oil condensing boiler for wine industry
Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, condensing boiler for wine industry flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
When long-term disabled condensing boiler for wine industry, furnace should pay great attention to external corrosion and maintenance problems. First, the boiler shutdown cooling, heating surface must be thoroughly cleaned and the fouling of the upper grate, the lower portion of the furnace ash. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace.
WNS Gas and Oil Dual Fuel Horizontal Boiler
It is the fire tube dual fuel boiler; the boiler is a sub-project of world band GEF high efficient & environmental boiler project. Cooperated with Germany technology, the horizontal gas & oil fired boiler main technologies have reached the advanced world level. The dual fuel boiler adopts three-pass, wet-back structure, large combustion chamber makes the burning fully. Imported burners such as Weishaupt, Baltur, Riello, etc are equipped to ensure a high combustion efficiency.
What are the three common condensing boiler for wine industry 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.
