High-performance durable industry coal fired boiler and multi-fuel steam boiler prices with low pressure
Design Features
1. The boiler body adopts a membrane type water wall completely sealed structure. The boiler's sealing performance is greatly improved, the heat loss is reduced, the boiler thermal efficiency is further improved, and the working environment of the boiler room is improved.
2. The grate adopts the contact type lower sealing structure to solve the uneven burning of fuel caused by grate and air leakage.
3. 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.
4. 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.
5. 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.
6. 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.
Control system configuration instructions
The company offers two basic and standard control options for users to choose from.
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. 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 control system can also be customized according to user requirements.
The control system defaults to the basic type without special instructions from the user. After the user puts forward special control requirements, after the two parties communicate, if there is no technical bottleneck, the standard boiler control system can be produced.
