best oil fired steam boiler price
"Coal to gas", "coal to electricity" is the trend in recent years of China's reform boilers, all regions are gradually improving. But because some areas coal to gas, coal to electricity-related project has not been completed, the pipeline can not be normal delivery of natural gas and electricity, but there can not ban the use of burning coal for heating, resulting in some of the people cold.
Under Thus, this year, Hebei Province, will carry out the inspection work cleaning heating dragnet, scheduled for November 1 to 10, requires each village and household dragnet inspection, the gas supply, power supply is not guaranteed to get the premise not allowed to first dismantle heating stoves.
Inspection team is more than 2,000 people drawn from the province's environmental protection system, divided into 120 large groups, each group of sub-1-2 large counties (cities, districts), take the main city limits off-site inspection, cross-check each other, such as thorough investigation way, a comprehensive understanding of coal to gas, coal to electricity and clean coal work on behalf of the double security for the situation.
Wherein, the village 500 (cell) is not less than 20% of households checks; 500 villages and above (cell) checks no less than 10% of households. The main inspection five aspects, including: gas supply, power supply security, security for the clean coal and distribution, development of contingency plans, etc. under extremely adverse weather conditions. In gas supply, power supply is not guaranteed under the premise, the focus in advance to see if the removal of heating stoves situation.
Environmental Protection Department official said earlier this year in northern clean heating to proceed from reality, insist on the need for constant, the gas will change to ensure that clean heating and warm winter are guaranteed.
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.
After the gas-steam circulation pump approach failed for some time to use gas steam oven, it will produce a precipitate. At this point, we need to clean heat transfer oil furnace, but before cleaning, we need to know what kind of sediment, and then cleaned the right way, if the heat transfer oil, grease appears very easy to make the wall thermal resistance increases, will increase the production of energy, gas steam liquidity will deteriorate, production will be reduced, the operating cycle will shorten the life of the device will be. Shorten, which in turn affect production. Some of the more common gas best fired steam boiler price deposits are: sulfate, carbonate, silicon and iron. Acid sulfate does not bubbling, since relatively hard sulfates, carbonates decompose at high temperatures, the bicarbonate will dissolve, but the release of carbon dioxide will form an insoluble carbonate salt. When the temperature reaches 300 ~ 400 ℃, hot oil furnace thermally cracking occurs. It will produce carbon deposits on the inner wall and an inner wall, it affects the heat transfer efficiency. Easy to produce oil furnace heat transfer in high temperature environments. Thermal cracking, thermal polycondensation, and its kinematic viscosity increases, the fluidity deteriorates internal oxidation of the oil pipeline, oil conductive accelerated failure, the machine will be damaged, endanger human will be high. Steam oven gas processing cycle pump failure: (1) When the current is below the normal circulating pump, the circulating pump efficiency is lowered, the flow rate is reduced, the fouling of the heating pipe may be blocked, it should be cleaned. (2) circulating pump pressure constant, the current increases, flow decreases. Bad heat transfer fluid, the viscosity increased, should be replaced or regenerated. If the system does not remove water or aqueous decomposition newly heated conductive liquid should be immediately opened exhaust valve to the exhaust gas. (3) circulating pump current is reduced, the pump outlet pressure back to zero, indicating that the pump is not idle. It may be vaporized oil, gas and steam oven measures to find the cause vaporization; if the filter is clogged, the circulation pump should be evacuated and cleaned immediately opens the bypass filter; if the heating fluid contained in the new water or heated water, the system does not exclude the decomposition gas, the exhaust valves should be opened immediately exhausted.
