boiler egg noodles kiosk
Clinker grinders are provided in boiler egg noodles kiosks to grind large pieces of clinkers into small ones so that choking of the exhaust hole may be avoided, but it is observed in many thermal power plants that clinker grinders are out of service due to negligence or being considered a redundant feature. Due to this negligence large pieces of clinkers can choke the exhaust hole of the hopper and accumulation of small pieces of clinkers and water starts above it. Clinker grinders must be made operational.
SZS type fuel gas boiler egg noodles kiosk flue gas temperature is lower flue gas loss is smaller SZS type fuel boiler thermal efficiency related to many factors, one of which is the exhaust gas temperature of the boiler, based on past experience, type of fuel gas boiler SZS the lower exhaust gas temperature, exhaust loss of the smaller, the higher its thermal efficiency. But in the design to reduce exhaust gas temperature, then we must increase the tail heating surface SZS type of fuel gas-fired boiler, which requires increased investment and metal consumption. And if the exhaust gas temperature is too low, reach the dew point temperature of flue gas, the sulfur dioxide in the flue gas condenses on the wall surface of the air preheater, a low-temperature corrosion. Especially when SZS type fuel gas-fired boiler to burn more fuel sulfur content, this low-temperature corrosion can appear more intense. Low exhaust gas temperature should be determined by a technical and economic comparison, the fuel gas for the boiler type SZS large capacity, the exhaust gas temperature is generally rated at between 110 ℃ ~ 160 ℃ it.
Recently, Guangdong Province issued a "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019) (hereinafter referred to as the "standard").
A "standard" in the context of the implementation province domain for coal, oil, 65 tons of steam per hour and the material forming steam boiler burning fuel gas and raw, hot water boilers of various capacities and organic heat carrier boiler; stoker of various capacities, stoker furnace.
Second, the implementation of the emission limits of air pollutants specified in Table 1 of the boiler since July 1, 2019, since 2020 July 1 implementation of air pollutant emission limits specified in Table 2.
Third, the new boiler since April 1, 2019 (the date of the present embodiment standard) executed from air pollutants emission limits specified in Table 2.
Fourth, not the implementation of clean energy transformation of 35 tons of steam per hour and higher coal-fired boiler from January 1, 2021, implementation of the provisions of air pollutants emission limits in Table 3 in particular.
Tell your boiler egg noodles kiosk business, operating points premix condensing boiler premix condensing boiler is the new show condensing boiler, using a condensing boiler premix combustion technology, not only exhaust gas temperature is low, reduce harmful substance emissions; also allows fuel combustion, releasing more heat. Although premix condensing boilers currently on the market most of the use of intelligent control system is very simple in operation, and has a good safety performance and so on, but during the operation, the following points still need to pay attention to three aspects. First, prior to use to prepare for long-term work is not running or new premix condensing boilers, to make adequate preparations before starting work. First of all to clean up the boiler, it is extremely important for preparations for condensing boilers, for the next operation will be of great help. And fast boiler remind you that should be done in the correct order when starting the boiler, not free to adjust the order of operations. Second, pay attention to the details in the process of running premix condensing boiler, the boiler should be kept inside pressure always is in a stable state, and to control the temperature, so as to make it a better working condition; Therefore, to achieve real-time monitoring, once any abnormality occurs, immediately discovered and certain adjustments. At the same time, often also in the pipeline to discharge gas, which can well prevent the occurrence of vaporization boiler, regular work of the sewage water is also very reasonable and important. Third, control the pressure inside the boiler if the boiler pressure suddenly found inside a high rise in the premix condensing boiler process, it is necessary to pay attention to, and immediately investigate the cause. Normally this is because the water temperature is too high to cause vaporization occurs, it should be appropriate to reduce the water temperature. There is probably because there is no deal with clean dirt caused by clogging occurs, and therefore should be timely to do cleanup work. If found premix condensing boiler pressure sudden drop in between, then it should be timely to add water to the boiler, which mainly may be due to lack of water caused. These are the main points premix condensing boiler operation fast boiler for your summary. In addition, you should also give regular boiler blowdown work, this can be good to avoid the 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.
