biomass steam boiler industrial
4 large superior protection systems protect the water biomass steam boiler industrial 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.
Biomass fired biomass steam boiler industrial combustion process
The biomass fuel is fed into the furnace screw feeder, where due to the high temperature flue gas and the role of the primary air gradually preheating, drying, fire, burning, this process a large number of volatile precipitation, burn vigorously. After the resulting erosion main heating surface temperature flue gas boiler, the boiler economizer heating surface of the tail and air preheater, and then into the dust, and finally through the chimney into the atmosphere. Not gasified fuel side to the rear of the grate movement until burnout, the last remaining small amount of ash fall behind the grate slag mouth.

Recently, Hangzhou Provincial People's Government for the quality of atmospheric environment issues issued a deadline for compliance plan, as follows.
First, the situation and challenges
Since the "Atmospheric ten" implementation of Hangzhou to build an ecological civilization as a guide to improve the quality of atmospheric environment as the goal, carry out air pollution prevention and control actions to protect the G20 summit in Hangzhou as an opportunity to promote a strong "coal-fired flue gas, industrial emissions , vehicle exhaust, dust gray gas, urban and rural exhaust "other" gas cohabitation ", strengthen regional joint prevention and control, air pollution control and achieved remarkable results, no built coal-fired thermal power, iron and steel producers no, no emission vehicles "three noes" urban atmospheric environmental quality continues to improve.
(A) Key Performance
1, ambient air quality improved significantly.
In the case of the national economy with an average annual growth of 9.1% of the "second five" major pollutants emission reduction achieved remarkable, sulfur dioxide, total nitrogen oxide emissions compared to 2010, respectively, decreased by 21.9%, 26.5%, exceeding the state-assigned the reduction targets and tasks.
2, energy and industrial structure gradually optimized.
The city's total energy consumption growth narrowed year by year, total energy consumption in 2015 was 39.48 million tons of standard coal, an average annual increase of "Twelfth Five-Year" period is only 3.4%, compared with the "Eleventh Five-Year" down 2.1 percentage points.
3, industrial pollution prevention deepened.
Promoting desulfurization and denitrification and dust removal facilities, coal-fired thermal power generating units are completed desulfurization, denitrification facilities, a total of 87 coal-fired thermal power generating units ultra-low emissions transformation.
4. The motor vehicle exhaust pollution prevention and continuous progress.
"Twelve Five" period, and comprehensively promote the yellow car out of work in 2015, the city basically eliminated emission vehicles.
5, comprehensively promote urban and rural waste gas treatment.
"Twelve Five" period, to strengthen the construction site dust management, the establishment of civilized city construction sites and construction dust pollution comprehensive rectification work leading group, the establishment of municipal, district, enterprise level management network.
6, continue to strengthen capacity building.
"Twelve Five" period, the construction of Hangzhou, air pollution control system for continuous improvement, introduced the "Hangzhou pollution prevention provisions of the atmosphere", and the issuance of the annual air pollution control plan and supporting the implementation of assessment methods.
(B) there is a problem
1, ambient air quality improvement into the bottleneck.
In recent years, the effectiveness of atmospheric environmental quality improved significantly, but control "Ambient Air Quality Standard" (GB3095-2012) secondary standards are still gaps.
2. Regional collaborative governance is still run-in period.
The analysis results Hangzhou PM2.5 sources, the contribution to the local discharge air in an urban environment PM2.5 concentration 62% -82%, about 72% on average. Regional transport to urban ambient air concentrations of PM2.5 contribution accounts for 18% -38%, an average of about 28%, in different seasons affect the Hangzhou area varies. A higher proportion of regional transport and complexity of the transmission source region to control air pollution in Hangzhou more difficult to establish and improve regional air pollution is critical institutional mechanisms of joint prevention and control.
3, into the deep water of air pollution control.
In recent years, Hangzhou, air pollution prevention and control work has achieved remarkable success, but there are still many "shortcomings" in the current governance of air pollution, structural, further highlights the deep-seated problems.
(1) optimize the industrial structure needs to continue, heavy pollution in some areas, high energy-consuming industries and the "messy dirty" business issues are still quite prominent.
Total coal (2) Energy consumption is still high, the use of natural gas supply capacity and scale need to be strengthened, industrial parks (industrial parks) are still blind spots of central heating, renewable energy development and utilization efforts still need to increase.
(3) heavy end of the treatment, the light source control and cleaner production, the work of "second five" major emission control measures revolve around the end of pollutants on source control and cleaner production process is still insufficient attention.
(4) With SO2, NOx reduction work continued in-depth, project emissions space shrinking, VOCs emissions is more a lack of technical means, the rigidity of the vehicle population growth, vehicles, ships and non-road mobile machinery and other mobile source pollution control to be a breakthrough. With the difficulty of the work of prevention and control of atmospheric pollution key areas continue to increase, the city is still on air pollution control into the deep water.
4, the basic work is still weak period.
Municipal government attaches great importance to air pollution control work, work-related basis more solid, but there are still many weak links. Hangzhou, organization and leadership of atmospheric pollution control systems should be strengthened, the department division of labor, the working mechanism of collaborative governance needs improvement. Local standards should be further improved, pollution resources and a list of atmospheric pollution still need to be updated regularly.
