Big wind bin, small wind bucket crossbeam grate - Yongning Machinery Factory patent research and dev

Large wind bin, small wind bucket crossbeam grate - to solve the uneven distribution of cross beam grates - improve combustion efficiency and save coal.

The wind storehouse is larger than the air separation chamber. The volume of the wind storehouse is 100 cubic meters, and the wind chamber is static pressure.

Small wind bucket - easy to adjust air. The structure and schematic diagram are shown below.

Transverse total adjustable valve A connecting rod structure is adopted to regulate the opening, intake, sealing and slag discharging of the 18 small wind hoppers.

Fine-tuning throttle  Adopt the lock nut structure to adjust the intake volume of three air doors on each small wind bucket.

Field wind pressure and air volume test

The advantages of the wind storehouse crossbeam grate (patent) are:

1. The performance of the crossbar grate (patent) of the big wind bin and small wind bucket = the performance of the patent crossbeam grate + the performance of the windy storehouse and the small wind bucket evenly distributing the air (patent).

2, the minimum combustion efficiency increased by 5%. A 100t/h boiler can save 2400 tons of coal in a heating period, which is equivalent to 1 million 200 thousand yuan.

3, reduce the resistance of the wind bin, wind bucket, air intake and throttle, and the low pressure of the blower can save energy significantly.

4. Small wind switches and air throttle are all casted with good sealing, no deformation and long service life.

5, convenient maintenance, can be carried out in the wind storehouse parts operation and maintenance.

6, but the structure is complex, the processing capacity is large, and the manufacturing and installation requirements are high.
