First, the concept of "soot blowing", the long-run gas hrsg waste heat recovery boiler by group, heating surface fouling and coking occur, so that the heat transfer deterioration; backpass respect, since the long-term accumulation of combustible material, is likely to occur reburning fuel incidents, hence the need for sootblowing work heating surface in the boiler after running for some time, in order to clean the boiler heating surfaces. Second, how to complete the "soot blowing" 1, using a short sootblower lance tube furnace for heating water wall surface sootblowing. 2, with a long flue soot-blowing lance tube, a superheater heating surface sootblowing reheater, economizer, air preheater and the like. Third, the "soot blowing" effect on the safe operation of the boiler to gas boiler soot blowers can cause negative pressure boilers, steam temperature, steam pressure, load, fluctuations in the water level, but also bring to the boiler soot blowing influence of different heating surface They are not the same, to deal with these parameters in the process of strengthening the soot-blowing view. On the impact of boiler soot blowing, in the following areas: 1, soot blowers for the stability of combustion have been affected, in the soot blowing process should strengthen the monitoring of combustion. 2, at low load operation and combustion instability, can not work sootblowing; simultaneously, so that the heating surface cleaning sootblowing, increased heat absorption, thus making the exhaust gas temperature is lowered. 3, since the sootblowing furnace pressure fluctuations result, a large negative pressure should be maintained in the furnace to prevent soot blowing to take pressure.
Winter heating season is approaching, Jinan City, Shandong Province in response to the country clean, low-emission environmental requirements, increase efforts to support the promotion of winter heating clean, clean heating to further enhance the city level, issued on the issue clean winter heating engineering and operational capital subsidy Notice.
Second, the use of centralized gas boiler user, uniform implementation of preferential gas prices 1.71 yuan / cubic meter, the heating period and after the end of the third-party audit of gas consumption, gas will be the final settlement price (not exceeding Municipality department approved between the reference price) and 1.71 yuan / cubic meter price difference subsidy to the gas company, to purchase heating companies use non-city franchise gas pipeline business gas heating can be direct subsidies to heating companies.
Third, the use of electricity users centralized heating, heating period and by the end of the third-party audit by the electricity, the power company will operate the unit with the settlement price and preferential rates (level of 0.5 yuan / kwh, Valley Electric 0.25 yuan / kilowatt the difference between the time) subsidy to operate the unit.
Fourth, the use of formula household heating boiler user, purchase subsidy subsidy to the user equipment or units in accordance with Standard 2000 underwritten yuan / household. Temporarily performed using the sub-family user heating boiler gas prices during the step, performed in accordance with a first gear price urban gas prices; after the heating period, gas operation subsidies subsidies to users according to standard 1200 / household .
Fifth, the use of household electric heating type user, can also get subsidies. Subsidy ranges: The air source heat pumps, domestic electric boilers, heating cables, heating the carbon crystal plate user. According to the notification, the device according to the purchase subsidy subsidized purchase truly carbon crystal plate does not exceed 2,000 yuan / household air-source heat pump, domestic electric boilers, heating cables subsidy standard is 2000 Yuan / or household user to Advancer units. After the heating period, power to the user according to operating subsidies subsidies 1200 / standard household.
The need to boil hrsg waste heat recovery boiler by group and boiler shutdown protection measures during the reasons: the boiler, during its shutdown, if you want to take some protective measures? Why boiler boil? In addition, the boiler thermostat should be how to set the start and stop temperature? All these questions and boiler-related products this important site, so the following, to explain in detail and answer, so, so that we have a correct understanding. 1. During the boiler shutdown, if you want to take some protective measures? Boiler, during which shutdown is to take some protective measures, because if you do not, then, the internal boiler corrosion of the metal surface will produce dissolved oxygen and temperature in an oxygen effect, especially in the superheater section . So, to take some precautions to avoid this problem inside the boiler, is the rusty metal corrosion. 2. boiler thermostat start and stop temperatures, how to set? Boiler thermostat, which is an important component, so its start and stop temperature setting, is an important work, and can not be careless treatment, so the following to briefly explain. Start temperature setting thermostat: the thermostat on the power cord plugged into an electrical outlet, the digital display face panel, press the start set the "+" key or the "-" key to start temperature set up. At this time, the temperature of first table shows the thermostat, the temperature is to start the circulation pump. Thermostat temperature setting stop: it is very simple, just stop setting the "+" key or the "-" key to stop the circulating pump set temperature, the temperature of the first table shows the , it is to stop the circulation pump temperature.
Fast hrsg waste heat recovery boiler by group summarizes several reasons, you can refer to the investigation own electric heating boiler equipment, whether or not there is a case, if there is, as soon as possible to solve, not to invest more in electricity costs.
