Which fuel hot water boiler For now, the gap between domestic hot water boiler fuel suppliers, power analysis, and each has its own strengths oil hot water boilers case. I do not know if you judge oil hot water boiler is really a problem of what professional standards. Now normally want to choose the right people for the fuel hot water boiler units, listed some of the following criteria need to know: First, hot water boiler fuel consumption indicators Second, oil hot water boiler steam out time three or oil hot water boiler the provision power four, on the style of some of the standard fuel hot water boiler, hot water boiler fuel is enough to get absolutely inappropriate common, most also need to think twice inappropriate, from some of these criteria, you should see 1 oil-fired hot water boiler efficiency is really a problem, of course, hot water boiler fuel election day for all of us to find the most units, the price of oil hot water boiler is the most important.
How fuel gas 4 ton water steam boiler manufacturers water treatment found that fuel gas steam boiler water, rinse water table by "waters" to determine mild or severe water shortage. "Waters" steps are as follows: Table 1 Open water drain cocks; Table 2 off water vapor cock; Table 3 closed water drainage cocks. At this point, if the water level in the water table appears, the boiler is a slight lack of water, or is the severe water shortage. 1, slightly water boiler, be the first open water gauge steam cocks, restore the normal operation of the water table and reduce the fuel and air supply, reduced burning, slow to Boiler Feed, and quickly identify the cause of the boiler water shortage. When the boiler water level to be gradually restored to safe water level above the minimum, and then increase the fuel and air, to restore normal combustion boiler. 2, severe water boiler, not to Boiler Feed, there may have been because the boiler Griddle, boiler or red-hot metal may be in a superheated state, upon addition of water will be serious danger. Emergency shutdown procedures should be required to immediately boiler severe water shortages.
Note that, these condensing boiler cleaning errors occur frequently in many condensing boilers manufacture, transport and installation in a variety of situations will occur, so that the pipe wall boilers accumulate a large amount of dirt or other impurities in the oxide, resulting in the initial boiler run directly heating surface corrosion damage. To this end, boiler manufacturing companies will configure a set of operating instructions for each condensing boilers, including cleaning this one. Then the process consumers condensing boiler cleaning in which errors can strayed, how to avoid it? A chemical cleaning process does not detect the chemical analysis is a very rigorous chemical cleaning process. But if chemical cleaning is not complete, some dirt is not completely clean; and if the cleaning time is too long, there will be over-wash phenomenon; good cleaning effect, a secondary cleaning will waste of raw materials, and waste time. Which will increase the erosion had washed condensing boiler, condensing boilers metal pressure caused by a reduced ability of the normal operation of condensing boilers after impact. Improvements are: chemical analysis must be prepared to detect chemical cleaning processes, test once every tens of minutes acidity, total iron ion concentration, PH value. When two close data laboratory analysis, chemical cleaning end point is reached, and be discharged after reaching the neutral acid. Second, chemical cleaning is not performed after completion of the passivation process is the process of passivating the clean surface of the condensing boiler deactivators re reaction. Since the control point passivated more stringent requirements, if not properly controlled, the passivation will fail, and if the pickling is completed, and only a simple cleaning is finished, which makes the surface to be cleaned boiler condensate prone to two secondary rust, scale condensing boiler capacity decreases, prone to rust improvements: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled total iron ions concentration. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation. It can be learned from the above, chemical cleaning condensing boiler there are more abnormal phenomena, and that the life of the condensing boiler, safe operation, energy production had a negative impact, therefore, in order to eliminate these abnormal phenomena, sustainable development and safe use of condensing boilers environment has a very big role.
A few months ago, Shandong Provincial People's Government issued the "Opinions on Further expand domestic demand and promote development of up short board", which refers to: As of 2020, invested 11 million yuan to complete 5.4 million renovation to replace it clean, let 55 % of villages to achieve clean heating.
In the "clean warm winter Shandong Province Planning (2018-2022 years)" is mentioned, in 2020 the provincial average clean heating rate of 70%, of which more than 20 million people in the city basically clean heating full coverage. 2022, the province's clean heating rate of over 80%. Among them, more than the city and county basically clean heating full coverage, the average clean heating in rural areas reached about 75%.
Jinan, Qingdao, Yantai City 3 converts kinetic energy as a province of old and new core area, to take the lead in forming an electrical heating alternatives such as clean coal-fired heating San basic pattern. Should be in accordance with the electrical power, should be renewable energy sources of renewable energy, the principle of the dispersed phase concentration and binding, while the priority of central heating, the positive development of other energy sources for heating air.Free Chat
