large gas fire tube steam boiler
New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the boiler. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.
Henan difference fast boiler large fire tube steam boiler steam boiler is a steam boiler with ordinary steam production machinery and equipment, generally used gas, or coal gas as a fuel, there are an electric steam boiler. Henan fast boiler for the inspection of the steam boiler is a steam boiler gas, fuel oil, gas, and it is common conventional steam boiler with the following differences: "steam boiler supervision norms" and the forthcoming introduction in June next year the new pot rules " boiler safety technology to monitor the specifications "are clearly defined steam boiler needs to be regulated by the state. In other words, users looking to buy a steam boiler plant boiler installation and can not be used directly. Before installation To pot seized by the approval and registration required for installation, and the need for inspection on a regular basis, usually one year during the annual inspection. But there are some of the steam boiler does not require registration and annual inspection, the old rules and the new pan pot regulations stipulate a water capacity less than 30L steam boiler is not within the scope of the surveillance. Because the water capacity of 30L water capacity than at home with a water heater are also small, so there is no risk of explosion, we do not need supervision. Henan water capacity fast boiler steam boiler 26L, belongs steam boiler does not require supervision. Steam boiler explosion hazards generated is amazing. In many steam boiler explosion in the boiler room were razed to the ground, the annual explosion of a steam boiler will be the first to cause casualties and significant economic losses. Henan fast boiler steam boiler is to achieve the ultimate, the boiler body through the scientific design, water capacity is very low, only 26L, itself, there is no risk of explosion on security. The thermal efficiency of conventional steam boiler is only 80%, while the party Henan boiler thermal efficiency of fast gas steam boiler can reach more than 93%. Henan plus energy-saving system fast boiler control systems, the actual energy savings up to 30%, running down a year could save hundreds of thousands of operating costs. The Henan fast boiler steam boiler without boiler room, an area itself is small, you can put in the basement or roof, it can also be placed directly next to the device requires the use of steam. Saving the cost of laying pipe network construction costs and the boiler room, a significant reduction in the use of the initial investment.
Steam boiler pressure controller function and debugging methods fired boiler, gas-fired boiler, large fire tube steam boiler pressure controller and debugging method acting pressure controller is a pressure signal into an electric signal electromechanical conversion device, its function will be the high pressure or low levels of The electrical switching signal to the external circuit for automatic control or chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the oil / gas, and always keep the pressure stable operation. Currently electrical contacts have been rarely used. Above the boiler pressure controller typically uses steam boiler pressure controller are used two to three pressure controller. Wherein a start and stop control furnace, for controlling a large and small fire conversion, there is used an overpressure protection. Two start and stop the boiler pressure controller is generally used to control the temperature controller, pressure controller is arranged to control the two-position and fire the boiler overpressure protection. Three safety accessories on the boiler must be in accordance with the procedures set two, which is intended primarily for safety. First, you can work to prevent another when one of them fails. Second, the purpose of comparison, in particular water level gauge and a pressure controller, to ensure safety, the operator to observe only one of which is the value indicated, but also controls the display shown two values match. 3 generally require a pressure controller, operation is as follows: the first is a power adjusting; e.g. a small fire is set 0.5MPa, 0.4MPa furnace start, the adjustable screw -difference pressure controller (hysteresis) is 1, range (set value) is set to 5. The second pressure is shutdown, diffe set to minimum, range adjusted to 6 (0.6MPa). The third overpressure alarm is set at about 0.7Mpa. Note: the pressure differential must first be transferred back controller adjustment process, and then transferred range. Gas steam boiler pressure controller debugging, generally follow the principle: high pressure, is used as the overpressure protection; high pressure, as boiler start-stop control; low pressure, as a large and a small fire conversion. Specific pressure range may be adjusted according to the nominal pressure boilers and the requirements of use.
Hefei Limin Pharmaceutical Co., Ltd. Nanjing Military Region, formerly the backbone of pharmaceutical companies, the main drug is slowly swallow rather teabag, relying on advanced R & D platform to carry out contract manufacturing, OEM OEM and other business cooperation. China's environmental protection development trend began to take shape, many environmental policies have been put forward for a positive response to the national environmental policy, Limin Pharmaceutical decided to introduce a gas station large fire tube steam boilers. After an investigation of the boiler market, Limin Pharmaceutical fast boiler is strong comprehensive strength and wealth of experience working for many years in the pharmaceutical industry to attract, party fast according to the actual needs of customers for its recommendation of one of Taiwan 4 tons of steam condensate gas-fired steam boiler (WNS4-1.25-YQ).
