Boilers can be further broken down into fire tube and water tube boilers. Once this is over, make sure that the boiler is piped properly and that both the boiler and system pumps are running smoothly. May be found at locations of higher external stresses, such as near attachments. Problem with the gas/air mixture: Make sure that the vent/air intake lengths do not surpass that of the maximum as instructed in the manual. Solutions: For fly ash erosion, distribute flow evenly through the boiler and consider burning a lower ash fuel. Please can you help. Occasionally, customers have had issues with the pump not being functional. Solutions: The most straightforward method to reduce fuel ash corrosion is by using materials with higher chromium concentrations. @Francis: Do check the article which explains the reasons for boiler not firing. Ignition failure Flame failure after 5 tries to restart. leakage in the condenser) Fuel Safety System: The boiler is provided with heavy or marine gas fuel oil for generating the heat in the furnace.

Symptoms: External tube metal loss (wastage) leading to thinning and increasing tube strain. Components typically affected: Superheaters and reheaters. For this reason, you should clean and inspect your fuel oil strainer weekly. Pilot ignition transformers are maintenance-free and can last several years, but their life can be shortened by faulty cables. It seems like I might have problem wiht the regulator. Gain access to our free AOP (Ask a Professional) Section to get real answers for your questions. Biasi Boiler Error Codes, Faults, Problems & Fixes | Boiler Central The most common pump type is a centrifugal pump. Your flame scanner may operate via UV, visible, or infrared light signaling. A failure tends to be catastrophic as the entire tube will fail across the circumference of the tube section. In the event of failure, steam traps will either be closed or open. Just like any other troubleshooting, this one has solutions too! A thermal imager can easily and quickly calculate the temperature of the pipes, and diagnose whether or not the steam trap is operating properly or needs repair. Reply 12-18-2007, 11:24 AM #5 anna conda Regular Guest Join Date May 2006 Posts 65 In cases where sootblower steam is the primary cause, the erosion may be accompanied by thermal fatigue. If a value is damaged or blocked, this can prevent gas from entering the chamber and mean your boiler wont ignite. With sensors, compare a reading at the diagnostic test equipment to the reading of the actual sensor. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Protroubleshooting.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by linking to Amazon.com, Brother Printer Stuck In Sleep Mode (Quick Solutions), Factory Resetting A Brother Printer Made Easy, How to Fix Canon Printer Printing Slowly In Windows, Epson Printer Offline on Windows or Mac (Easy Fix), How to Reset Reset Epson Printer to Default Settings (Simple), Canon Printer Printing Blank Pages (Quick Solutions), Chain Drive Vs Belt Drive Garage Door Opener. Is power generation taking place? Here are the five most common reasons your boiler fails on ignition or pilot. To fully understand the cause of the failure, you must investigate all aspects of boiler operation leading to the failure in addition to evaluating the failure itself. Another major area where diagnostic equipment is vital in a boiler plant is the electrical system. The failure of a pump can cause the shutdown of a critical process or area. Steam traps should be tested several times a year for proper operation. In some instances, where caustic gouging along the top of a sloped tube is associated with steam-water separation, such separation can be avoided by use of ribbed tubes. Boiler firing on MGO but fail to fire on HFO. Acid damage: When the pH of the water is too low, the water is acidic. Causes: Long-term operation at relatively high metal temperatures can result in damage in carbon steels of higher carbon content, or carbon-molybdenum steel, particularly in weld heat affected zones (HAZ), and result in a unique degradation of the material. Did someone accidentally close the manual oil or gas valve? In addition, flame failure can increase the risk of carbon monoxide poisoning. Regardless of any faults, these cables should be replaced annually as part of your routine maintenance schedule. Like other types of equipment found in the central energy plant, boilers and auxiliaries have many variations. Symptoms: Failure is brittle with a thick edge fracture. Weil McLain Ultra Boiler Problems [7 Easy Solutions] - FireplaceHubs A high carbon monoxide reading demands immediate ventilation and equipment shutdown and checkout to determine the source and cause of the carbon monoxide. Some of these may seem similar to the symptoms of an ignition failure; however, the causes of the failure are distinct.

You can check a flame sensor by measuring the milliamp output of the sensor when it is exposed to the boiler flame. Corrosion-resistant thermal sprays may also be considered for this application. Symptoms of boiler flame failure include a sudden decrease in heat output, an increase in smoke production, and a rise in flue gas temperature. Solutions: Use available graphitization prediction curves to determine locations that are at greatest risk. Causes: Erosion of tube surfaces occurs from impingement on the external surfaces. take out the pilot burner and check its functioning. @Danne: Do check the nozzle of the pilot burner for the angle and length of the spray ( as per the manual). Causes: It occurs where a combination of high-tensile stresses and a corrosive fluid are present. We look forward to hearing from you. Hello, i have an Auxiliary Boiler RP-400M-I burner from Kangrim and i have the follow problem : I am ruining on MDO and yesterday during day time we received alarm Flame Failure, we opened the burner checked electrodes(were OK) and clean all the filters, after restart boiler fired for around 14 hours.
