Details can be found! Works (in Pulverized example) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (excluding the DC furnace), into the separated saturated steam superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 1, the working principle (as an example in pulverized coal fired boilers) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (except for the DC furnace ), the separated saturated steam enters the superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 2. Pulverized coal boiler operation, the position of the center of the flame will affect evaporation. Generally, low center of the flame will lead to greater evaporation, and the high center of the flame will lead to slow evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Typically, superheated steam, in particular the reheat steam temperature in the lower center of the flame, and vice versa. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined.
In response to the call of the State Environmental Protection Department, to further improve air quality, enhance people's happiness blue sky, located in Leshan City, Sichuan Province of the energy restructuring and clean coal-fired boiler as the primary task of air pollution control, to promote the elimination of coal-fired boilers remediation work. According to statistics, from January to October this year, Leshan City, the main urban air quality index improved 11.86 percent year on year, a figure that ranked third in the province; a few good days of 251 days, an increase of 29 days, compliance rate of 82.57%; PM2.5 average concentration of 44.5 micrograms / cubic meter, an improvement of 14.09%; PM10 average concentration of 69.0 micrograms / cubic meter, an improvement of 5.74%. Improve these figures can not be separated Leshan Municipal People's Government's strong support and initiatives. Leshan municipal government adhere to precise planning, but also a public green, clean living environment.
A careful planning. Since 2017, vigorously promote energy restructuring and transformation of coal-fired boilers, in-depth investigation status of the city's coal-fired boilers, having accurate number of the city's coal-fired boilers, steam tonnage and treatment facilities, the establishment of coal-fired boilers ledger. To promote the implementation of the "coal to electricity", "coal to gas" projects the city's key industries, coal-fired boilers to transform, adjust the expansion of high-pollution fuel combustion zone ban.
Second, the fine classification. Classification of coal-fired boilers to carry out renovation work, from the source strict control of new coal-fired boiler, new and expansion projects to encourage the use of electricity, natural gas and other clean energy; with the implementation of small coal-fired boilers eliminated, medium and large transformation. The city 10 steam tons / hour or less and a total of 717 small coal-fired boiler units are all clear, a total of 1030 tons of steam. Medium-sized coal-fired boiler clean energy transformation or transformation in accordance with the deadline for ultra-low emission "should gas is gas, should the electric power" principle, Taiwan is currently the city's 44 large and medium sized coal-fired boiler clean energy transformation has been completed and ultra-low emissions transformation.
Third, the precise advance. Strengthening full control of behind schedule inspectors to speed up reform. Strengthen financial subsidies, to boost the progress of work, more than 7 million arrange special funds for the transformation of the atmosphere and medium-sized coal-fired boiler subsidy, cities, counties (cities, districts) to finance 20 steam tons / hour and clean energy alternative to coal-fired boilers the implementation of special subsidies.
Steam boiler pressure gauge should pay attention to matters 1. The rated steam pressure less than 2.45MPa 4000kg steam boilers, pressure gauge accuracy of not less than 2.5; equal to the rated boiler steam pressure 2.45MPa, the pressure shall not be less than 1.5. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Dial gauge diameter of not less than 100 mm, to ensure that the operator can clearly see the surface pressure indication. 2. On the dial gauge steam boiler should draw a red line to indicate the maximum allowable working pressure. 3. The steam boiler pressure gauge should be installed in place to facilitate the observation and purged, and should prevent high temperature, vibration and icing. 4. The steam boiler pressure gauge should be checked at least once every six months, to be sealed lead-sealed after calibration. 5. The steam boiler gauge connection tube not leak water and steam, otherwise it will reduce the pressure instruction value. 6. A steam boiler pressure gauge measuring range should be compatible with the operating pressure of the device under test, the working pressure is generally 1.53 times, preferably 2 times the working pressure. Steam boiler no pressure gauge, pressure gauge or pressure gauge damage does not meet the requirements. When the steam boiler pressure gauge of the following circumstances, should stop using: 1. The surface of the glass or the dial pins; Lead seal, lead seal is broken or exceeds the calibration period; when no pressure gauge pointer position is limited to the limit staple nail can not be restored, and the rank unlimited gauge pointer movement from zero data is out of range pressure layer. Poor; leak or pointer jitter in the meter; other defects affect the accuracy of the pressure gauge. The use of the accumulator: the accumulator for a hydraulic system of the machine intermittently. It may be a low speed motion or intermittent motion of the actuator, the oil reservoir of the hydraulic pump, when rapid movement of the actuator requires a large flow rate, as an auxiliary energy supply to the system together with the hydraulic pump, enabling the pump and the entire hydraulic system miniaturization, to achieve energy saving. Hydraulic shock absorber valve and the opening and closing of rapid mutation load, the system generates a pressure shock, loved one causes vibration and noise and even damage the machine. The accumulator can relax and absorb the impact pressure of the liquid. Accumulators absorb and reduce the pressure pulsation flow pulsation and various hydraulic pumps, thus reducing noise and vibration system. The function of the gas spring having a damper, the vibration can be used to walk between the car body and the wheel and other mechanical absorption. The accumulator may be balance gravity vertical actuator (hydraulic cylinder) and the potential energy absorbing load drop into hydraulic energy storage, while producing speed resistance. When the rising vertical actuator, the accumulator absorbs energy of the original release, and together with the oil pump to the hydraulic cylinders, so as to achieve balance and energy.Free Chat
