Szs structural features and gas hot water type water tube boiler of a hot gas pipe sz series of drum water boiler waterwall convection bank smoke condensate recovery chamber and the fuel combustion furnace, the flue gas convection bank into the chimney flue gas condensation recovery. Slight positive pressure of the fuel combustion in the furnace, high temperature flue gas enters the flue turn back along the furnace tube bundle, through pre-compression into a second cigarette bundle 180 enters the second bundle. After the convective heat transfer, flue gas emissions into the atmosphere. A corrugated structure with full combustion furnace, the flue gas only enhance the disturbance, increased radiation heat transfer area, increases the rigidity of the furnace, effectively reduces the expansion stress of the hearth, increase the heat transfer effect. It also promotes the combustion of fuel in the furnace, using a pre-expansion, all welded, expanded advanced technology, both to prevent corrosion of the pipes a gap, but also improves the welding strength, using threads having a high heat transfer coefficient of smoke tubes improve convective heat transfer. Reducing the exhaust gas temperature, the thermal efficiency of the boiler increase. Features szs type gas hot water boiler 1, reasonable structure and layout of the boiler, the boiler can be assembled 10 tons shipped. 2, a large number of heating zones. Boiler heating area, an output; 3, advanced PLC control system, clear, practical. 4 ,. using advanced imported burner, fuel burn rate, reduce the cost of enterprise economy. 5, the structural design of the boiler is reasonable, low requirements for the construction of the boiler room, boiler selected according to the actual conditions, reduce procurement costs.
According to instructions, "Neijiang City in 2017 and phase out coal-fired boiler desulphurization facilities construction program of work", before the end of this year, the city built-up area will be fully phased out in Neijiang City, 10 steam tons / hour of coal-fired boilers and a total of 46 units. Among them, a small city in district out of coal-fired boilers 26, and phase out coal-fired small boilers Dongxing District 15, Neijiang Economic Development Zone small coal-fired boilers out of five. At the same time, accomplish four Chuansha Qi Industrial Co., Ltd. Two 20 tons of steam / hour or more coal-fired boiler desulphurization facilities. A ban on new urban area 20 steam tons / hour of coal-fired boilers, other counties (cities, districts) in principle, the new 10 steam tons / hour of coal-fired boilers. Out of the way including demolition scrap, coal to gas, coal and electricity upgrade boiler swap with large capacity.
We understand that the new Neijiang 20 tons of steam / hour for coal-fired boilers built-up areas, the new 10 steam tons / hour or less fixed asset investment projects in other areas of development and reform, economic and information technology departments will not be approved, approval and filing, environmental protection departments at all levels shall not pass environmental impact assessment, quality supervision departments at all levels do not accept the installation told not arrange supervision and inspection, no special equipment issued registration certificate. Quality supervision departments at all levels cancellation of special equipment for the boiler has been out of use registration certificate to prohibit the production of boiler manufacturers boiler does not meet industrial policy.
Gas-fired commercial hot lss vertical tube steam boiler is the main boiler of commercial water and residential water. However, from the point of view of boiler explosion and boiler corrosion in recent years, many steam hot water boiler workers are not very familiar with the maintenance and use of Fangkuai boiler or maturing boiler. Therefore, the water quality standard of steam hot water boiler is introduced firstly by the electromechanical technicians in this paper. 1. The installation requires the installation unit to have the technical strength before the installation, carries on the installation construction organization design, formulates the installation construction network plan. Supervisory engineers shall organize design, manufacturing and construction units to communicate and coordinate technology according to the specific conditions of the pumping station. Installation After the design audit of the construction organization is approved, the supervisory engineer will issue the start-up order, allowing the construction unit to enter the site for installation and construction. Set up construction units, establish a single project responsible person, clear the scope of responsibility, unified command. Installation personnel should study technical materials, familiar with drawings, master procedures, specifications and related technical procedures, master installation steps, methods and requirements, so that the installation quality meets the design requirements. 2. The installation plan is the main part of the construction work. The contents include: installation process, installation work plan and so on. The installation plan and construction schedule should be clearly defined in the installation plan. List Identify individual projects, sub-projects and their quantities throughout the project. The main, middle, first and second phases shall be separated, and then reasonably arranged for the construction period, personnel composition and various construction stages. The main task is to get the progress of each project to work together and connect with each other. The main requirements for gas-fired steam boilers are as follows: 1. When the rated evaporation of the boiler is greater than or equal to 6 t / h, the boiler shall be degassed. If the rated evaporation capacity is less than 6 t / h, if the local corrosion is found, the water supply should be deaerated and the oxygen content of the feed water of the steam turbine boiler should be adopted. Should be less than or equal to 0.05mg / L. 2. If it is difficult to determine the dissolved solid, it can be indirectly controlled by measuring conductivity or chloride ion (C1 -), but the relationship between dissolved solid and conductivity or the ratio of chloride to Cl- should be based on the test. Yes. The ratio relationship should be periodically re-tested and corrected. 3. The relative alkalinity of the fully welded structure boiler can be controlled. 4. Steam hot water boilers with rated evaporation of less than or equal to 2 t / h and steam hot water boilers and steam water boilers with rated steam pressure of 1.0MPa or less (such as no special requirements for steam and water quality) can also be treated in pots. However, it is necessary to monitor Steam hot water boiler scaling, corrosion and water quality, and make ingredients, sewage and cleaning work.
Steam boiler blowdown and the need for the kind of price: a commercial hot lss vertical tube steam boiler in the boiler, it can be said, it is a common boiler, and its Web site is one of the products, so, based on this, the following will continue its study and understanding, so that we can continue to learn in order to achieve the intended learning objectives and requirements as soon as possible. 1. steam boiler, which is the need for sewage? Steam boiler, which is the need for sewage, so, on this issue, the answer to that is yes, because, no matter what kind of boiler, sewage works are to be carried out, otherwise, it will affect the normal operation of the boiler and use, and thus shorten the life of the same. The blowdown steam boiler, which is specifically, it is: in a steam boiler, which should be regularly or more alkali salt of internal boiler water, and water, sludge and the like precipitate excluded, such that boiler water compliance requirements. The completion of this process is the boiler blowdown.[email protected]
