Fangkuai water wall corrosion coal fired boilers take you to know that horizontal steam boilers are usually used in a very large number of models, depending on the fuel, the working principle, and the different structures of the boiler itself, which are divided into many different types of boilers, and they are divided into many different types, depending on the fuel, the working principle, and the different structure of the boiler itself. In the case of steam boilers, there are also ordinary boilers and steam boilers, for this horizontal steam boiler, its characteristics are not the same. The boiler arch is made of refractory concrete. The rear arch is low and long, so it burns well. The two-wing flue and side wall brick are made of refractory brick. Boiler front wall, rear wall using universal refractory brick. The air distribution of the grate is reasonable, and the combustion chamber is larger. The applicability of coal is strong. Suitable for all kinds of bituminous coal or anthracite, mixed coal. It burns well. Because the high temperature flue gas first enters the settling chamber and then into the two-wing flue from both sides, and the front smoke box, so the smoke elimination and dust removal effect is good. The water circulation is simple, the compressed parts have reasonable structure and can run safely under the condition of ensuring water quality. The burning equipment is a fast-loading grate. The burning equipment is manufactured and installed in the factory and installed directly on the ground after transportation to the site. It has the advantages of reasonable structure, compact structure and low steel consumption, which makes the boiler's performance, weight and structure size obviously advanced compared with the domestic products with the same capacity. The boiler type is horizontal fast loading water Fire tube boiler, working fluid natural circulation. The boiler heat transfer system consists of a boiler drum, a left and right header, and a water wall. The heating surface is mainly composed of a furnace water wall, a part of the boiler drum and a convection tube bundle in the boiler tube.

About hot water water wall corrosion coal fired boilers including hot water boiler electric water boilers, hot water boiler fuel, gas hot water boilers and coal-fired hot water boilers, hot water boilers that produce hot water boilers, is the use of the thermal energy released from fuel combustion or other thermal energy (e.g., electrical energy, solar energy, etc.) the water was heated to a nominal temperature of a thermal device. "Special Equipment Safety Supervision Regulations" as defined in the boiler is the use of various fuels, electricity or other energy sources, the costumes, the liquid is heated to a certain parameter, and external heat output devices. Which is defined in a range equal to or greater than the volume of the pressure of the steam boiler 30L; outlet pressure is greater than or equal to 0.1MPa (gauge pressure), greater than or equal to the rated power and the pressure of the hot water boiler 0.1Mw; organic heat boiler. From "Special Equipment Safety Supervision Regulations" Uses People's Republic of China: There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can achieve the dual function of bathing and heating using inspection items include: checking in the internal boiler inspection and ready to use, furnace and flue boiler inspection accessories check check, auxiliary equipment automatic control system, check the combustion equipment, check the auxiliary heating surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling.

Features water wall corrosion coal fired boilers are widely used in petroleum, chemical, pharmaceutical, textile, light industry, building materials and so on. A low pressure, high temperature, safe, energy efficient features. Operating with complete control and monitoring of safety devices, the operating temperature can be precisely controlled. Reasonable structure, fully furnished, short installation period, easy operation and maintenance, ease of boiler arrangement. Since electric heating furnace Heat Transfer Fluid advanced explosion-proof structure, it can be used in factory area Ⅱ proof, explosion-proof grade C up to level. In recent years, due to the need for environmental protection and rising oil prices, many local governments and enterprises will be coal-water slurry fuel as a clean alternative to oil to be used. Especially in the small and medium industrial boilers. CWS boiler market development trend, there are two, one is modified in accordance with the way oil furnace coal boiler, namely the design (CWS oil boiler) on the basis of oil furnace system; one is in accordance with the bulk coal transformation of the way CWS boiler furnace, namely design (bulk coal water slurry boiler) scattered coal stove in the system. Before the existing oil-fired boilers plus pre-furnace. Advantages: high degree of automation, small volume, pleasing in appearance; disadvantages: complicated equipment, pre-furnace combustion pressure, high temperature, easy to ash fusion, pre-furnace coke, slag is very difficult, not suitable for continuous operation. The principle is the bulk coal boiler design, little change furnace, auxiliary substantially constant configuration parameters, the first half of the boiler combustion good, but the rear of the flue gas emission unreasonable, because different from the coal for coal-water slurry, coal slurry containing 34% to 38% moisture, so the contained amount of water vapor in the flue gas, so that dust desulfurizer two tails, induced draft fan and stack gray water condensation, clogging and corrosion. Excessive speed plus smoke, fine dust, very large friction, serious damage to the auxiliary equipment, continuous operation can not lead to a discharge portion, the discharge of non-compliance.
