Two kinds of electric boiler heating mode boilers typically have two electrical heating mode, one is manual heating mode, the other is the automatic heating mode. 1. Manual mode is very laborious manual mode, the heating mode is manually species to adjust the temperature of the electric boiler, the efficiency of this mode is low, 2. fully automatic mode automatic mode is to set the electric boiler a temperature range, the whole days are set into a number of time periods, so that the electric boiler will be set up in accordance with the requirements of automatic operation, two electric boilers can be said that this model not only very convenient, but also very power after setting reasonable, all users should use a pattern.
Energy is the basis for social and economic development, whether industrial production, or the ordinary life are inseparable from energy. But the current global shortage of energy in all environments, dramatically reducing the amount of storage of energy in order to achieve sustainable social and economic development must make energy saving measures. The proportion of energy consumption boiler and heating system is very large, so do the skills of boilers and heating systems control is very necessary.
The construction of boiler requires that the installation of boiler has certain requirements to the construction of boiler room, and it must accord with the relevant requirements of the state in the process of construction. 1) the boiler house must conform to the regulations of Technical Supervision and Management of Energy Saving of Boiler and Design Code of Industrial Boiler House. 2) the boiler room should be adequately lit and well ventilated, and there should be necessary anti-freezing measures. And boiler rooms should be away from schools, housing and densely populated places. 3) the position of boiler room should be as close as possible to the heating equipment, so as to reduce the head loss of hot oil circulation pump and heat loss of pipeline. 2, Heat-load furnace equipment layout requirements 1 ) the oil storage tank shall be 1 metre lower than the lowest position of the heatload furnace and the heating system in order to clean up the organic heat carriers in the boiler and system, and the oil storage tank shall be spaced not less than 5 metres from the heat carrier furnace or separated by a partition wall. An exhaust pipe shall be installed on the oil storage tank and the diameter of the exhaust pipe shall be one specification larger than that of the expansion pipe. 2) the position of the expansion tank shall be higher than that of other equipment and pipes in the system, and the bottom of the expansion tank shall be 1.5 metres above the maximum liquid level of the system. Do not install directly above any boiler to prevent an organic heat carrier from spilling over to cause a fire. 3) the oil storage tank and the discharge pipe on the expansion tank shall be connected to an outdoor safe place. Valve not to be installed on discharge pipe to protect The storage tank, expansion tank and atmosphere are connected to ensure normal pressure operation. 4) the volume of the high expansion tank should be 1.3 times greater than that of all organic heat carriers in the heat carrier furnace and the whole heating pipe network system under the working temperature due to the thermal expansion. 5) the volume of low-level storage tank should not be less than 1.2 times of the total amount of organic heat carrier in heat carrier furnace. 6) keep at least 0.5 meters of space around the hot oil circulating pump to ensure daily inspection, installation and maintenance.
Yesterday we learned that the Guangdong Province to increase pollution control efforts by the provincial people's government approval, Guangdong Province Market Supervisory Authority, the ecological environment of Guangdong Province, Guangdong Province, recently issued jointly approved by local standards "boiler air pollutant emission standards." Compared to the original standard, including contaminant particulate matter, sulfur dioxide, nitrogen oxides, etc. received strict emission limits help to further reduce the total emissions of air pollutants.
Provincial Department of environment-related offices responsible person, the current Guangdong Province "Boiler Air Pollutants Emission Standards" promulgated and implemented more than eight years, with advances in pollution control technology, emission control requirements of its apparent leniency. Meanwhile, Guangdong air pollution control task is arduous, urgent need to close strict standards, further reducing the total emissions of air pollutants.
Guangdong "boiler air emission standards" in the context of the implementation province domain for coal, the material forming the fuel oil, gas and raw fuel 65 tons of steam per hour and less steam boilers, hot water boilers of various capacities and Heat Transfer Material Heater; stoker various capacities, stoker furnace.
The new "boiler air pollutant emission standards" (DB44 / 765-2019) to adjust six major areas.
A clear the raw fuel material forming air pollutants emission limits fuel boiler;
Second, the received strict emission limits boiler air pollutants, increasing the emission limits coal boiler mercury and its compounds;
Third, the abolition of provisions different emission limits by functional area and boiler capacity;
Fourth, in particular an increase of atmospheric pollutant emission limit requirements;
Fifth, increase the fugitive emission control requirements;
Sixth, the excess air ratio conversion flue gas pollutants to the atmosphere of pollutants emission concentration of the reference oxygen content conversion, the oxygen content of the clear reference atmospheric pollutants fired boiler burning biomass.
The new standard in the province gamut execution, the execution time of the specific step-wise: new boiler effect since April 1 this year; the transformation of boilers give some time, depending on which region, from 1 July 2019 2020 or the date of July 1 implementation of the new standards.
