High Efficiency Biomass Fired Steam Boiler 2-15 Ton Rice Husk Steam Boiler

High Efficiency low Price 2-15 Ton biomass boiler and rice husk steam boiler manufacturers

Boiler design features:
1. According to the principle that the furnace heat radiation amount and temperature are proportional to the fourth power, the company optimizes the heating surface of the boiler during design, so that the total heat absorption of the wave furnace is large and has good expansion and contraction.
2. The boiler adopts an axisymmetric return structure. The high temperature flue gas collects in the front smoke box, and the temperature of the rear smoke box is very low. The boiler body is directly insulated with insulation material, which reduces maintenance costs. The integrated front smoke box is designed with double doors and is simple in structure for easy opening, operation, operation and maintenance.
3. The boiler uses aluminum silicate and centrifugal glass wool as insulation materials, which have good thermal insulation performance, light weight and convenient transportation and installation.
4. 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.
5. 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 is fully symbolized by the national standard.

The product transportation picture is list below.

 Protection measures for boiler deactivation
When the boiler is shut down for a long period of time (more than one week), the steam system must be operated hydrophobically to keep the system dry through the air. Dry air enters through the main steam valve and is discharged from the bleed and trap.

Nitrogen protection is required after the boiler is dried. Nitrogen enters the boiler system from protective valves and lines on the main steam line.
1. Shutdown protection measures for low pressure circulation system
If the low pressure air preheater and the low pressure flue gas cooler circulatory system are hydrophobic, the interior also needs to be dry. Dry air enters from the deaerator and is discharged from the bleed and trap.
2. Protection measures for the flue gas system
- When the boiler is shut down for a long time, the flue gas system must be cleaned. The flue can be cleaned with a high pressure air stream from the air preheater to ensure that the heated tube surface is dry.
- After the boiler has been out of service for more than one month, consider filling the flue with dry air to protect the heated surface.
- Protective measures for each component
When the furnace is shut down for a long time, different boiler components need different protection, movable parts should be inspected, and electronic and electric equipment should be heated and maintained frequently.
