Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type cfbc boiler combustion system advantages paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
Introduction gas steam cfbc boiler combustion system advantages furnace 1 cook, cooking stove main purpose is to remove impurities and grease inside the boiler, when the boiler domestic cooking oven adding the appropriate drugs, furnace boiler water becomes alkaline water, to remove grease and the like other debris. 2, when the cooking stove dosage device should meet the predetermined technical documents, such as when not specified, shall comply with the following table: Note: ①, 100% purity calculated according to the drug. ②, no trisodium phosphate, sodium bicarbonate may be replaced, in an amount of 1.5 times of trisodium phosphate. ③, sodium carbonate may be used alone cooking oven, which was added in an amount of 6Kg water per cubic meter. These drugs should be formulated in a uniform concentration of 20% concentration, the solid drugs can not be added directly to the drum ④, used cooking stove. 3, when the dosing boiler water should be at a low water level. Boiled water should be furnace in high water. 4, the end of the cooking stove boiler pressure should be maintained at about 75% of the working pressure, boiling out usually 2 to 3 days. Medicine name dosage (Kg / m3 water) sodium hydroxide (NaOH) 2-3 trisodium phosphate (Na3PO4.12H20) 2-355, boiling out period, taking periodic laboratory analysis of water heaters, are not low-alkalinity boiler water 45 mEq / l, or should supplement dosing. 6, oven cooking is completed, the drum and the current tank should be cleaned precipitate, and rinsing contact with the liquid inside the boiler through the valve, without clogging sewage check. 7, after the boiler to cool, open manholes, hand holes, rinse with water inside the drum, and check. 8, after the boiler by boiling out, should meet the requirements series: ⑴, no grease drum inner wall; ⑵, after wiping the inner wall of the drum surface should be free of metal deposits rust.
6 tons of steam cfbc boiler combustion system advantages maintenance procedures introduced 1, boiler during operation should pay attention to the following points: (1) does not allow pressurized combustion furnace flame, or easy to damage the door, watching the fire door and unsafe. (2) should be regularly blower, fan, electric water pump fuel. (3) It should be noted arch brick without loss, with or without overflow wall furnace fire phenomenon, identify problems and timely repair, repair shutdown if necessary. The bottom surface (4) shall boiler water to prevent corrosion of the base. (5) The class filter at least once to open check. 2, 2 a boiler operation three weeks should carry out a check. (L) before opening the flue, if smoke tube fouling should be removed, such as less fouling or non-fouling, cleaning time may be the Director, opened once a month, if still no fouling extended 2-3 May start time, checking after each turn, must be locked, shall not leak smoke. (2) Open once each class cleaning door, cleared out the gray tone, without fouling or fill extend cleaning time, according to the actual situation in the hands of fireman, and explore the experience. (3) water gauge, valves, piping, flanges, etc. should be repaired as steam leakage. (4) boiler 2 to 3 months, to the water wall, pipe and be cleared of soot ignition face. Run 3 to 6 months after the shutdown should be all inspection and maintenance. (5) inside and outside of the boiler inspection, such as the partial pressure weld steel corrosion; If it is found serious deficiencies should be repaired, if the defect can not leave shutdown repair, found suspicious, but does not affect when production safety, records should be made for reference during processing. (6) can be checked and the coated portion of the boiler water to prevent corrosion paint. (7) if necessary insulation furnace wall outer casing removed to provide a thorough examination of the prior seriously damaged portion, only after continued use must be rehabilitated, checked and repaired while the person filling the case of the present security technology registration boiler. (8) housing the heat insulation layer (outer sheath), a paint duct at least a year. (9) Maintenance of long-term without the boiler, dry and wet, dry application shutdown more than a month, the following month shutdown can be used wet maintenance method.
The basic principles of coal-fired cfbc boiler combustion system advantages oil-fired boiler needs to change to comply with the Government's strong support for the consolidation of the environment, resulting in a big group of laid-off coal-fired boilers, if these abandoned coal-fired boilers will cause great waste, the coal-fired boiler into oil-fired boiler has become the most economical way, but in their transformation, we have to abide by some basic principles. (1) the transformation of coal-fired boilers must meet the following conditions: ① the original boiler pressure element must be substantially intact, there is value in use; ② original boiler water vapor system and to send, the wind system to be largely intact. (2) After the transformation of oil-fired boilers should achieve the following objectives: ① maintain the rated parameters of the original boiler (e.g., steam pressure, steam temperature, a return temperature, etc.) constant; ② to maintain or improve the output and efficiency of the original boiler. (3) through the transformation of reach smoke and dust, meet environmental requirements (4) boiler rehabilitation programs must be simple, easy, less investment and quick, short construction period. Thus it involves boiler as small as possible, taking only changed the furnace and the combustion device, part of the transformation range without departing from the basic structure of the boiler body. And that is to change the basic principles of coal-fired boiler oil-fired boiler, for our safety you must be the most stringent.
