Regular maintenance of electric boilerIn general, the electric boiler should be repaired and maintained within 1 ~ 2 years, which is helpful to the normal operation of the electric boiler. For the electric boiler, regular maintenance is also the basic to ensure its normal operation. 1, when maintaining and maintaining the boiler, Must cut off the power supply, must release pressure. 2, burners should be removed from the boiler body every two months, carefully remove carbon deposits and dust and other foreign matter. The photo-electric tube is polished once a month. The fuel filter should always be cleaned and filtered. Carefully clean the inner filter screen of the oil pump and do not destroy the gasket. The burner shall not be idle without oil to prevent damage to the oil pump. 3. The water level gauge shall be kept clean at all times. Open the cleaning valve once a day to keep the water level clear. 4. The safety valve is pulled once a day in case of rust failure. After the work, check if the tools, materials, accessories are complete, to prevent remaining in the furnace and other spaces. Special person delisting, acceptance and acceptance of qualified before leaving the work site, final maintenance records, in order to prepare after the inquiry.

Boiler cleaning the necessity and significance of the boiler after a long run, the inevitable emergence of scale, corrosion problems, these problems are due to the generation of scale, so that the heat transfer deterioration, resulting in reduced efficacy boiler. It is difficult to achieve nominal evaporation; and since the heat transfer is deteriorated, such that the metal overheating, under pressure boiler, furnace tube bulge occurs even explode; poor thermal conductivity, so that the fuel consumption is increased, increased operating costs, boiler shortened life expectancy. Therefore, the boiler scale, should take the necessary cleaning methods. Of the boiler system operated at optimized state, it must be specialized chemicals treatment of boiler system water system: to remove scale, rust and anti-corrosion treatment: 1 chemical cleaning: adding a chemical cleaning agent to rust in the system , dirt, cleaning oil dispersion is discharged, reduced to clean metal surfaces; 2, routine maintenance: boiler scale inhibitor is added, to avoid rusting of metal, to prevent the crystalline precipitate calcium and magnesium ions. Boiler cleaning in two parts, part of convection boiler tubes, superheater tubes, air heaters, waterwall tubes scale, rust cleaning, i.e. wet back fire tube water boilers water treatment, we used the final Li Jing Ling descaling operation, neutral cleaning technology cleaning operation, relatively low cost; cleaning of the part of the outer tube, i.e. the cleaning of the boiler furnace, we used high-pressure water jet cleaning technology, it is possible to achieve good results. 1, the cleaning operation may be neutral at neutral or weak alkalinity (pH 7-12) conditions, the water does not change the operation of the boiler a predetermined state index, do not stop cleaning, cleaning can reduce the loss caused by the stop, this is a the only signs of cleaning. 2, security theory and practice of running the boiler have proven non-erosive, washed acid-free cleaning under neutral conditions, the corrosion rate is less than the water washing of the corrosion rate of the metal, no corrosion damage to the metal. 3, non-toxic and pollution-free operation of the Spirit is a green cleaning products, boiler blowdown COD after its cleaning. BOD. The pH full compliance with national standards. 4, easy to use drugs added to the water supply can be, without a separate professionals, post operator can operate, it can be widely used. 5, a significant saving, the cleaning process in which water is the normal production water, unlike dispensing additional consumption pickling, passivation, and a large number of repeated washing of freshwater resources consumed. High pressure water jet cleaning technology uses water as the medium, so that the water system by special equipment to produce multi-beam, multi-angle, high-pressure water jets of different intensity. Internal cleaning object fouling, plugging, or be completely cut surface adhesion, crushed, pressed and washed in order to achieve complete cleaning. Whatever the fouling deposits, high pressure water jet cleaning device for cleaning, can be completely removed, which considerably metal color. It does not require chemicals, or corrosive flux, safety, and environmental protection. Boiler air preheater, waterwall, superheater, economizer heating surface and the like due to clogging of the exhaust gas temperature, boiler efficiency is lowered, increasing the wind electrical energy consumption; the fan will cause severe blockage afford pulling negative pressure oxygen furnace not enough, boiler forced outage. Using high pressure water jet technology, the cleaning effect is obvious. Equipment from high pressure water pump, water hoses, high pressure gun, special nozzle and other components. Cleaning process: water pressure via a high pressure pump to the 50 ~ 100Mpa, via line transferred to the system actuators work surface, forming a bundle of fine high-pressure water emitted from the nozzle with a high pressure water jet but powerful strike capability, which exit velocity up to 380m / s, the heating surface fouling rinse. The high pressure cleaning technology to clean, easy to adjust, cleaning equipment to be non-corrosive, non-polluting the environment, the effect is obvious characteristics, is an effective and a good way to save money and effort, especially suitable for solving air preheater clogging, severe coking furnace heating surface slagging problems. Generally reduce exhaust gas temperature of 4 to 12 degrees, the main improved reheat steam temperature of 0.5 to 5 degrees, to reduce electrical energy consumption for the wind, and early detection of creeping inflation, under scale corrosion risks, the unit safe and economic operation of very help.

4tph WNS gas-fired firetube boiler project for food industryBoilers are mainly used to provide steam for drying, refining, destaining and other processes in the productive progress of edible oil. As a children company of AnHui COFCO Biochemical, AnHui COFCO Edible Oil Co.,Ltd. is founded on 2000, producing premium quality edible oil from corn germ, rapeseed, peanut, soy bean etc.. In order to develop the circular economy, COFCO has taken an active part in energy saving and emission reduction these years. The company adopts reliable and advanced waste water treatment system, meanwhile, the environment protection facilities also produces ammonia sulfate, feed and methane as by products. Therefore, they’d like to use desulfuration methane as the fuel for boiler to improve economic returns. They have planned to order one set of methane-fired boiler. ZOZEN’s WNS series firetube boilers have drew their attention by remarkable performance. This kind of firetube boilers is adaptable for various fuels, including natural gas, methane and coke oven gas. Large corrugated furnace is adopted for complete combustion. Meanwhile, engineers of ZOZEN also add the condenser, economizer and other energy-saving equipment at the end of flue gas duct in accordance with actual demand of the company, which makes the thermal efficiency reach above 98%. Furthermore, it equips with advanced combustion apparatus for lower NOx emission.
