Experiment On Steam Boiler Thermodynamic

Second, look at the appearance of the gas tank

Sometimes the appearance of the product can react to its quality and value, only the formal strength of the boiler manufacturers will invest a lot of capital and advanced equipment, comprehensive approach to improve the quality of the gas tank, the packaging is no exception.

Steam-gas boiler experiment on steam boiler thermodynamic works with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporize into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source. Boiler and boiler shell consists of two main furnace and ensure accessories, ancillary equipment instrumentation, control and protection system safe and economic operation of its continuous constituted. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube.

Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).

Chemical plant boiler tube rupture occurs comprehensive analysis: chemical plant boiler tube rupture occurs comprehensive analysis of the chemical plant boiler tube rupture occurs a comprehensive analysis of 1, the degree of harm mainly chemical plant boiler explosion occurs tube boiler pipe explosion refers to the smoke tube, water wall tube and damage to the convection tubes. Boiler tubes, steam, irrigated violation, boiler water shortage caused by a short time, if not handled properly, will continue to expand, a serious threat to the safe production and use of living units. 2, squib Analysis (1) poor circulation caused by blockage boiler tubes, resulting in localized overheating of the boiler and the chemical squib occur. Common cause clogging pipes are: water treatment failed, boiler tubes pollution, a new tube through ball without inspection, there is sand and other debris inside the tube or bring yarn, and other debris off the scale. (2) tube local damage, such as a touch or mechanical damage reaches a local recess, resulting in damage to local wear blowing baffle wall (wall off smoke) partial tube is short-circuited, fly close to the furnace wall tube wear flue-speed localized corrosion and thinning the flow tube, and the like. (3) Pipe manufacturing defects, such as poor quality welding, the structure is irrational, inextensible tubes and the like. Local temperature changes (4) of the pipe is large, resulting in cracking of the pipe, as will water improperly treated, fire, water temperature is low, into the boiler with the boiler water and poor mixing. (5) Slagging not promptly removed, fresh water after improper handling, improper firing uneven heating of the tube, a low water temperature, the mixing pot into the boiler water is not good. (5) Slagging not removed, resulting in uneven heating, water circulation damage. 3, chemical treatment of boiler occurs squib (1) reduce the load to stop blowing, increased water supply, the water level is maintained, and immediately reported to the leader according to the normal shutdown process. (2) water level gauge can not keep the water level, when the water level unseen, should immediately stop the water, emergency stop hearth, but should continue to operate, so that the smoke and steam discharged from the furnace.
