Heating knowledge of Hot Water BoilerHot water boiler is a kind of thermal equipment which uses fuel combustion to release heat energy to heat the water in the container so that the water can reach the required temperature (hot water). It is a whole composed of boiler body accessory instrument and auxiliary equipment. The boiler is carried out at the same time in both the boiler and the boiler. After the raw water enters the boiler, the heat absorbed by the boiler is transferred to feed water, and the water is heated into a certain temperature for the user to produce and use for heating. The incessant combustion fuel of the incessant combustor emits heat continuously. The high temperature flue gas produced during combustion can transfer heat to the heating surface of the boiler through the heat propagation, and its own temperature gradually decreases, and at last it is discharged through the chimney. Pot and Furnace division of work, an endothermic, an exothermic, perfect coordination is closely related to an integral equipment, indispensable. Hot water boilers are powered by circulating pumps in operation. The continuous circulating flow of water transfers all the heat absorbed by the heating surface to the raw water continuously, so that the heating surface is cooled well and the water heating foot is speeded up, thus ensuring the boiler heating surface to work safely under the high temperature conditions. In order to ensure the boiler quality and safety, we must choose the regular gas hot water boiler produced by the boiler manufacturer, so that the quality can be guaranteed and the after-sales service can be guaranteed.
Recently, Jinan City issued a "supplementary notice on accelerating the city's boiler-depth treatment of work-related" and formulated the following objectives.
I, on the in-depth treatment of boiler completion time. Low Nitrogen transformation and the transformation of the city's ultra-low emission gas-fired boiler biomass boiler to complete the appropriate time to relax, and strive to be completed in the end of June 2019, due to the commitment of heating (cooling) or involving people's livelihood and other support complex transformation process of the boiler furnace, indeed practical difficulties, completion time may be extended to the end of October 2019.
Second, on the in-depth treatment boiler standards. According to the "program tackling autumn and winter", the low nitrogen gas boiler after transformation, in principle, is not higher than the concentration of nitrogen oxides emissions of 50mg / m³, according to encourage the transformation of 30mg / m³. Encourage the transformation of biomass boiler with ultra low emissions coal-fired power plants.
Third, on the time-depth treatment of boiler arrangement. 2018 10 completed before the end inventory information verification, planning work; organize the implementation of the completion of the work before the end of May 2019; the end of June 2019 to complete the inspection work (due to heating and other disabled do not have to bear the acceptance conditions, available at the end of November 2019 before the completion of acceptance).
Fourth, on the information submitted to the work. Please ring the economy Zi  No. 175 document complements the "Jinan City gas boiler investigation Summary Sheet" on or before October 12, "Jinan biomass boiler investigation Summary Table" to the Municipal Environmental Protection Bureau. On or before October 26, the "Jinan City Boiler depth management plan summary table", "Jinan hole sampling and sampling platform standardization construction unit summary table" and has completed the in-depth treatment of the boiler reconstruction proved supervisory monitoring report submitted to the Municipal Environmental Protection Bureau . Since the beginning of November, every Friday morning before 10:00 (for the first time submitted November 2) the progress of reform in-depth treatment of each unit case to the Municipal Environmental Protection Bureau.
As low boiler heat load case, the flow through the small steam, but the steam turbine requires the corresponding low temperature, generally do not result in too high wall temperatures of the superheater platen, use of time if a desuperheater adjusting the steam temperature control, since the flow of steam after desuperheating water injected into long, the flow rate is very low, the boiler outlet steam temperature the reaction very late pure, easily lead to low-temperature steam, and water may form a plug in the serpentine tube portion. In this case it should be disposed near the secondary steam desuperheater outlet, water in minor amounts, the fine steam temperature.
In schools, teachers and students of drinking water, bathing and winter heating, hot water use these places for hot water temperature requirements are different, but also in the heating season, different locations, different time required to load also different; if hot water boiler for each a heating unit provides the same load, it is easy to cause waste heat, or under heat load situation. Advantages commercial gas boiler in a public gas boiler, highlights out.
