Characteristics of SHL Boiler Products
The SHL series of packaged boilers are double-drum, horizontally-placed, natural circulation, coal-fired water tube boilers. The horizontally placed upper and lower drums, together with the water wall tubes, form a vertical well-type furnace, which, with the convection tube bundle manifolds, etc., constitutes the boiler body. An economizer and air preheater are located at the rear; a superheater can be installed at the furnace outlet as needed by the user. The combustion equipment is a chain grate stoker with stepless speed control. It is packaged for shipment and assembled and bricked on-site. The flue gas flow is multi-pass.
SHL Boiler
This type of boiler has the following characteristics: large boiler water capacity, strong ability to adapt to load changes, fast heating, high thermal efficiency, small footprint; the grate uses a scale-type non-coal-leaking grate, greatly improving operational reliability. Wide range of applicable coal types; the front and rear furnace arches can be cast, with good sealing performance, improved ignition conditions, environmentally friendly and energy-saving, strong combustion; high degree of automation, stable operation, safe and reliable, long service life. The boiler is widely used in industrial and mining enterprises and in the field of centralized heating for people's lives.
The SHL boiler is a large-capacity, new type of packaged coal-fired water tube steam/hot water boiler, jointly developed by our company, after thorough research, in accordance with national energy policies and the requirements of centralized heating in northern China, and relevant research institutions. This type of boiler has high efficiency, sufficient output, good load adaptability, a relatively compact overall structure, an independent wind chamber, two-sided air intake, easy-to-control combustion, uses reasonable front and rear arch coordination, strong coal adaptability, and is equipped with over-temperature, over-pressure alarm systems and various interlocks and automatic controls, resulting in a high degree of automation in operation.
Structural Overview
