Wns Industrial 2Ton Oil Boiler

Pressure maintenance, wns industrial 2ton boiler pressure exceeds the rating linkage Maintenance: Measures is shutdown, the combustion system to stop working; also be changed fire mouth, single-stage or two-stage combustion, also conditioning oil, then the buck, to ensure the safety of boiler operation. Pressure manipulator: Usually manipulator with two pressure, the pressure signal converted to an electric signal electromechanical conversion device, its function will be the high pressure or low levels of signal to the electrical switch, external circuits actively control or chain protection. Safety valve: safety valve is the last line of defense in maintaining the boiler, when the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler.

What are the three common wns industrial 2ton boiler combustion? Urban coal-fired boiler has been difficult to solve, because especially small coal-fired boilers type cluttered and more widespread particularly difficult to handle. On the one hand burning low power, on the other hand is more a waste of resources. Under the requirements of environmental protection requirements, many cities in the relevant part of the requirements necessary gas (oil) boiler retrofit or replacement of 10t / h coal-fired boilers. The transformation of the former needs to focus attention to the following questions: whether the site is useful region of central heating boiler heating of small alternative program. The useful life and corroded boiler, if the boiler by Zhengzhou fast boiler or other professional testing organization to determine the useful life of less than five years, the transformation of value is not high. Determine whether the laying of gas pipeline convenience, liquefied petroleum gas or other fuel supply and transportation issues. Comparing the cost of renovation and equipment manufacturers advantages and disadvantages, in determining the needs of the transformation plan in compliance with these principles. Selection of fuel. Under the premise of fuel sources have, the most economical natural gas pipelines, liquefied petroleum gas, followed by a final light diesel oil. Also, consider the surrounding environment from fire and explosion safety. In general, the system and the soda boiler pressure parts and preferably not modified to adhere to the original power, are demand, under conditions not substantially change the pressure member, than the original power increased by 10% to 20%. Boiler pressure parts for major changes in the program desirable. The transformation process is necessary to ensure the safety of boiler pressure parts of (mostly small commercial general pressure boilers), followed by incineration system to ensure the safety factor, the decline in the risk of explosion, fire accidents. Recognize the transformation of the planning process, in a timely manner, the environmental protection, the gas company, fire department, urban construction and timely communication with the boiler section to monitor and ensure the transformation plan can proceed smoothly. When the boiler is burning way during boiler selection will take into account an element, the following three common boiler burning approach advantages and disadvantages brief analysis cf: 1 Decentralized incineration strengths: this way is not burning premixed, but the gas nozzle mouth dispersed with each other, and then burning it. Incineration relatively simple way, as more stable as compared to the flame. Disadvantages: Due to a longer flame, it is prone to the phenomenon of incomplete burning, more carbon monoxide and nitrogen oxides will occur, it is not conducive to the use of full-fired boilers, to improve the thermal power of the boiler, and the boiler emissions standards are difficult to reach. 2. premix approaches incineration advantages: premixing air and gas, a multi-way heat radiator, to improve the strength of heat transfer. Strengths of this approach is that the burning of the burning flame is more clear, and the higher heating power. Disadvantages: incineration requires precise ratio premix burning rate is fast, uniform burning radiant heat transfer full power high flame temperature below 1200 deg.] C, all NOx completely burned and the occurrence of low flue gas temperature, condenses, good heat recovery and high power. 3. No flame burning incineration space before incineration approach uniform mixing with the gas in the gas boiler. When using this approach, in the process of incineration gas in the oxygen demand is not made in the ambient air demand, only needs to achieve instant complete incineration air mixture reaches the incineration zone. Approach in the selection of incineration, incineration demand for the advantages and disadvantages of different approaches, carried out mutatis mutandis selection, a good way is also advantageous burning boiler to reach plenty of incineration, thermal power increase, decrease the role of emissions, and therefore, it is important to choose carefully.

The level of development of the industry and domestic and international comparative analysis gap - burners, wns industrial 2ton boiler and burner systems to control and standardization in foreign countries, the company has successfully developed and promote the use of conventional fuels, including premixed combustion, low NOx combustion technologies, including and unconventional fuels one-piece, split burner products, the largest single power split reach 93MW, monolithic reached 14MW. By using an external flue gas recirculation techniques, internal flue gas recirculation techniques, staged combustion air or fuel staging techniques, flue gas denitrification technology, premixed combustion technology + flameless combustion, the burner nitrogen oxides (of NOX) and boiler nitrogen oxide emissions to a minimum of about 5 / 10mg / m3. Technological development burner of a relatively short history, only five, six years, although from the beginning of imitation but higher than in Europe and other industrialized areas starting point, "five-second" period is entering the period of rise development, product varieties increased rapidly, product quality has greatly improved, especially the steady growth of production and application of non-conventional fuel burners. But it is undeniable, domestic and foreign brands burner there is a certain strength of the gap: ① low NOx combustion with low nitrogen emissions burner domestic enterprises has just begun to address, because there is no boiler manufacturers involved in this industry burner, and more Needless to say, carry out research and development of low NOX burner. ② R & D capabilities in the oil and gas burner and means in Europe and other developed countries, each burner manufacturers have their own R & D test center, and provided strong support for the development of the burner technology. Looking at the top ten manufacturers of our country, in addition to individual enterprise and some simple test bench, most lack a comprehensive, scientific instruments and test equipment as well as related technical professionals in research and development. In a related colleges and universities is also a lack of such research tools. ③ in the production of marketing products overseas burner large burner vendors have implemented mass production, from procurement and manufacturing cost control and marketing and other parts have a very big advantage, resulting in domestic conventional fuel burners competition in the market force is obviously inadequate, domestic burners companies are non-standard products as a breakthrough in the market, it is difficult to form large-scale production.
