chain grate wood pellet biomass fired steam boiler
4 large superior protection systems protect the water chain grate wood pellet biomass fired steam boiler steam boiler is provided with two pumps, run and standby. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Boiler plate with one or two level timing, should always be compared with each other, find instruction inconsistent, it must be corrected immediately. Each class should rinse water level gauge to determine its true level. And also has balanced water pipe poles can accurately capture level signal or alarm to the pump control. 1, a pressure protection when the boiler pressure exceeds the vapor pressure protection rating, it is necessary to chain protection: is shutdown, the system stops the combustion; nozzle can be replaced, a single stage or two stage combustion, the amount of oil can be adjusted. , thereby reducing the pressure to ensure the safe operation of the boiler. As water pressure protection with protective oil (gas) steam boilers, the use of multiple protection: (1) the pressure controller typically uses two pressure control pressure signal into an electric signal electromechanical conversion device, which is a function of the high and low pressure signals to electrical switches, and the automatic control circuit or an external interlock protection. Normal pressure controller and make electrical contact pressure gauge vapor pressure and overpressure alarm off burner limit is reached, the pressure controller adjusts single or double fire burning fire based on the actual pressure. For large burner, the fuel can be adjusted according to the amount of pressure, the pressure is always maintained in a stable operating state. (2) is the last line of defense to protect the safety valve of the boiler. When the boiler pressure exceeds the limit, according to the set pressure relief valve design, releasing exhaust pressure, in order to ensure the normal operation of the boiler. 2. Temperature protection is an important part of the process of the safe operation of the boiler, especially for steam boiler temperature regulation and protection. While achieving regulation and protection function of the hot water boiler superheater. Conventional boiler temperature protection means is a bimetallic temperature controller 3. Flameout protection against furnace explosion. Oil (gas) boiler must be equipped with flame protection device, and its function is combustion monitoring furnace (including an ignition when the ignition failure or extinguish combustion, typically re-ignited within five seconds, runs in one second, closed oil ( gas) solenoid valve, is opened concurrent silent alarm signal, the blower continues to operate at this time. after the furnace was purged of combustible residual gas, after purging two thirty seconds, the fan and various auxiliary power cut off, stopping the boiler operation.) by a flame monitoring device and control components. Flame monitor display function is to signal the presence of a flame or an interrupt from the control device. Its main purpose is a photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an ultraviolet or infrared type photoelectric conversion element, its working principle is converted to the corresponding light radiation intensity of the high current and low current. And a linear output state, the induced current is sometimes weak, and thus affect the controller amplification. 4. The self-locking power failure protection in case of sudden power failure, the boiler operation immediately closed self-locking, if the current power is restored, start at any time, must be reset to unlock in order to re-start the ignition. Imported monochrome color touch screen control system, fully automated operation. Having automatic water supply, water, over-temperature, over-voltage, automatic power failure alarm, leakage protection security systems.
Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boiler treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.
Biomass Fuel for process horizontal Steam Boilers
Using Biomass fuel for Process horizontal Steam Boilers Technical Report shows if the moisture content is too low for a given boiler design, combustion temperatures will increase and potentially cause problems with both flue emissions and ash-melting behaviour. Wood ash typically melts only above 1300 C, but other herbaceous fuels have ash-melting temperatures of ~ 1100 C. At excessive combustion temperatures, ash particles will condense on boiler tubes, heat exchangers and other boiler components and lead to corrosion or other irreparable damage to boiler parts.
Boiler structure and function of which types of the more popular types of biomass boilers is a boiler to biomass energy as a boiler fuel called biomass boilers, chain grate wood pellet biomass fired steam boilers into biomass, biomass hot water boiler, biomass stove , biomass gas steam boiler, biomass boiler vertical, horizontal biomass boilers. Classification of biomass boilers: Horizontal biomass boilers, biomass boilers vertical. Biomass Gas Gas steam boiler, biomass steam boiler, biomass hot water boiler, steam biomass gas stove. Unitary structure biomass boilers boiler consists of two parts, safety and auxiliary equipment dosing device. 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. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Boiler drum main functions: The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, fresh air ventilator tank Axial fan centrifugal fan avoid pot containing a high concentration of salt and impurities water with the steam entering the superheater and a steam turbine. Internal boiler drum apparatus: comprising a steam separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also for further separation louvers, steel wire or plate or the like are vapor . The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities.
