SZL Coal-Fired steam boiler with chains of double drums Introduction :
|
|
SZL
steam boiler with chains of double drums adopt longitudinal drainage
grate steam, the convection heat transfer arrangement of heating
surface, high efficiency, reasonable water system, large water
capacity, the large steam space with high-quality steam. Convection
heating surface of the largest boiler has smooth features of high
efficiency with a certain overload capability.Light chain grate together
with the variable speed belt assembly plant makes the best combustion
conditions; The adjustment means more complete combustion to achieve the
use of light chain grate mechanical stokers, and it is equipped with
drums and fun to realize mechanical ventilation.Fuel from coal scuttle
fell on the grate, grate into the furnace with the post-combustion, flue
gas through the combustion chamber after the upper arch, shed from the
combustion chamber up through the pipe smoke after the first bundle to
the front room into the smoke box, and then from the former tobacco fold
into the box after the second beam to the smoke box, pumping lead into
the fan through the flue, and chimney dust, and finally discharge to the
atmosphere. The boiler has features of high automation. It feed water
automatically. When water level is too high or too low, the alarm will
ring. Also, it has low water interlock protection. It fully realizes the
mechanical operation. Series of SZL Boiler is the horizontal dual
cylinder portrait arranged, chain grating,pipe steam and hot water
boiler designed by our technical personnel according to advanced
technology and experiences from home and abroad.The
technology,performance and environmental protective index of this series
of products reach the international advanced level,and this product
is the mainstay one in boiler industry.

Structural characteristics of:
The boiler
uses quick fitting or assembly structure.The 4-6t/h boiler is of quick
fitting pipe structure,exit shop after completely assembled;The boiler
of 6-25t/h is composed of 2 main components:The upper assembled
component is the body heat accepting part,and the lower assembled
component is of combustion equipment.The former part of the boiler body
is arranged as water cooling wall,the upper part of it is connected to
boiler cylinder,and its lower part is connected to collective chest,so
as to form a combustion room and absorb the radiated heat from the
furnace;its rear part is arranged with dense convection pipe bundle
between upper and lower boiler cylinders;the high temperature smog after
combustion shall stand for twice returning flushing transversely to the
heat accepting surfaces, and shall be introduced to coal saver singly
arranged, and flow into duster and exhausted from chimney in the end.The
20t/h assembled water pipe
boiler is composed of front furnace,rear furnace,convection pipe
bundle,coal saver and chain grating,and which are assembled in big
components respectively for delivery.

Products Advantages:
|
This series of boiler absorbs the merits from quick fitting
boiler,features compact in structure,the boiler's shop is of one storey
arranged,convenient for site installation,short in construction
period,cheap in cost,simple in operation and etc.This series of steam
boiler is suitable for industrial and living steam consumption;the
correspondent capacity hot water boiler is applied for industrial and
civil heating purpose.
