gas fired 10 ton steam boiler
The working principle of fired 10 ton steam boiler steam boiler with boiling water almost equivalent to pot kettle, oven stove equivalent. Boilers and boiler furnaces is divided into two parts, the pot is filled with water to a metal container, partially combusted fuel furnace, the heat absorption of the water inside the pot furnace fuel combustion converted to steam. Popular terms, the steam boiler is to absorb combustion heat of the fuel into the water some parameters (such as pressure, temperature, etc.) of the steam device. For example, everyone knows to pulverized coal, for example. 1. The operation principle (an example in pulverized coal fired boilers) in heat pulverized coal combustion furnace, radiative heat transfer is first absorbed by the water wall, the Wall Boiling water, a large amount of steam into the drum for steam separator (DC furnace excluded), the separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2. Pulverized work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small; also affects the position of the center of the flame superheated steam or reheat steam temperature, generally lower the center of the flame in particular superheated steam reheat steam temperature to be low, otherwise higher. 3. The arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion.
Pressure boiler furnace designed with the characteristics of the fuel pressure boiler furnace designed with the two main parts of the boiler body is characteristic of the furnace and the fuel pressure drum. Furnace, also called a combustion chamber, a fuel combustion space. The solid fuel on the grate furnace called stratified combustion furnace, also called fire bed furnace, and a liquid, gaseous or solid powdered fuel is injected into the combustion chamber in a combustion furnace, combustion chamber furnace referred to, also known as for the furnace fire chamber, a liquid, a gas or a pulverized solid fuel injected into the combustion chamber of the furnace, also known as combustion furnace; coal particles and air lift to a boiling state combustion furnace for combustion of low-grade fuel is called boiling furnace, also known as fluidized bed furnace; high-speed rotation of the coal particles by a gas flow and strongly cylindrical combustion furnace known as a cyclone furnace. Atmospheric overall configuration of a boiler furnace body includes two parts and auxiliary equipment. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler combustion of the original fuel should as much as possible. Different characteristics of fuel economy will reduce boiler operation and reliability. It is a natural circulation boiler drum and multiple forced circulation boiler, economizer receiving water circulation circuit connected to the saturated steam supplied to the superheater of the cylindrical container. Boiler drum is made of high quality steel plate, it is one of the heaviest components of the boiler.
10 t 10 t introduce gas boiler gas boiler fired 10 ton steam boiler dedicated configuration computer controller, all Chinese, a large screen, backlit LCD display strong, rich display, operating status of the controller and the collected pressure, water and other states may be accurately visually displayed. Complete control functions, with intelligent boiler water level control, steam pressure control, low-limit water level alarm and interlock protection, high water level alarm, ultra-high pressure steam alarm and interlock protection, automatic control functions. Very convenient to use, may be provided continuously, the timing of the two states, the timing can be divided into four time periods, the boiler regular boot, time off, without full fireman, usually only have to press the start key turned on, press the stop button to stop very easy. Features: imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) to automatically adjust the proportion of oil wind, good atomization, combustion, low NOX, energy saving . Under normal circumstances, when the boiler steam pressure reaches the set value, the burner combustion is automatically stopped, when the steam pressure is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically. Advantages 1,10 tons of gas steam boiler furnace design and manufacture Three-pass boiler, wet back, eccentric furnace, asymmetric structures, waveform furnace, so that the flame produced a strong disturbance, and increased radiation heating surface, increased strength heat transfer coefficient, and can effectively prevent metal thermal expansion and contraction resulting in reduced life of the device. 2, the whole high degree of automation, security improved. Run fully automated process, with automatic replenishment, water shortage, overpressure, automatic power off and alarm, leakage protection and other security systems. 3, the whole body as glass wool type insulation, light weight, good thermal insulation effect, less heat loss; protection system: (1) protect the boiler water level indicator and integrated design of the boiler, the appearance of a more compact appearance, function accurately display the boiler The actual body of water. 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.
Further promote air pollution control work, the Office of the ecological environment of Shanxi publicly stated: Shanxi Province will strictly control the total coal consumption; reduce the proportion of coal in primary energy consumption; Where ban on coal sales area of coal and coal products, both will be subject to heavy penalties.
Shanxi Province has also developed regulations, Municipal People's Government in accordance with the requirements to improve the quality of atmospheric environment, urban built-up area designated as the ban on coal zone, and gradually extended; counties (cities, districts) People's Government may delineate the scope of ban on coal zone according to the actual situation but life should be a primary consideration the needs of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.
At the same time, governments at all levels in Shanxi province will also strengthen civil bulk coal management, prohibit the sale, does not meet the civil standard of quality coal for coal; prohibition of lignite, coal washing, slime and other low-quality, low-grade coal as a civilian coal use. Various localities will accelerate the cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion of distributed coal-fired heating boilers; central heating pipe network coverage prior to the completion of use of scattered coal-fired heating boilers have been built and can not meet emissions standards coal-fired heating boilers, demolition will be completed within the deadline.
For violation of the provisions, sales do not meet the quality standards of civilian coal for coal, or the ban on coal sales coal region and its products, the people's government above the county level by the market supervision and management department confiscated of raw materials, products and illegal income, impose a fine of three times the value of the amount more than doubled.
