4 steam cycle in boiler steam plant

Fan 4 steam cycle in boiler steam plant uses coal boiler using a mechanical energy to heat, then the boiler must use such equipment in the ventilator during use. Today, we are concerned that the role of the fan in the boiler. Boiler fan is chosen depending on the model and specifications of the boiler in the selection, but fans can also play two different roles in this area, but on the principle that ventilation is still the same. Device for conveying air into the boiler is fan. If you want to use coal for greater efficiency in the boiler, we need more oxygen. Since the boiler is in the shape of a hermetic shape, it is not possible to allow the air to the boiler initiative complete combustion. This time we should use the power boiler fan, the air supplied to the boiler which mechanically energy, in order to make coal in the boiler more complete combustion to provide more heat.

Boiler feed water temperature on the steps and 4 steam cycle in boiler steam plant: boiler awareness and understanding, the following questions and answers will be used to form, that is, give some specific issues related to the boiler, and at the same time to explain and answer, so, to make themselves have achieved, and to grasp new knowledge content, in order to study on their way, to make progress and development. 1. Boiler so, what specific steps?

Steam 4 steam cycle in boiler steam plant furnace Henan cook fast boiler's steam boiler small series with you about the cook stove. Clothes, steam boilers or overhaul after reassembling formally voted before the furnace should be cooked, to remove the pot rust, oil and other impurities, the inner surface of the heating surface to form a protective touch, and corrosion can be prevented to ensure the quality of steam. Steam cooking oven according to boilers using manual work requirements, and note: dosing an amount of 1; dosage level of the boiler water and the dirt capacity, the nature, the general dosage per ton of water was added sodium 2 ~ 4Kg , tribasic sodium 2 ~ 4Kg, dissolved into an aqueous solution, the air valve is opened boiler, boiler water filling to the lowest security level. 2. Steam boiler furnace during cooking; furnace should have a higher boiling water, cooking time depending on the capacity of water to the boiler furnace may be, usually 34 hours, for steam boilers in 4t / h can be reduced to 20 hours, particularly boiled furnace process generally as follows: <1> 0.2-0.3MPa ignition switch is pressed to 1 hour, at a base 0.2-0.3MPa cooking 6-12 hours (depending on the boiler capacity), while the heat bolts; 50% as for boosting working pressure for 2 hours dwell at this pressure for 6-12 hours (depending on the capacity of the boiler). <2> test boiler water; supplementary water supply and sewage should be repeated during cooking oven, boiler water taken every 3-4 hour assay, full analysis of alkalinity boiler water and acid content, alkalinity when full <45mmol / L replenish added drug, a phosphate content of post furnace stability to boiling, boiling out side that after passing shutdown 4-6 hours run at the original pressure until the boiler water temperature is below 75 ℃, boiler water may be excluded, then rinse all contact where liquid and clean. <3> boiling out eligibility criteria: a steam boiler surface without grease, rust, and form a black alkaline metal surface protective film boiling out qualified, or until a response to the second cooking oven pass up. (1) overpressure: Due to the illegal operation, safety accessories safety interlock protection device malfunction or failure of Ge, the operating pressure of the boiler drum rather than withstand the pressure of an explosion. Pressure element (2) of the boiler itself defective or damaged, under pressure to reduce its own boiler explosion caused.

Recently, Nanchang, Jiangxi Province to fully implement the national environmental protection work conference and the province's environmental protection work conference, combined with the actual situation of the city, issued a "blue sky Nanchang win the Battle of three-year action plan (2018-2020 years)" (referred to as " plan"). "Plan" put forward a management plan for major air pollution problems.

As the relevant departments to actively promote the utilization of clean energy. The city gradually reduce the proportion of coal consumption, by 2020, coal accounted for the proportion of energy consumption dropped to below 65%; principles and has gradually increased the proportion of natural gas energy consumption, adhere to "the electric power should", "should air the gas" to promote natural gas work to build the pipeline, steadily "coal to gas" project.

2018, the main city of Nanchang to the new area, the main city area and open small blue through the open area to expand the range of city ban on burning areas. By the end of 2020, Nanchang County, Jinxian, Anyi required scoping combustion zone ban within the jurisdiction of, and informed consent of the uniform implementation of the municipal government.

"Plan" put forward in 2018, the main city of the new areas into the combustion zone ban, the main city through the open area and a small blue through the open area phasing out the 10 steam tons / hour and coal-fired boilers; 35 tons of steam launch built-up area / out of hours and coal-fired boilers. As of 2020, the city built basically out of the region 10 steam tons / hour and coal-fired boilers, coal-fired boilers within 10-35 tons of steam / hour range is substantially complete alternative clean energy sources, and no longer approve new 10-35 steam tons / hour of coal-fired boilers.

Steam Engine. Steam enters the turbine with high energy content and leaves after giving up most of it. The high pressure steam from the boiler is expanded in nozzles to create a high velocity jet of steam. In any type of steam engine, it is the VELOCITY of the liberated steam, and NOT the pressure, which produces the force which causes rotation of the shaft.
