Recently, Xuzhou City ushered in the good weather blue sky, sweetness and light, a set of numbers from the Xuzhou municipal environmental protection department made us confident to bring back the blue sky. According to the latest air quality in the province informed that this year, two good days in Xuzhou City 73 days, an increase over last year eight days; PM2.5 concentration of 78μg / m³, the concentration of upward momentum have been effectively curbed. The atmosphere improving governance has achieved victory.
Since April this year, Xuzhou municipal government set up the city's Operations Command prevention tackling air pollution, and the establishment of 16 specialized working groups in accordance with the classification of remediation tasks, the relevant departments to deploy officers to concentrate on work, concentrate on promoting the prevention and control of air pollution crucial action. At the same time, Xuzhou developed and issued in the history of the most aggressive, the most comprehensive measure of the "Xuzhou City in 2018 tackling air pollution control program," the task of governance engineering, project oriented, technology node.
First, action aimed at the city's 13,654 "messy dirty" business, and sort of closure to ban or stop crime measures. "Coal-burning pollution" key problem is the political commissar of the governance of Xuzhou City, after the operation began, to more than 10 tons of steam coal-fired boilers implementation of classification regulation, the city's 18 coal-fired thermal power companies implement flue gas treatment project off white, investigate and shut down downtown bulk coal processing operations point 171, for 22 coal-fired power companies and the city's 11 coal production (including coal washing) enterprises in high frequency sampling.
Furniture, printing and dyeing, filling stations and other industries, focusing on pollution VOCs special inspection work, check the company focused on source control, process management, end of treatment, the treatment facilities to ensure the normal operation of equipment, environmental protection do not have the processing power of enterprise firm shall be eliminated by shutting down.
Gas introduced a small hot water boiler heating surface area calculation, means a small boiler, soft drinks dual small boilers (Rated evaporation does not exceed 0.5 t / h, rated steam pressure not more than 0.04 MPa boiler); 2, a small hot water boiler (Rated not more than 0.1 MPa water pressure water boiler, the pressurized hot water boiler); 3, small steam boiler (not tolerating more than 50 liters of water and steam boilers rated steam pressure of not more than 0.7 MPa); 4, aluminum small pressure boiler (bulk manufacturing aluminum material selection, rated outlet steam pressure not more than 0.04 MPa and not more than 0.2 rated evaporation t / h boiler).
Operation points premix condensing boiler heating surface area calculation which, when using condensing boiler, because it takes a special principle advantage of the water cycle, etc. which have some of the heat exchange so as to achieve the desired purpose. Although one condensing boiler price is not too high, and is very simple in operation, and has a good safety performance and so on, but during the operation, the following points need to pay attention to several aspects. First, to do preparatory work before the long-term use is not running or new premix condensing boiler, before starting again with water to clean inside the system, it is extremely important for the preparation of a condensing boiler is, for the next the operation will have a role of great help. And condensing boiler manufacturer reminder should be done in the right order at the time of the official launch of, for example, to open the first circulating pump can ignite. Second, to control the operation of all the details of the process of condensing boilers run them to be able to make it work better, should be kept inside the boiler pressure always is in a stable state, and to control the temperature inside the well, so feel free to do monitoring and surveillance found that there should be any changes to certain adjustments. And condensing boiler manufacturers stressed the need to always put the pipe network in the gas discharged to go, so you can prevent vaporization of good, but also regularly carry out sewage work and to be a reasonable allocation of water inside. Third, to control the pressure in the boiler if the use of the process premix cast aluminum condensing boiler suddenly found liter high pressure inside the boiler, you should immediately identify the reasons, usually because the water temperature is too high gas of caused, so it should be appropriate to reduce the water temperature to solve this problem. There is probably because it did not deal with the dirt is clean and lead to clogging and should therefore be timely to do clean-up work in this area. But if you find a sudden drop in pressure between the condensing boiler, then it should be timely to add water to the boiler, because this is mainly due to lack of water caused. These are the aspects of the operation points premix condensing boiler included, in addition, it should give a rather regular boiler blowdown work, this can be good to avoid accumulation of dirt on the inside and cause clogging phenomenon. And in the process of condensing boiler running, it must control the water and return water temperature difference, the temperature should be controlled at less than 30 degrees, otherwise there will be some security issues.
Steam boiler is heated with thermal water (working fluid) to produce steam equipment. It consists of boiler and furnace two parts: the pot is acceptable heat boiler and the heat to the heating surface of the working fluid system; furnace is a boiler to heat the fuel chemical energy into space and flue gas flow channel.Learn More

BTU - British Thermal Units. Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour.
