Automatic Coal Fired Hot Water Boiler Biomass Fired Steam Boiler Precise PLC Control
Biomass Fired Steam Boiler Design Features
1. The front and rear arches of the boiler adopt the "warm arch"
structure. The arching of the arches not only increases the
structural strength, but also stabilizes the temperature of the
steam in the furnace arch.
2. The boiler adopts the independent air chamber structure with
double-side air inlet, which can flexibly adjust the air volume and
the wind pressure of each air chamber to effectively ensure the
combustion effect of the fuel.
3. The boiler adopts push-pull gate ash cleaning device. The ram
material is heat-resistant cast iron, which effectively prevents
secondary combustion deformation and grate leakage.
4. The rear axle of the boiler grate is covered by a roller bearing
structure, which avoids the problem of insufficient bearing
capacity of the conventional sliding bearing.
5. The lower rail of the grate adopts the light rail “work” steel,
which is wear-resistant and not easily deformed, which can greatly
improve the reliability of the grate work.
6. The boiler is equipped with a grate, which is 500-1000mm longer
than other manufacturers. This design prolongs the burning time of
the fuel, reduces the carbon content of the slag, and improves the
thermal efficiency of the boiler.
7. The furnace wall of the boiler uses light insulation material.
This structural design reduces the heat absorption of the furnace
wall and reduces the thermal inertia of the boiler, which makes the
furnace temperature rise very fast.
Biomass Fired Steam Boiler Control system configuration instructions
Taking into account the different needs of users, the boiler's
electrical control system provides both basic and standard options
for users to choose when it is safe and convenient.
1. Basic.
The basic power control system includes start-up,
notification, and interlock control of all auxiliary motors, and
manual control mode is configured. Users can switch control modes
according to their needs. Key parameters such as drum pressure,
boiler water level and exhaust temperature can be displayed on the
human-computer interaction interface, which is convenient for users
to monitor the operation of the boiler at any time. The adjustment
system includes functions such as boiler water inlet and return
adjustment, remote control of the draft fan damper, and stepless
adjustment of the grate motor.
In addition, according to the relevant technical requirements in
the "Steam Boiler Safety Technical Supervision Regulations", the
automatic alarm function is also set in the control system,
including ultra-low water level alarm protection and steam
over-pressure alarm protection.
2. Standard type.
In addition to the above basic functions, the standard type
control system also carries out related configuration according to
the detection and monitoring requirements in JB/T10094-2002
"General Technical Conditions for Industrial Boilers", making the
detection and monitoring functions more comprehensive.
Normally the factory configuration is a basic control system.
Standard configuration or other special requirements configuration
requires user customization.
