gypsum frying boiler-ebullience calciner

The reason condensing gas gypsum frying boiler-ebullience calciner fouling fouling What is the boiler is condensing gas boiler maintenance and repair should focus on issues, not only because fouling threat to the safe operation of the boiler, but also greatly increase the cost of maintenance and repair boilers, boiler shortening life. For boiler fouling problems, we should be in-depth analysis of its causes, promptly take effective preventive measures to provide effective protection for the safety, energy conservation, economic operation of the boiler. (1) a carbonate, sulfate scale carbonates, sulfates reasons of scale formation due to condensation gas boiler is the presence of calcium, magnesium, carbonates, sulfates, etc. to the solubility in water decreases with increasing temperature, to a certain extent will precipitate scale. Carbonate scale, is generally formed in the heated places less intense; sulfate scale precipitation is generally at a high temperature, often occurs in the heating surface heated relatively strong, and it is in the waterwall tubes of the boiler convective tube bank common. (2) Chemical composition of silicate scale mainly aluminum silicate scale, iron silicate compound, the chemical structure is more complex, this scale hardest texture, and very poor thermal conductivity, so the maximum harm, in general forming a high thermal condensing gas boiler load tubes. (3) the main component is iron scale iron oxide scale iron compound, condensing gas boiler in normal operation, the oxygen content of the water is very low, oxygen does not cause corrosion of the boiler. However, if the increase in dissolved oxygen, can lead to corrosion of metal surface oxide, iron oxide generated in the boiler product was dissolved in water, and at high temperature, the iron oxide scale formed gradually. For scaling condensing gas boiler safe and economic operation of harm it is very large, because it's hidden features, easily overlooked, but the boiler accidents caused due to scale accounts for a large proportion. Only by understanding the reasons for fouling produced, find a solution, by taking appropriate measures to avoid fouling, in order to ensure that the boiler safe fundamentally, run the economy.

When the gas steam gypsum frying boiler-ebullience calciner capacity is not the same, this case is more obvious, the improved system in each boiler has its own main steam pressure regulator, the regulator proportional regulator. Proportional band may be set according to the load capacity of each boiler, without affecting each other. Fuel conditioning subsystem original system primary circuit is no differential system, fuel system, improved conditioning subsystem of the primary circuit is a differential system, when the pressure is not within the competence of the nominal range, by varying the pressure of the boilers given value (corresponding to turbine adjustment position for changing the system synchronizer) to maintain the pressure in charge.

A small category 1 gas gypsum frying boiler-ebullience calciner, soft drinks dual small boilers: Rated evaporation does not exceed 0.5 t / h, rated steam pressure not more than 0.04 MPa; 2, a small hot water boiler: rated does not exceed 0.1 MPa water pressure, water pressurized hot water boiler; 3, small steam boiler: water no more than 50 liters capacity, rated steam pressure does not exceed 0.7MPa; 4, small pressure boiler aluminum: aluminum bulk material selection, not the rated steam pressure outlet than 0.04 MPa and not more than 0.2 rated evaporation t / h.

Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing steam gypsum frying boiler-ebullience calciner fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.
