Industrial boilers Defects Defect Analysis industrial boiler analyze the cause industrial boiler plant boiler Class B, rated working pressure 1.0MPa, rated temperature 184 ℃. The use of unit management personnel, operations personnel safety awareness is not high, not strictly enforce the boiler safety management system, boiler water (medium) quality system; the water softener fails, safety consciousness, not timely maintenance. The company location no water, use of pond water. Since untreated pond water containing suspended matter, colloidal matter large excessive, and dissolved substances. Water hardness, long-term use, inside the boiler large amounts of sediment, the carbonate and concentrated attached to the inner surface of the casing pot, water wall tubes; fireman failure to periodically discharge of the sewage system for the boiler. Since the interior of the waterwall tubes attached to a thicker scale, lack of reliable water supply water wall, resulting in performance degradation wall heat transfer, caused by overheating of the metal, plastic deformation strength decreases, under pressure inside, generating bulge, deformation, severe boiler explosion occurred.

Since the Shanxi provincial government issued "on the issuance of the People's Government of Shanxi Province, Shanxi Province to win the Battle of Blue Sky's three-year action plan", cities are actively responding to priorities and deployment. Jiexiu municipal government related departments have carried out remediation phase out coal-fired boilers.

Future, Jiexiu City departments should fully understand the situation of air pollution prevention and control of the seriousness and urgency of initiatives to further strengthen the work, work harder to accelerate the phase-out of coal-fired boilers; comprehensive investigation to the use of coal-fired boilers, find out coal-fired boiler unit, boiler type and capacity, device status, etc. and establish a sound accounting boiler, cleaning up coal-fired boiler plant are out of range, so that base clear, the situation is clear, should be eliminated to make sure that eliminated; to clear objectives and tasks , responsible units, measures, in accordance with the time node in an orderly way, and effectively perform their duties, earnestly implement the clean alternative heat sources, the removal of coal-fired boiler with a new energy escorts to carry out work at the same time; to actively coordinate electricity, gas sector, as coal-fired boiler users to implement clean energy transformation provides safeguards to ensure that coal-fired boilers out of the objectives and tasks completed on schedule, and improve urban air quality, and gradually improve the quality of life of the masses.

Circulating fluidized bed boiler combustion technology is rapidly improving recent years and the CFB boiler combusion technology is very advanced in the world.This technology have been used in China widely.

Equipment maintenance method of a condensing gas boiler, pressure maintenance 1. After condensing gas boiler shutdown the furnace all the water exhausted, the scale furnace, slag clean, rejoin qualified demineralized water. 2. Regular small flame, or periodically using water vapor adjacent to the boiler furnace, the furnace so that the water temperature in the summer condensing gas boiler should be maintained at about ambient temperature of + 10 ℃, winter should ensure that water does not freeze the furnace, close all vent valve, drain valve and drain valve, to prevent leakage. 3. Boiler feed water periodically to maintain the internal pressure of the condensing gas boiler 0.05MPa ~ 0.1MPa prevent air from entering the drum. Second, wet maintenance 1. After condensing gas boiler shutdown at the stipulated time exhausted furnace water, scale, slag, ash cleaned. 2. Close all manholes, hand holes, valves, etc., and the boiler is completely isolated. 3. Prepare a basic protection solution passing demineralized water, boiler water was added per ton of sodium hydroxide Na (OH) 8kg ~ 10kg, plus or sodium carbonate (NaC03) 20kg, plus or sodium (Na2P03) 20kg. 4. The formulated with special pump maintenance alkaline solution into the boiler. 5. When all of the resist solution is injected, the valve opened to fill the qualified demineralized water boiler, until the water overflows from the air valve, and then closing the air valve and the supply valve to open a dedicated pump cycle, a uniform mixed solution. 6. Throughout the maintenance should be periodically maintained with Weihuo drying oven outer heating surface, periodically turn the pump cycle, the concentration of the solution was consistent throughout, but also regularly take the solution assay and the replenishment solution, the PH value of the solution was ~ 10 between 12 to ensure that the alkalinity boiler water. 7. frost winter to take appropriate measures. Third, the dry gas condensing boiler maintenance 1. After shutdown, the boiler water exhausted, scale remove soot, slag and furnace heating surface. 2. Close condensing gas boiler water supply, water supply, the valve on the outfall, or blocked by the separator Yan, completely isolated from the other operation of the boiler. 3. Open the manhole, hand hole, the boiler dry naturally, if the boiler wet, with Weihuo the boiler and furnace wall flue drying. 4. The selection of an appropriate amount of desiccant. Common desiccant anhydrous calcium chloride (of CaCl2) and quicklime (CaO2), CaCl2 2kg per cubic meter of volume of water placed quantitative, requires selection of particles of about 15mm; lime 3kg per cubic meter of the volume of water placed quantitative, requires selection of 10mm ~ 30mm lumps. 5. condensing gas boiler drying, the tray containing a desiccant and the release drum furnace in order to absorb moisture, not in direct contact with the desiccant required boiler heating surface. 6. The desiccant should be checked regularly once placed, heating surface for corrosion to see, the desiccant is failed condensing gas boiler month per week, once a month later examination every two weeks.
