steam boiler induce draft fan

Fourth, the automatic control system of the type with combined boiler, the system can make the water temperature according to the heating curve operation (error ≤0.5 deg.] C), can be truly "heat demand", greatly reducing heat losses and excessive heat under phenomenon.

Recently, Shanxi Province issued a notice "Shanxi win the Battle of Blue Sky 2019 action plan" for the atmospheric environment management direction, the total annual target put forward concrete implementation of the program, as follows.

1, to promote the boiler depth treatment. October 1, 2019, with the province and more than 65 tons of steam coal-fired boilers and located in built-up areas of cities and counties in coal-fired heating boilers, biomass boilers to complete a full ultra-low emissions transformation. Actively promote the orderly transformation of gas boiler low NOx combustion. 2019, the province completed 232 sets of 19060 tons of steam boiler low nitrogen gas Combustion Technology, 40 407 tons of steam boilers ultra-low emission biomass transformation, 907 sets of 4160 tons of steam boiler low NOx combustion gas transformation.

2, continue to carry out special treatment industrial furnaces. The inclusion of 2018 --2019 autumn and winter ban out of the scope of the comprehensive management of air pollution crucial action of industrial furnaces (coal-fired stove in key areas and non-ferrous industry, coal-fired kilns, coal-fired reverberatory furnace, coal-fired lead melting pot and lead electric boiler, coal-fired heating in the cogeneration heating pipe network coverage, kiln drying, etc.) to conduct a comprehensive clean-up, to ensure the elimination ban in place. Expected annual industrial furnaces out of 147 units, industrial furnace-depth treatment of 629 units.

3, vigorously promote clean winter heating. Full use of the complete transformation of the ultra-low emission cogeneration units and large central heating boiler, cogeneration and district heating based, coal to electricity, coal gas and other clean energy sources, supplemented priority to the township as a unit, take piece together the transformation of the way, instead of living and bulk coal for heating.

4, strengthen management and control bulk coal, municipal or county government to promptly clean heating has been completed the transformation of the area designated as a "ban on coal zone" prohibiting bulk coal entering, to prevent the resurgence of loose coal; energy management department should be organized to make clean coal supply protection; market supervision and management departments to increase coal quality sampling, civil bulk coal company coal sales monthly sampling coverage to more than 10%, the annual sampling coverage to 100%.

5, the implementation of total coal consumption control. Optimize the use of coal structure, non-power coal in 2019 substantially reduced compared to last year, accounting for the province to improve coal for power generation coal consumption ratio.

7, shutting down out of substandard small coal-fired units. In the case with cogeneration heating conditions, shutting down the integration of 300,000 kilowatts and heating in the range of 15 kilometers radius of more coal-fired heating boilers and coal-fired units is not up to the small thermal power generating units. In 2019 the province out of 300,000 kilowatts or less is not up to five coal-fired units, 1.02 million kilowatts.

The role and principles boiler deaerator: deaerator divided type head and a headless type deaerator, boiler generally have matching head type deaerator, large units 1000t / h more than the use of non-tower-type deaerator.

The reason the steam boiler induce draft fan Priming phenomenon of the accident causes and solutions Steam Boiler priming accident phenomena and solutions Steam Boiler priming accident, refers to the simultaneous steam boiler soda evaporation surface rises, a large amount of bubbles, a large number of the water vapor is brought out and endanger the safe operation of the boiler accident: a phenomenon; sharp fluctuations (1) water level Indicator water level, there are serious bubble, not see the water level; (2) a sharp drop superheated steam temperature ; (3) severe: water hammer occurs in the steam pipe, the flange steaming; (4) and a saturated steam boiler water salinity increases; Second, the phenomenon of the steam boiler priming process: (1) reduced combustion appropriate, reducing boiler load and remain stable; (2) inform the user of steam to reduce steam consumption; (3) full continuous blowdown door, open the door and turn on the water, if necessary, emergency door sewage regularly to strengthen the boiler water changes, maintain drum level slightly below the normal water level; (4) stop dosing; (5) opening and the present flow furnace superheater steam pipe hydrophobic, hydrophobic notification about the turbine open door; (6) water analysis attendant notification water analysis, the analysis results of the sewage, improve boiler water quality; (7 ) In water is not stable, the water quality is not improved when the furnace boiler applied load is prohibited (8) Note steam temperature change, timely adjustment; (9) Elimination, timely adjustment; (10) fault clearing, the flushing water level indicator controls; (11) boiler water quality standards, clear water level to normal, then resume normal operation of the boiler.

Draft (boiler) - Wikipedia

Forced draft: When air or flue gases are maintained above atmospheric pressure. Normally it is done with the help of a forced draft fan. Induced draft: When air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric pressure. In this case, the system is said to operate under induced draft.

How do induced air fans work and how do they increase furnace

Induced-draft fans pull things through the furnace; forced-draft fans push things through the furnace. Manufacturers began to put induced-draft fans into their furnaces because they improved efficiency by wasting less house air. The beauty of the induced-draft fan system was that we no longer had to rely on gravity to exhaust the flue gases.
