vertical biomass pellet steam boiler

4 large superior protection systems protect the water vertical biomass pellet 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.

75 ton biomass power plant boiler in Malaysia

150 hp horizontal gas steam boiler for oil refinery

Fluidized bed boilers are the most recent type of boiler developed for solid fuel combustion. And 35 ton coal fired CFB vertical biomass pellet steam boiler is hot sales in industrial market. As a top steam boiler manufacturer in China, ZG Boiler keeps on technology innovation and development. The primary driving force for development of fluidized bed combustion is reduced SO2 and NOx emissions from coal combustion. As the technology developed, it became apparent that the process could efficiently burn biomass and other low-grade fuels that are difficult or impractical to burn with conventional methods.

Inner Mongolia Autonomous Region for the winter heating long-term, large coal consumption of the actual situation, "strictly control coal pollution" as a top priority to improve air quality.

According to statistics, in 2018, Inner Mongolia fully complete the remaining 10 127 tons of steam / hour and small coal-fired boilers out of the task-level urban built-up areas; Hohhot, Baotou, Wuhai more polluting coal and other built-up urban area start 35 steam tons / hour and the phase-out of coal-fired boilers.

Inner Mongolia this year also completed shantytowns 142,000, an increase of central heating an area of ​​11.36 million square meters, the "coal to gas," "coal to electricity" pilot project, the region cut loose coal burning 636,300 tons.

In addition, in order to fight the "Battle of the sky" tough fight, Inner Mongolia this year has introduced the "Atmospheric Pollution Prevention Act," "Blue Sky Battle win three-year action plan to implement the program" and other local laws and regulations.

From January 2018 to November, Inner Mongolia Autonomous Region average PM2.5 concentration of 30 micrograms / cubic meter, down 6.3%, the ratio of the number of good days to reach 83%.
