Introduction

Wuxi Xi'neng Boiler designed and produced this Coal fired steam boiler, coal-fired water pipe steam boiler according to the characteristics of the fuel. This boiler is characterized by the ability to adjust the combustion surface, furnace structure and heating surface material to adapt to various coal qualities.However, the composition of coal is relatively complicated. The boiler industry usually classifies the content of dry ash-free volatiles of fuel as the main basis, which can be roughly divided into: anthracite, lean coal, bituminous coal, lignite and so on.

Structure Characteristics
1). 2000-4000kg/hr boiler adopt the fast assembly package structure, all parts are in whole assembly then leave factory. More than 6000kg/hr boiler is consisted of up and down big parts. The upper is connected with drum, the down part is connected with header. It formed combustion chamber, to absorb the furnace radiation heat, their back end arrange between the upper and lower drum with the intensive convection tube bundle. After burning, high temperature flue gas will scour the convection heating surface by two return lateral erosion, then reach the economizer, finally enter the dust remover and discharged by chimney.
2). More than 20000 kg/hr assembly water tube boiler is made of the front furnace, back furnace, convection bank, economizer and chain grate, and assembly to be whole set the leave factory.
3). The boiler absorb the advantage of the fast assembly, compact structure, the boiler room is the single layer layout, convenient installation on site, short period, low cost, easy operation etc.
4). This series steam boiler is widely used in industry and life which need steam, the relevant capacity hot water boiler is widely used in industry and heating for civil use.
