Mechanical cleaning using flat shovel, wire brushes, and motorized milling tube will remove scale, this method is relatively simple, simple structure used for small boilers made in canadas. However, mechanical cleaning is labor intensive, ineffective cleaning, boiler easily damaged, should pay more attention in the descaling operation, and this method should not be used much.
Recently, we learned, Zhangbei County, Hebei Province to speed up the transformation of low-nitrogen combustion, gas-fired, Zhangbei County Environmental Protection Agency issued the "Notice on nitrogen oxide gas boilers made in canada governance", the transformation of the way around the gas boiler, the transformation of technology formalities to conduct a comprehensive explanation of propaganda, mobilization of Zhangbei above a certain size gas boiler units to actively participate in low-nitrogen transformation.
In order to ensure the smooth progress of work, the EPA developed a grasp of leadership, and a series of regular briefings on the system, arrange for the transformation of real-time tracking progress, personally led by the leaders in charge of the transformation of the construction-site supervision, to solve various problems during installation accelerate the transformation progress of the project. To date, more than 10 tons of steam Zhangbei natural gas boilers have been completed the transformation and detection of nitrogen oxide emissions, emission concentration all the stabilizing reached 30mg / m³ or less, over-done.
To protect the subsequent reconstruction work in depth, Zhangbei County township organization, the relevant units of the county with a comprehensive Mo Pai, gas-fired, gas-fired boilers for each specific model boiler unit, whether used and other basic information has been verified, the establishment improve the work ledger; to ensure that the base number is accurate, targeted work, Zhangbei arrange strengthen docking with the gas company, promptly verify the perfect new gas boiler archives, ensure the follow-up task of transformation clear, exhaustive renovation project. At the same time, combined with the actual development of the Zhangbei gas boiler compliance programs to lay a solid foundation for the comprehensive promotion of this work next year.
The outlet temperature of the hot water boilers made in canada should be lower than the corresponding saturation temperature at the operating pressure (ie, the vaporization temperature of the boiler water) below 20 °C.
Heating boilers made in canada water wall installation What is the connection between the process and operation? Heating boiler water wall installation What is the connection between the process and operation? Since the water wall is located inside the furnace, fully understand the structure, and can know combustion furnace. At run time by measuring the wall temperature, the temperature of the header can be known indirectly working fluid parameters during inspection, we can find anomalies caused by internal squib early. By comparison of the dilation parameter, since early detection of coal boiler reasons, resulting in combustion of coke and the like is not generated properly. For operations personnel understand the structure helps to analyze the operating status of the boiler.
