The use of electric 2 ton wns series boilers gradually tends to calm down, because the current market is dominated by gas stoves. Of course, with the development of urbanization in China, electric boilers have become one of the most important kitchen utensils at present. Household appliances kitchen utensils also gradually become a future development mainstream, from the current understanding of electric boilers to the final use of safety analysis, the overall development of electric boilers is still a certain feasibility. The electric boiler has already succeeded in attracting the attention of different people on the safe performance of its use. Only when we pay more attention to the application of the electric boiler will we be more willing to choose the optimal one. The electric boiler uses the standard as the future understanding plan of all kinds of work. The use of electric boilers is based on the quality of their products. As long as this type of boiler equipment can give play to superior quality characteristics in the course of use, the user can use them in accordance with the safe use manual in the course of use. Electrical equipment for kitchen utensils such as electric boilers is safe. No matter what electrical products our users are using, safe use and proper operation are necessary. From the current understanding of the electric boiler, we can also see that all the current understanding of the electric boiler begins with the performance standards for safe use. The electric boiler is currently in use and power generation. The exhibition is also more stable and reliable. Different types of electric boilers are also suitable for different types of households. There are electric boilers suitable for open-air kitchens, electric boilers for rechargeable purposes, and electric boilers with solar panels absorbing and converting solar energy into electrical energy. In short, This is an extremely rich age of commodities. We don't have to worry that we don't have the goods we want to buy.
To conscientiously implement the CPC Central Committee and State Council "on the overall strengthening of environmental protection and resolutely fight pollution prevention advice tough fight" and "the State Council on the issuance of three-year winning the Battle of the blue sky plan of action," the spirit, 2 ton wns series boiler emissions control, prevention and treatment air pollution, the State environmental Protection Department to develop "boiler air pollutant emission standards." In order to further the implementation of air pollution control operations, all regions at the same time meet the national standard, but also have introduced a more stringent local standards.
From the implementation of the Beijing gas nitrogen oxide emission standards for boilers began 30mg, emissions from gas-fired boiler has been of great concern, expand around the "coal to gas" action, so that gas such devices become the most countries to promote clean energy boiler.
The transformation of the current common low nitrogen boiler, there are three main measures: (1) replacement of boilers, (2) replace the burner (3) in the boiler flue gas treatment.
Controlling the nitrogen oxide generated from the source, the most advanced technology on the market today is the use of flue gas recirculation techniques and FGR premix combustion gas boiler technology, both having different focus, low nitrogen emissions boiler.
Replace the boiler burner, renovation and debugging, and the impact on the safety performance of the resulting boiler, burner unit by the responsible manufacturer or his authorized. Beijing Bureau of Quality and Technical Supervision, Beijing Municipal Environmental Protection Bureau issued the "Notice on the transformation of the low - NOx combustion safety risk warning" states: the transformation of low-nitrogen combustion boiler diverse, complex technology, to protect the smooth implementation of the work of reform, effective prevent security risks, prevent accidents, analysis and appraisal by experts, it is not recommended comprehensive safety, environmental factors, the following recommendations:
Nitrogen oxides have been generated by some means and then reduced to nitrogen, the main fuel reburning, selective catalytic reduction, selective non-catalytic reduction. But in the actual monitoring, the nitrogen oxide emissions controllability is poor.
The transformation of low nitrogen gas boiler is a need for long-term adherence and actively manage the work, under the premise to meet the national standards, do specifically address the specific circumstances, not blindly, careless handling, to adopt plans, goals, ideas implementation, to achieve a comprehensive upgrade gas boiler.
Electric 2 ton wns series boiler is an indispensable heating gas in winter, that is, the most important electric boiler is not suitable to place combustible materials (paper, cloth and other combustible materials) around the boiler, which can reduce the occurrence of fire from the source. 2. Electric heaters do not have plugs, plugs forget to be unplugged and resistive wires are overloaded, or aging plugs and cables can also cause fires. 3. When using electric heaters, people should always be kept on the edges, and power plugs should be unplugged when they are not in use. Many people do not have the habit of unplugging the switches, but this will also give a fire a chance of fuelling. 4. If there is a sudden power outage, Unplug the heater to prevent incoming calls A fire broke out with a sudden increase in electric current.
01. Thermal control system classification of fuel-fired gas-fired boiler (1) Electric instrument combination system mainly consists of relay, time relay, program relay and so on, which consists of program control and interlock protection system; The monitoring and regulating system is composed of electric unit combination instrument or digital and intelligent series instrument, measurement and display instrument, acousto-optic alarm instrument and so on. The design experience of electric instrument system is mature and the price is cheap, but it is difficult to realize the redundancy of the system, data transmission and maintenance, and it is also difficult to realize the advanced control method. The electric instrument system is mainly used in the small boiler, but the electric unit combination instrument is used in the closed loop adjustment. The use of cases has been reduced year by year, almost replaced by intelligent multi-functional instruments, The electrical unit assembly instruments mentioned in the following sections are simply intended to illustrate the principle and composition of the regulation system using a series of instruments familiar to the industry and widely used in that era. (2) the core of programmable control system is programmable controller (PLC). The programmable controller has been widely used in logic control at first, and the ability of process control has been increased since 1990s, which makes the application of programmable controller in the field of process control more and more extensive.
Advancing the ignition point of coal, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the 2 ton wns series boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal. 2. The air supply and reasonable regulation. In Grate, vibration stove, oven and forth, depending on the characteristics of the combustion process, reasonable air, to promote combustion furnace is very important. As the chain furnace, with grate the fuel is kept in motion, occur sequentially ignition, combustion, burn various stages. Along the longitudinal direction of the combustion grate stages, the partition, the amount of air required in the grate longitudinal direction is different. In the preheating zone of the head and the tail of burnout grate stage, small air requirement in the middle stage of combustion grate, the air amount required.Free Chat
