4Th Diesel Fired Boiler

4Th Diesel Fired Boiler

How are gas-fired 4th diesel fired boiler explosion, and what means can suppress explosion

Since spring, our Tai'an, Shandong, Sichuan Mianyang and other places have occurred in a boiler explosion, causing casualties and damage a large area, as well as serious adverse social impact.

Boilers are widely used, and there are some unique problems in China. Although imported 4th diesel fired boilers are used in some plants, the pipeline is still carbon steel, oxygen corrosion and CO2 corrosion are serious, resulting in the problem of iron ions in condensate water exceeding the standard is very common. High content of iron ion water is an unsafe factor in boiler, which causes pit erosion and pitting corrosion of boiler wall, and causes boiler perforation to be scrapped.

Fuel gas steam 4th diesel fired boiler cleaning methods and maintenance Comments? Necessity boiler steam boiler fuel gas washing operation over a long period, the inevitable emergence of scale, the problem of corrosion, boiler scale formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation in an oven within a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale. Maintenance 1 gas fuel steam boiler, gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. 2, feed water temperature should be as close to the furnace temperature, preferably above 20 ℃. 3, the low water cutoff for periodic inspection and maintenance and cleaning apparatus. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4, requires periodic operation of sewage per day (per shift) at least once, you should check whether the sewage drain valve due to possible contamination and leaks; if it must be excluded. 5, when the steam pressure is not maintained while the shutdown, the steam boiler space air entrapment generates negative pressure, and therefore should rise again to the fire burning total steam valve is opened. 6, after the smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.

Fangkuai Group insists on using sophisticated equipment and technology to ensure operation accuracy, increase rigidity and surface finish, reduce wear, ensure excellent performance, and ensure stable and reliable manufacturing quality. It has a domestic Class A 4th diesel fired boiler manufacturing license issued by the General Administration of Quality Supervision, Inspection and Quarantine. It has been based on quality for many years and has obtained a number of authoritative quality certifications.
