A New Design and Development of vertical Bent Water-Tube Boiler with Double-Deck Grates

Small capacity low pressure boilers are vast in number and widely used byvarious kinds of consumers. Improvement of boiler design and its combustionmethod in order to conserve fuel and protect environment is, therefore, of utmostimportance. This paper introduces a new design and development of a verticalbent water-tube boilor with double-deck grates. To overcome the serious problemsof existing small boilers with regard to their low combustion efficiency and highenvironmental pollution, the author has taken some new and efficient technicalmeasures in designing the structure of the boiler, arranging its heating surfacesand choosing its modes of combustion and ventilation. Experimental results and more than two years actual firing indicate that theperformance of the new boiler has attained a high technical level according toChinese standards of energy conservation and environmental protection. This boileris also easy and safe to operate, adaptable to many kinds of coal and has beenrecommended as a rational replacement of the existing old type of boilers ofsimilar capacities. This new boiler has been widely installed in Jiang Su, An Hwei and Zhe Jiangprovinces and Shanghai city for industrial and domestic uses and has shownremarkable economic effects.
