once through steam boiler

It is understood that, recently, the ecological environment Department of Henan Province issued the "Henan electricity in 2019 non-standard governance program industry" and six special programs, mainly to further promote the campaign of air pollution control, to ensure that the province's ambient air quality continues to improve. Meanwhile, the "plan" also made clear this year Henan Province industrial air pollution control in key tasks.

The province meet the conditions of steel, coke, cement, carbon (including graphite), flat glass (including electronic glass), aluminum and other six major industries and enterprises, the requirements before the end of this year to complete the mentioned standard treatment, the required limits for reducing pollutant emissions. Carry closed down or banned brick kiln, lime kiln, tunnel kiln, firing kiln and a variety of smelting furnace, roaster and so on nine categories of Kiln, upgrading, restructuring and integration work. Before the end of October this year, all kinds of industrial furnaces to achieve discharge standards.

Before the end of June this year, the province's petrochemical, oil refining, industrial coating, packaging, printing, chemicals, pharmaceuticals and other industrial enterprises, the full completion of volatile organic compounds pollution control; before the end of August, the province's petrochemical, oil refining companies to complete volatile organic compounds depth governance and leak detection and repair of governance; before the end of December, the provincial cities of built-up areas phasing out the open dry-cleaning machine.

Before the end of October this year, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province completed 35 steam tons / h coal-fired boilers and the removal or clean energy transformation, provincial cities and county (city) district built 4 tons of steam and above gas-fired boiler, fuel (including alcohol-based fuel) boiler low nitrogen transformation complete, the provincial municipality to build a biomass boiler area (including biomass power plants) completed the first ultra-low emissions transformation. Before the end of June this year, the completion of the provincial cities to build coal-fired facilities Chaigai all industrial areas.

Means decontamination method on an electric boiler of: facilitate the use of electric boiler of our lives, to enhance our quality of life, but after some time the electric boiler will produce use dirt, remove dirt electric boiler, following these steps.

2.High pressure and high temperature, convert the mechanical energy to electricity energy high efficiently.

3.Compact structure, small occupation, save the cost of boiler house.

Extend the life of the boiler shutdown maintenance (auxiliary boiler) after the end of the heating period, the heating boiler has shutdown of more than six months a year, stop running such a long period in the boiler, if the units do not pay attention to maintenance of the boiler, establish and improve various rules and regulations do not or do not take proper care measures, it can easily cause corrosion in the boiler, the life of the boiler and therefore will reduce the economic efficiency of enterprises will also be seriously affected. So strengthen the maintenance work during the shutdown of the boiler, it is of great significance. 1. Grate: Grate pad wear Check the boiler fouling cleared up the middle slot, if necessary, replace the grate. Grate front axle oil level check, timely lubrication. Check whether the switch lever grate Flexible damper sides. Start fan running for 20 minutes, to grate fouling purge. 2. reducer: the oil discharge portion open vent hole, where the oil quality was observed. The need to replace all the oil inside the gear if necessary. 3. blowers: Open inspection hole fan, check the fan wear, if worn on the need to re-adjust the fan balancing. Fouling bottom clean-up fan housing. Check the oil level air quality timely replacement of oil, add oil. Pairs of primers were cleaning the bottom of the blower housing. 4. Cleaner: to take over the slag discharging ditch water submersible pump, a chain wear Cleaner inspection, replacement of the flap chain if necessary. Check the Cleaner head bearing box oil level, add oil in a timely manner. 5. Dust: Internal precipitator for dedusting treatment. 6. Air Compressor: Check compressor oil, timely oiling. After the dust clean-up is complete, turn on the air compressor to purge the filter to work. 7. Chimney: open the bottom of the chimney, cleanup internal fouling. 8. decontamination: the decontamination out of the water valve closed, open decontamination hand hole, decontamination of sludge within the debris clean up, clean-up after the completion of the closed hand hole, out of the water valve and open the drain valve decontamination for decontamination flushing. After draining off water until the drain valve. 9. Valve: pump room and boiler room on the check valve, leaks, opening and closing is flexible tight.

Once-through Boiler Steam Temperature Control Using Dynamic

Boilers are divided largely into once-through boilers and drum boilers, depending on whether they are equipped with a drum or not. The once-through type has been preferred over the drum type because it is operable at a higher pressure and provides highly efficient heat-exchange cycles. In addition to

what is the difference between drum type boiler and once

Jan 22, 2009 · Drum boilers are also called sub-critical boilers because they have to operate below the critical point of water to make sure there is a density difference between the steam and water, allowing for separation. In a once-through boiler, all of the water that enters the boiler is turned to steam.
