Coal Fired Steam Boilers Manufacturing

The coal fired boiler is provided with pressure gauge, safety valve and water level gauge in the furnace body. The pressure gauge shows the boiler pressure and the user knows it well. When the boiler reaches a certain pressure, the safety valve automatically opens, deflates pressure, and ensures safe and reliable operation of the coal fired steam boilers.

The coal fired boiler adopts a three – return water – fire tube structure. Both sides of the furnace filled with light pipe water wall pipe, design reasonable and compact structure. Large heating area, long flue gas flow, good heat transfer effect, low exhaust temperature. So high thermal efficiency, low operating cost, more economical to use. Equipped with high quality instrument valves and other safety accessories, complete set of equipment safety and durability, users satisfied. Users can choose to install boiler water softening device, add water treatment, less bile fouling, boiler use safety and energy saving.

The coal fired steam boilers adopts quick installation and is easy to install. This series of industrial boiler structure is compact and reasonable, convenient for hoisting and transportation. Widely used in hospitals, schools, textile factories, clothing factories, clothing supermarkets, clothing factories, dry cleaners, restaurants, hotels, canteries, food factories, beverage factories, soy products factories, meat products factories, canning plants, wine factories, pharmaceutical factories, packaging factories, building materials factories, coating factories, beauty parlors, bath centers, saunas, steam rooms and other places.

This series of industrial boilers are mainly composed of pulverized coal preparation system, burner, heating surface, air preheater and other main parts. The heating surface is divided into evaporative heating surface and superheated heating surface. Modern large and medium-sized boilers are composed of water cooling wall, from which water cooling wall (namely heating surface) absorbs radiant heat in the furnace to make water evaporate into saturated steam. In order to increase the radiation heating surface without increasing the furnace volume, large boilers can adopt double-exposure water-cooled wall. The heating surface can be divided into the screen superheater heating surface arranged in the upper part of the furnace and the convection superheater heating surface arranged in the convection flue. The former absorbs radiant heat in the furnace; The latter absorbs convective heat.

Coal boiler maintenance can be divided into dry maintenance and wet maintenance of two kinds, dry maintenance is to drain the water inside the furnace, put lime or silica gel inside the pot desiccant, and then sealed, but more trouble is to open regularly to see whether the lime is dry, silicone has no color change. Wet maintenance is filled with water in the boiler, add maintenance agents in the water, and then the boiler is sealed, as long as the maintenance agent concentration is sufficient, can ensure that the boiler is not scale, corrosion. The detection method is relatively simple, measuring the PH value of the furnace water can be. And the cost of wet maintenance may be lower than that of dry maintenance.
