Boiler multiple protection: (1) the integration of boiler water level to protect water level and boiler design, the appearance of more compact appearance, accurately show the actual water level in the boiler body function. Coupled with dual independent electronic water level control system to achieve ultra-low water level in the boiler, low water level automatic adjustment function, the normal water level, high water level, ensure that the boiler in a variety of unforeseen circumstances foolproof, secure home. (2) steam pressure protection ☆ pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switch, other control lines or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; the pressure controller may be single or double fire burning fire the actual operating pressure regulator. ☆ safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.
Recently, Chuzhou City, Anhui Province issued a "Chuzhou Municipal People's Government on the issuance of Chuzhou City to win the Battle of the sky three-year action plan to implement the program," which raised more for coal-fired governance requirements, as follows.
First, the continued implementation of the total coal consumption control. As of 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's coal consumption to complete the tasks assigned by the provincial government; a new coal project implementation reduction of coal instead.
Second, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry energy characteristics, and actively promote the residential electricity, industrial production, building heating heating, transportation, production of five major areas of agricultural implement "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for.
Third, carry out comprehensive improvement of the boiler. Increase efforts to eliminate small coal-fired boilers, to consolidate the results of coal-fired boilers eliminated. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour more coal-fired boilers (excluding boiler coal-fired plants) all meet the special emission limit requirements; 65 tons of steam per hour and above all coal-fired boilers and energy-efficient ultra-low emissions to complete the transformation. Low-nitrogen gas boiler substantially complete transformation; urban built-up area of ultra-low emission biomass boilers implement reform.
Fourth, increase the technological transformation efforts cogeneration units to speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network coverage and bulk coal fired boilers within range. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume.
Fifth, strengthen the bulk coal governance. Full implementation of the "Interim Measures for commercial coal quality management" and coal-fired boiler technology standard, good bulk coal use Survey, the development of bulk coal governance implementation. Expand the scope of urban high-pollution fuel combustion zone ban, and gradually extended to the outskirts of the urban area. Combustion zone ban prohibiting the use of high-polluting coal for fuel, the progressive realization of no coal rank. Daly promote quality and new coal stoves, improving combustion efficiency.
Gas-fired steam boilers can be cleaned during cleaning using efficient and environmentally friendly non-corrosive detergents. This will cause the tube to expose the primary color of the metal and reduce the impact of dirt and bio-algal sludge. After ignition of gas-fired steam boiler, attention should be paid to observing the furnace temperature and the temperature of the main steam. With the increase of main steam pressure, the flue gas temperature of boiler is obviously increased after ignition. If the temperature does not rise, you should go to the scene immediately to inspect the oil gun fire. The scale thermal conductivity of a gas-fired steam boiler is only 1/10 of that of steel. This hinders heat transfer when it scales on a heated surface. In order to keep the boiler in use The output shall increase the temperature on the combustion side. The increase of outlet temperature of gas-fired steam boiler increases the loss of gas-fired steam boiler, and the scale on the water wall of equipment will effectively reduce the heat transfer effect, which may lead to the increase of the temperature of water wall and the burst of water wall. When a gas-fired steam boiler is in operation, a series of chemical and physical reactions will occur in the furnace. In use, it will effectively form a hard and dense scale on the heated surface, which will directly lead to its heat exchange. The reduced efficiency and corrosion due to scale will reduce the heat absorption of gas-fired boilers.
10 tons WNS-type gas heating boiler price is how much money? District, urban heating First, there are two ways of heating coal-fired hot water heating, and second boiler heating fuel gas, fuel oil and gas boiler heating is gradually replacing coal-fired boilers to be the main way of heating the moment, (the main reason can refer to gas-fired boiler and the difference between coal-fired boiler).[email protected]
