High quality electric heating wire jacket thickened stainless steel pipe, filled with high purity magnesium dioxide powder, long service life of electric heating tube. Each group of electric heating components adopts flanged connection, which has the characteristics of simple structure, high mechanical strength, safety and reliability, convenient replacement and so on. 7. The electric steam boiler is compact in structure, scientific and reasonable in design and advanced manufacturing technology, which makes the boiler take up less space. Convenient transportation and saving site. 8, electric steam boiler is noise-free, pollution-free, high thermal efficiency, boiler body uses high-quality and high-efficiency insulation material as insulation, heat dissipation is small, energy saving and consumption reduction. 9, outside the electric steam boiler Packaging using famous color board package design, beautiful appearance, not easy to rust.

Gas papermaking atmospheric pressure water tube boiler manufacturer steam introduced: Introduction steam-gas boiler; steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporize into steam the thermal energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. Features: 1, the steam boiler burner gas supplied by well-known manufacturers in the world, burn automatically stop controller in accordance with instructions, a separate control box has a number of security, safety and stable performance, low maintenance. 2, advanced automatic steam boiler controller, Chinese LCD screen, the man-machine interface, the user simply easily set, i.e., according to user requirements boiler start and stop, load adjustment, automatic water supply, such as automatic operation. Boiler fully functional, complete protection, easy to operate, safe, reliable, self-diagnostic function. Boiler operation anomalies automatically interrupt burning, audible alarm once appeared. 3, vertical steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. 4, horizontal steam boiler shell type three return all wet back downstream pyrotechnic tube structure, economy. Waveform threaded pipe and furnace structure and improve the strength of heat absorption of the boiler, the heating surface needs thermal expansion. 5, in strict accordance with the present boiler "Steam Boiler Safety Supervision", JB / T10094-2002 "industrial boilers general technical conditions", JB / T1619-2002 "boiler manufacturing technology conditions potshell" requirements, design, manufacture, monitoring inspection to ensure good quality of boilers, achieve low energy consumption, high thermal efficiency, stable pressure, gas and quantity, economic use. 6, a large boiler furnace space, storage, steam and more adaptable load capacity. Rational design of steam separator apparatus built to meet user requirements need to use higher quality steam. Furnace open manhole, head holes, hand holes, to facilitate the internal furnace to clean up, make repairs, maintenance is very convenient. 7, is provided with a multi-stage boiler safety interlock protection: Pressure switch protection (higher than the set auto stop and pressure), low water protection (boiler water level is below the body of the warning level, the alarm and automatically cut off power), the protection valve (boiler pressure exceeds the pressure of work, discouraged automatic blood pressure) to ensure foolproof boiler in a variety of conditions, safe home. 8, the combined organic appearance of mechatronic, sophisticated new, compact, less space, easy to transport and install. 9, using the new material and the thermal insulation quality white color plate package, lighter in weight, good insulation properties, beautiful, not rust. 10, automatic / gas steam boiler is widely used in hospitals, schools, textile mills, garment factories, clothing stores, garment factories, dry cleaners, restaurants, hotels, bread stores, hotels, canteens, restaurants, food plants, beverage plants, soybean plants, meat plants, canneries, wineries, pharmaceutical, packaging factory, building materials factory, paint factory, beauty salons, bath, sauna, steam room, baby swimming pool and other enterprises place.

Chemical Plant Boiler Water Wall High Temperature Corrosion What types of chemical plant papermaking atmospheric pressure water tube boiler manufacturer water wall high temperature corrosion types are there? Chemical plant boiler water wall appeared high temperature corrosion phenomenon is a complex physical and chemical processes, analyze the mechanism of corrosion can be divided into sulfate type corrosion, corrosion in chloride and sulfide corrosion three types. 1, the sulfate corrosion occurs mainly due to corrosion is sulfate type like corrosion in the boiler water wall portions of the raw coal combustion to generate a basic substance pyrosulfate and sulfate compounds such as by a chemical reaction, the corrosion process usually have junction slag or the like coking phenomenon. 2, chloride-type corrosion in recent years, many scholars have conducted research, and have achieved fruitful research results. The results showed that when the high chloride content of the fuel, will produce a certain amount of hydrogen chloride in the boiler, and the boiler corrosive effect [3-5]. Coal boiler test results show that the chemical, the chloride content is less than 2/10000, the production of coal combustion is much smaller than the chloride content of chloride corrosion is generated, therefore, not because water wall temperature corrosion caused by chlorine contained in coal of. 3, sulfide corrosion combustion zone in the furnace within the range, when the unburned flame to the water wall erosion due to chemical action, unburned fuel will consume large amounts of oxygen, so that the outer surface of the waterwall vulcanized occurrence corrosion.
