29MW coal fired CFB hot water boiler

Our horizontal CFB steam boiler for sale has various types: coal fired CFB steam boiler, biomass fired CFB steam boiler. This basic mode of operation is found in most every steam boiler, but there are a few modifications that have been created for different purposes. A superheated boiler takes the standard process and further heats the steam, increasing the temperature and energy output, and it commonly is used to rotate large turbines. Water tube boilers replace the large tank with a series of water-filled tubes that can reach boiling faster and give off more steam.

The only example of an ultra-low nitrogen oxide emissions through boilers Enterprise Test - fast boiler, the production of gas 29mw coal fired cfb hot water boiler, gas steam boiler, condensing boiler integrated, NOx emissions is far below the required standards, environmental protection departments successfully passed the test and get the user's praise.

6 tph WNS condensing gas-fired fire tube boiler project for chemical industrySichuan New Torch Chemical Co., Ltd. is mainly engaged in the research and development of hydrogen isotope products, providing safe, stable and high-quality products such as heavy water, deuterium generation reagents and high-purity hydrogen sulfide to the national defense cause. The production process of these chemical products is inseparable from the steam heat source provided by the boiler, which is one of the main power equipment on its production line.In the face of increasingly serious environmental pollution problems, China has continuously promoted the "coal to gas" policy. New Torch Chemical actively responded to environmental protection policies and decided to introduce steam boilers that use clean energy as fuel. After understanding the demand and actual working conditions of Sichuan New Torch, ZOZEN recommended WNS series condensing gas-fired steam boiler. This series of gas-fired boilers adopts the structure of single drum, vertical type and wet back, which is safe and reliable. The combustion chamber adopts a large-diameter corrugated furnace to ensure full combustion of the fuel. With the advanced low NOx burner, it is easy to achieve low emissions of NOx ≤ 30mg/m³. In addition, ZOZEN installed energy-saving equipment at the tail of the flue according to the actual working conditions, so that the boiler thermal efficiency is as high as 98% or more, which is 5% higher than the similar boiler system on the market. Besides, the packaged characteristic of the boiler greatly shorten the installation cycle and reduce the installation cost.

Important preconditions on the boiler flue gas dust removal and desulfurization process design engineering boiler flue gas dust removal and desulfurization project is constantly improving our air quality and reducing acid rain PH value. This article will focus on an overview of the relevant boiler flue gas dust removal and desulfurization project elaboration, analysis related to boiler flue gas dust removal and desulfurization process design engineering, to provide reference for China to improve environmental standards. Overview of related dust and sulfur dioxide in the flue gas dust removal and desulfurization project 1 boiler is the main material damage caused by acid rain and the atmosphere, and it is a form of sulfur dioxide is not a harmful gas has a color and pungent, severe cases can damage the atmosphere structure, resulting in environmental change. Not only that, people living with the process of the production process will produce some harmful dust and sulfur dioxide gas, once the proportion of air in these components is too high it will endanger people's health. But also pose a serious hazard to respect people's productive activities, industrial production, construction and so on. Boiler is an energy conversion device, the input energy to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output have a certain outward heat, hot water or organic heat . Boiler is one of the main tools of our country's major industrial production, which will use special means to go after some of the energy input material must be converted into energy, in order to adapt to the development industry. But in the course of the boiler will emit harmful substances, although it will increase the efficiency of economic and industrial development in a way, but also bring a certain degree of damage to the environment, severe cases can endanger human safety. Current coal resources and consumption of oil resources gradually increased, resulting in dust emissions and sulfuric acid type gas also increases. So our national government to protect the environment but also introduced the corresponding countermeasures, continuous improvement boiler flue gas dust removal and desulfurization process design engineering methods to improve its environmental efficiency. Flue Gas Desulfurization relevant principles of the boiler 2 into the operating principle of this embodiment 2.1 magnesia mainly refers to the use of a slurry containing MgO as a desulfurizing agent in the wash, MgO is converted to magnesium sulfite (MgSO3) and magnesium sulfate (MgSO4), the sulfur is then removed from the solution. This approach boiler dust desulfurization more mature and has been widely used in Japan and Taiwan and other regions in mainland China also has many factories, dust removal and desulphurization work in this way. Moreover, this method of dust removal and desulfurization efficiency above 90%, help protect the environment, improve the current air quality. Also in the case where the like, the amount of magnesium oxide with calcium carbonate Desulfurization only two fifths, this method shows a high utilization of raw materials, and the effect is more obvious. Currently stored amount of magnesium oxide in our country up to 80 billion tons, ranking first in the world in mining technology is also more skilled, and therefore has a considerable edge for our country. 2.2 works swirl plate absorber tower for flue gas desulphurization dust from the boiler is first enters the venturi tube, for spraying a primary dust desulfurization treatment, and then a flow rate of 15 ~ 22m / s is tangentially into the swirl plate column cylinder, firstly by the action of centrifugal force, thrown large particles in the flue gas to the tower wall, and a top-down flow of the absorbing liquid trap. This method enables the boiler flue dust separated from the gas, and to achieve the object of dust removal and desulfurization. 3 boiler flue gas dedusting flue gas desulfurization process design inside the boiler through the heat exchanger after the dust removal device into efficient desulfurization device or directly into efficient desulfurization and dust removal device, and then use the exhaust chimney draft fan. In the dust removing device which will produce gray water tank into the lime, a process using sodium lye bath kinds sodium lye, then became lime mud. If there is still the use of multi-level gray water and sludge pump liquid precipitation treatment, after diluting the high water level of the pool can be completed. Therefore, in the boiler flue gas dust removal and desulfurization process engineering design process to rational design exhaust system, flue gas purification systems, precipitation systems, inspection systems, power systems, and infrastructure-related aspects. And actively improve the quality and level design to ensure that the results of the boiler flue gas dust removal and desulfurization national environmental standards in line with the relevant departments to develop. In the process design process should also consider the cost of construction of the whole project, detailed estimates of its economic benefits and social benefits. In the course of implementation should strengthen supervision and management, to improve the quality of the environment and efforts. 4 Conclusion With the improvement of scientific and technological level of China's industrial development speed greatly accelerated. But in the process of industrial development often will use some of the energy resources, such as coal resources, oil resources and other aspects of chemical materials, use of these resources in the process will produce some waste is not conducive to environmental sustainability. Therefore, the relevant enterprises and departments should actively improve the quality of the boiler flue gas dust removal and desulfurization, improve the rationality of engineering process design, lay the foundation for improving the economic and social benefits. This requires the joint efforts of government departments and enterprises, the only way our country's socialist market economy to be able to achieve sustainable development goals, to be able to improve the economic benefits of the greatest degree.
