steam boilers and drying oven manufacturer
1. The type of boiler scale type of boiler scale (1) an alkaline earth metal scale: comprising calcium as a main component of scale, scale such as calcium sulfate, calcium silicate scale, calcium carbonate scale and the like, magnesium as a main component, such as hydrogen hydroxide scale, dirt and other magnesium phosphate. (2) the dissolved iron: comprising iron as a main component of scale, dirt iron oxide, iron silicate and a dissolved iron phosphate scale. (3) Aluminum scale: aluminum as the main component is a scale, such as aluminum silicate scale. (4) Copper scale: copper as a main component is a metal of scale. Calcium sulfate scale hard and dense, low pressure in the boiler arrangement, mainly in the form of gypsum or hemihydrate precipitate is attached; in the boiler body, in the form of an anhydrous compound precipitated attachment. Calcium silicate scale mainly in the larger heat load boiler heating surface is formed, which precipitate as wollastonite, large scale hardness, poor thermal conductivity, can be firmly adhered to the heating surface. Carbonate scale have different characteristics, it may be both hard scale, and may be soft water residue. When the boiler water evaporated weak, often carbonate crystals precipitated into a hard scale. When the furnace violent boiling water, carbonates and often precipitate water residue. Magnesium hydroxide and magnesium phosphate easily adhere to the wall of the boiler, the formation of secondary scale. Most scale component is an alkaline earth metal scale (90%), as well as iron scale, scale aluminum, copper, dirt and other organic and metallic corrosion products and the like. By scale formation procedure can be divided into two types: one is a scale salt impurities formed by direct crystallization of the heating surface; one easily adhered slag heating surface, secondary scale again. Slag is divided into two, in addition to a water-slag easily adhere to the heating surface, the formation of secondary scale is difficult to remove by mechanical means, but there is a slag flow state was difficult to adhere to the heating surface in execution a method in accordance with the sewage discharged.
As we all know, natural gas boiler with high thermal efficiency and clean environmental advantages, are popular. The difference in the output medium, a gas, gas-fired hot water boiler, a steam boilers and drying oven manufacturer of the gas fraction. Gas hot water boiler output both hot water at different temperatures and indoor heating can do in one machine.
Several characteristics of a gas steam boilers and drying oven manufacturer, steam boiler burner gas supplied by well-known manufacturers in the world, according to the automatic combustion controller instructions, stop, 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 / T619-2002 "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.
Central heating hot water boilers for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.
