cbl afbc coal fire presses boiler
Henan district heating gas cbl afbc coal fire presses boiler heating characteristics and uses of a cell or several cells share one building gas boiler room heating using the secondary heating network, an intermediate heat transfer station, the larger the size of the external heating network. Heating area up to several million square meters of high-altitude emissions fumes. 1, Henan area gas boiler heating system to the Characteristics of A, using the advantages: gas boiler Henan province invested more decentralized heating, can achieve centralized management, easy maintenance and users can achieve high-altitude emissions of pollutants. Coal to gas project, you can use direct existing heating systems and boiler room ancillary equipment, saving the initial investment. B, there is a drawback: the thermal efficiency is relatively low, and heat transfer stations outside the network heat losses and the heat medium conveyance power consumption, high emissions of pollutants, the system adjustment is not flexible, large investment outside the network, does not solve the problem of direct measurement of the heat. In the beginning of the construction of the system utilization is low. The end of central heating systems without measurement and adjustment means. Flat Rate according to heating area. Hydraulic imbalance caused by high temperature heating part of the user, when the room is overheated, the user typically using cooling method fenestration adjust the room temperature, resulting in 8% to 15% of the heat loss. Particularly in the construction of mixed use of different nature, according to the same level of heating, because no means of regulation, office buildings, schools and other heating at night and holidays, the hotel was no usual heating, waste of energy. 2, Henan gas boiler gas consumption due to heat loss outside the network is greater than the dispersion of Henan gas boiler heating, the heating temperature is higher than the average gas boiler single-family household heating Henan, Beijing heating in the gas consumption index 10-14m3 / m2. Gas consumption is mainly due to heat loss and heat transfer stations outside the network than other reasons for the high two ways, hydraulic imbalance serious nature of the use of different architectural mix caused by heating. 3, the heating system uses the ground region Henan gas boiler pollutant concentration requirements more stringent, while heating the dispersion concentration of pollutants discharged warm floor exceeded, central heating may be employed. However, there are requirements for stack height shall be determined through calculation. Rarely used in Europe and North America gas central heating boiler area, or are generally thermoelectric cooling and power generation.
First, to improve the fuel will be coal into gas in principle, more in line with the relevant environmental standards, coal as fuel for the cbl afbc coal fire presses boiler has been subject to the authorities to stop, that there is often a company will be coal-fired boilers on the boiler rehabilitation programs into gas boiler embodiment, may use natural gas or alcohol as a fuel after passing through this transformation, the raw coal to reduce all kinds of pollution caused by the fuel, thus using not only environmentally friendly but also improvement in the fuel cost. Second, improve coal-fired furnace boiler furnace to transform into a blast furnace gas fired boiler is the use of auxiliary heating furnace, and then to improve the use of gas for heating, if not exactly when or poor fuel atomization in the combustion furnace gas gathering or tail, it is very prone to catch fire or explode, then the need for means to improve the furnace blast doors, while adding automation and control ignition and flame failure protection devices to ensure safe operation of the furnace process. Third, improve the pre-attached devices did not improve during the coal-fired furnace operation requires a lot of ancillary equipment to carry out normal operations, ancillary equipment commonly used in general including the coal, Cleaner, dust collector and grate and so on, after adoption of these boiler ancillary equipment gas furnaces do not need to use so that you can save and invest more of boiler equipment. Fourth, improve environmental protection degree We all know that coal-fired furnace has been impermissible environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, after making use of the boiler gas furnace, greatly reducing soot and various soot emissions can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with the standards of environment protection and energy policy.
Coal-fired heating cbl afbc coal fire presses boilers derivative gas project analysis have been carrying out renovation work with the provinces and municipalities boiler, heating areas have gradually entered the ranks of the transformation, from coal to gas is one of a direction following Xiaobian take you to do a simple analysis. (1) Since the background transformation in coal-fired boiler during operation, high nitrogen oxide emissions of compounds, lower operating thermal efficiency, the actual effectiveness of lower bring the actual situation, the coal gas projects imperative. (2) the transformation of the type and price analysis for the transformation of coal boiler roughly divided into two macro-transformation methods for a local auxiliary boiler configuration, for example, combustion adjustment and transformation of machine type; the other is the removal of the new boiler reconstruction. Depending on the transformation of the standard, its transformation price is not the same. Auxiliary configure the amount of replacement level is to be replaced, the price naturally vary according to different standards, it is basically to analyze specific issues. (3) The reconstruction for the related art to enhance the current boiler, boiler manufacturers in their respective transformation technology or technology patents do a certain degree of improvement and upgrade, for example, condensation technology, technology, low nitrogen, which are object in order to ensure that the boiler after the transformation has substantial progress in terms of performance or configuration, bring substantial benefits to the relevant enterprises or institutions run. Of course, the timeliness of a coal-fired heating boilers gas heating boiler change not only consideration of the item price, technology, and services related to the transformation process, the transformation of the security dimension, it will be more concerned about the point, of course, the quality of a project is considered part of the standard.
In order to improve ambient air quality in the region, Linfen City, Shanxi Province with the actual situation, issued a notice "Linfen City in 2019 iron and steel, coking industry depth reduction plan". "Program" is mentioned, requiring all enterprises in the implementation of the transformation process of governance, compliance with the target, select advanced, mature, stable, and reliable control technology implementation of the transformation.
