Horizontal and low pressure SZL double-drum coal/biomass/wood chips steam boiler for garment and laundry

Features
1. Original mode water wall structure. Compared with the traditional structure, this structure has the characteristics of large heat transfer area, good conduction effect, low heat loss, good air tightness, no deformation of the furnace wall, and no ash leakage.

2. Extended grate design. The front and rear shafts of the grate are lengthened, so that the fuel can be more fully burned, and the effective area of ​​the grate is increased, and the boiler has a strong overload operation capability.

3. Strong adjustment performance. The boiler adopts segmental air supply and has good sealing performance, which can effectively control the air supply volume in each combustion stage and achieve the best adjustment of combustion effect.

4. High thermal efficiency. The company uses a tube wall and a cast iron economizer to further reduce the temperature of the exhaust and improve the efficiency of heat utilization.

5. The overall assembly and delivery of the factory saves the user's installation time, reduces the installation cost of the user, and improves the efficiency of the boiler.

6. The boiler adopts aluminum silicate and centrifugal glass wool as insulation materials, which have good heat preservation performance, light weight and convenient transportation and installation.

7. The upper part of the boiler is equipped with a fire-catching hole device, and the lower part is provided with a cleaning device for easy maintenance and maintenance.

8. The manufacture and design of this series of boilers are carried out in accordance with the requirements of GB/T16508.4-2013 "Boiler Shell Boiler Part 4: Manufacturing, Inspection and Acceptance", which fully complies with the national standard.

Fault diagnosis and processing system features
1. Steam pressure over-limit protection: When the steam in the pot is over-pressure, the control system immediately enters the equipment to stop working, and the sound and light alarm is given. The screen displays “Vapor pressure is extremely high”. Until the fault is eliminated, press the reset button to cancel the alarm state.

2. Water shortage protection: When the boiler has a low water level failure due to pump failure or other reasons, the control system immediately turns off the burner power supply, enters the interlocking state, sound and light alarm until the fault is eliminated, and then press the reset button to cancel the alarm state.

3). Boiler water level over-limit protection: When the water level is higher than the upper limit warning water level, the sound and light alarm. Prompt "the water level in the pot is too high", the display prompts drainage, and the pump starts to drain. The fault is automatically restored after the fault is eliminated, and the pump stops working.
