Heavy fuel coal boilers with trade assurance

Product Description

Heavy fuel coal boilers  adopts compact structure and it also has advantages: simple installation, low initial investment, safe and reliable operation, energy conservation, environmental protection, and low water quality requirement.

Heavy fuel coal boilers  Application:

Heavy fuel coal boilers on textile industry is ideal thermal equipment for the industrial and aac plant because it has advantages as follows: high automatic level, high thermal efficiency, equipped with dust removal equipment, less pollution of the environment.

Heavy fuel coal boilers  Structure:

Heavy fuel coal boilers with combustion equipment was chain grate. Main engine is single drum longitudinal arrangement and inside of drum is a single-pass thread smoke tube. The left and right sides of the hearth is equipped with bare water wall tube, part of riser pipe forms the furnace top, and refractory brick Hanging at the bottom of the drum doesn't accept high temperature flame radiation. Drum on both sides of the lower part has two symmetrical convective pass, and water wall cured tube is assembled at 750 mm from the center line of the drum, so as to avoid tearing weld joint.

Heavy fuel coal boilers  Advantages:

DZL two wings flue series boiler is small size but output is big. And pressure rises faster with higher thermal efficiency, which is domestic initiative. And the boilers are the national mechanical and electrical energy-saving products with national patent.

1. New furnace structure avoids to produce bulge defects which happens because of direct heating the bottom of the drum.

2. Avoid flue tube plate crack

3. New arch design for inferior coal combustion and coal adaptability

4. Independent adjustable wind chamber under the fire grate, and wind comes from two sides. Ventilated section ratio reaches 100% , and can be adjusted flexibly and air flows evenly.

5. Push-pull type damper ash removal device effectively prevents deformation of the secondary combustion and grate air leakage.
