Szl Series Industrial Coal Fired Hot Water Boiler
Vertical steam boiler introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal.
Combustion characteristics and operation of steam boiler steam for steam boilers everyone know how much will the following to let everyone have a preliminary understanding of the steam boiler by two aspects, but also hope to give a friend wanted to buy a steam boiler of some help. Chain-type layer is generally fixed combustible fuel steam boiler chain grate or a grate (the traveling), it is fixed only for small coal-fired boilers. The most commonly used medium-sized coal-fired boilers or for chain grate, as the chain travels will gradually sent to the tail of the coal grate in the process of moving complete fuel combustion tube from the inlet to the lower part of the grate grate internal supplemental air required for combustion, ignition top-down, no ventilation grate uneven seam and around the relative movement, through non-flammable. After heating area of the heating flue gas temperature of the working fluid designed to flow through the same furnace hot flue gas and heating surface arranged in the other exhaust flue boiler. Incidental chain grate type, scale type, beams, and other means, the current domestic applications mainly for small and medium-sized joint type and scale type chain grate, generally large chain grate beam type. Former steam boiler steam boiler system to start all waterproof steam cylinder valve open, let go condensate. The inlet steam valve slightly open, to warm up the cylinder, drain cocks to be out after closing the steam, drain cocks. The steam valve was then opened progressively larger until drainage tank vent cock and water out there, and closed vent cock drain cocks. Turn on the water supply valve to the boiler feed water. Steam boiler in operation if there is gas in timely attention tank, water tank periodically open the air discharge valve, in order to avoid air resistance tank, the influent. Pump flow regulator bypass should be adjusted to achieve the degree of opening of the valve, and not with a method of adjusting the outlet valve is adjusted. At the rated discharge pressure of the pump, which inlet pressure should not exceed a predetermined value. Inlet and exhaust pressure difference should be maintained within a predetermined range. Steam boiler steam valve should be shut down first, then turn off the water valve and turn on the water valve is open, then turn on the water faucet open the lower part of the tank and cylinder, the cylinder water drain. Of steam cylinder reciprocating pump, which cylinder two stroke difference should not exceed 5% of rated travel.
ZG manufactured chain grate szl series industrial coal fired hot water boiler has joined Global Environment Facility (GEF) project. To meet environment standard, experts in ZG Boiler keep innovations and technology developments and successfully launched 1 to 120MW hot water boiler. Our hot water boiler also has widely fuel availability such as coal, biomass, wood, gas, oil, etc. The boiler is supported by the angle tube with high assembly level, but without the steel frame, and it reduces the installation workload at site. The reasonable grate structure and the good air flow adjustment capability ensure the complete combustion and reduce the mechanical incomplete combustion.
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.
