stainless steel or titanium metal corrosion resistance, high temperature resistant materials made.The purpose of the incinerator is to atomize the sample through flame burning.The atomized test solution comes into the incinerator, and a large number of ground state atoms and partially induced atoms, ions and molecules occur through drying, melting, evaporation, dissociation and other processes under the flame temperature and flame atmosphere.A well-planned incinerator should have the functions of atomization, low noise and flame consolidation, so as to ensure high absorption vividness and determination of tightness.Atomic absorption spectroscopy is often used in the fissured incinerator to generate atomic vapor.According to the use of fuel and fuel fuel varieties, incinerator crack length, width are different, the ordinary incinerator are marked with suitable fuel and fuel.

Large water tube boiler, FGR recycle flue gas and fresh air mixed with common configuration mixing bellows.According to the difference of placement position, it is divided into pre-premix and post-premix.Pre-mixing is the mixing bellows placed in the blower before, after the inclusion of reincarnated smoke and fresh air, in the air blower, was sent to the incinerator intervention incineration, in the mixed air in the air duct before the air blast configuration trap, crowd out condensate water, fan selection should also choose anti-erosion fan.After premix, after the mixing bellows are placed in the blower, the regenerated flue gas is sent to the mixing bellows after being regenerated. After mixing with the fresh air from the blower, it is sent to the incinerator for incineration.The commissioning condition of the blower is superior to the pre-premixed condition. However, a large amount of condensed water will occur in the air duct, so that a steam trap should be configured at the low point of the mixing bellows and the smoke air duct.
Adhering to the control system is our fidgety today really controls excellent control mode is put forward, in Tessie has been broad used, a little scope sex industry in our country and request the high prices were selected are the control point of view, the focus of philosophy is to asphalt compound floor and burning control equipped with the unified ate all the way, a precise digital control, this control mode from the original master harm, such as: evacuation, incompatible, more comprehensive control, not economic topic.
The benefits are clear:
Optimize the compatibility of software, the unity of electronic control, greatly improve the control accuracy, and save energy
Build in a consistent, safe and reliable manner, and build in a frugal manner
Pure man-machine world faces words
Control system critical
Improved controllability, improved safety coefficient
Pure professional debugging, safe and efficient
One-stop maintenance service without consistency, greatly improved things to obey, for the user low service without the old
One-click accessories, software, to provide access to guarantee
From the perspective of heat exchange calculation, it is necessary to increase the heat exchange surface, improve the heat exchange compliance of the heating surface, improve the heat exchange temperature difference of the cooling source at a lower temperature, and reduce the influence of erosion on the heat exchange compliance.As gas steam kettle host start burning furnace volume and content low nitrogen flame size request, the second host of convection heating surface is a main export to low smoke temperature, average in 150 ~ 250 ° C, in order to survive the smoke temperature is too high growth together with the difficulty of flue heat preservation plan, smoke temperature is too low will cause wall condensation in furnace convection heating surface lead to erosion, therefore, proper heating furnace domestic demand plan, the physical dimension more representative chamber size.To increase the heat exchange surface, it is important to think about increasing the heat exchange area of the building at the end of the boiler, which is more beneficial to the rapidly lowering smoke exhaust temperature.Second, the lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, it can accept the construction of corrosion-resistant materials and improve its service life.The new layout of efficient heat exchange must adopt the modes of staggered tube arrangement, efficient heat exchange finned tube and plate heat exchanger, increase the smoke disturbance and battle surface, reduce the smoke stratified heat resistance, advance medium and smoke heat exchange compliance.
Generally speaking, the building belongs to the hardware of energy-saving base, but the double important is the human element, a good management team, may exercise good people to control every joint, in the operation of every energy-saving factor, continue to summarize the progress of the management and control of the team, this is the software.And an energy-saving management operation in the face of the company, not only face up to the construction of hardware and software in the face of more construction, they are supporting control high-grade attached to the machine control system, good appearance, have been supervised exercise the global flow very get really running data, attached to the machine system in a happy place, in the promotion of the artificial intelligence technology, will the parties face into the dispute machine in the French concession mind and exercise of new means of science and technology take the initiative to control each node, cut salaries turnovers, missed, accurate control the economic system running in high efficiency and energy saving status forever, with is,A comprehensive, reasonable and excellent computer control system is a very good object for human management.
Energy saving is a general project, each node should be controlled, the enterprise needs to invest a large number of manpower and material resources, the enterprise will continue to improve the degree of management, but also continue to harvest energy saving and consumption reduction efficiency, create better economic benefits.
