Coal Fired Steam Boiler DZL/DZH coal steam boiler and wood pellet boiler


Brief Introduction

  The DZH/DZL Coal Fired Steam Boiler produced by the company is a single-cylinder vertical-type water-fired tube-shell boiler, and the combustion equipment is a chain grate.

   The water-cooling wall on the left and right sides of the furnace is a radiant heating surface, the two wings of the furnace are convective heating surfaces, the convection heating surface of the threaded tobacco pipe is arranged in the drum, and the front and rear arches are made of a heat-resistant concrete integrally cast enamel.

   The outside of the boiler main body is three-dimensional shield housing. Yongxing Boiler Manufacturing Co., Ltd. produces a variety of industrial boilers, such as biomass boilers, fuel gas boilers, coal-fired boilers, electric steam boilers, thermal oil furnaces, hot air boilers, organic heat carrier boilers, steam generators, etc.

   The products are sold to more than 30 provinces, cities and regions in the country and exported to Malaysia, Myanmar, Vietnam, the Philippines, Ecuador, Indonesia, Russia and other countries.


Coal Fired Steam Boiler Structural features

1. The boiler furnace is designed as a full water cooled combustion chamber. The left and right membrane walls extend all the way to the upper surface of the grate, and the water-cooled furnace is formed with the water-cooled arches before and after, which increases the radiation heating surface of the furnace and improves the working efficiency of the boiler.

2. The pipe at the bottom of the drum and the headers on both sides constitute the rear arch pipe, which successfully solved the reduction of the height of the boiler and improved the space utilization inside the boiler.

3. The whole boiler adopts low thermal inertia design. The overall efficiency of the boiler is more compact, and the heat radiation area of ​​the furnace is increased by more than 50%. At the same time, the use of the light furnace wall reduces the thermal inertia of the boiler by 70%, improves the combustion efficiency, and makes the boiler load adjustment more flexible.

4. 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.

5. 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.

6. 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.

Coal 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 step-less 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.
