How to handle the drying of the scale grate?

　　How to handle the peeling of the scale grate?

　　Reasons: 1. The chain is too loose, and some parts are stuck. 2,Scale grateCoal leakage, excessive dust leakage, excessive ash and arching between the scale grate or scale grate and sprocket. 3. The spacing of the scale grid is too small, and the bolts are too tight. After heating, the scale grid pieces expand and arch.

　　Handling methods: 1. Adjust the chain; if the chain itself is unqualified, it needs to be replaced. 2. Set up the system to eliminate coal leakage and re-leakage in a timely manner; 3. The installation of the scale furnace should not be too tight, allowing for free movement.

　　How to handle the deviation of the scale grate?

　　Reasons: 1. The front and rear axes are not parallel, and the two axes are not perpendicular toScale gratethe centerline. 2. The two discs are not parallel, not level, and not perpendicular to the two axes. 3. The lengths of each chain are inconsistent. 4. The adjustment bolts of the front two sides of the chain are inconsistent. 5. The front axle, rear axle, and bearing wear unevenly. 6. The steel frame or windbreak part at the bottom of the focus box is bent into the furnace, causing direct friction with the furnace, pushing the scale furnace to one side.

　　Handling methods: 1. Measure and adjust; 2. Replace unqualified parts; 3. Identify the reasons for the inconsistent chain lengths and replace them. 4. Adjust the nuts on the front side; 5. Repair or replace damaged bearings or front and rear axles. 6. Repair or replace the front rail.

　　How to handle the falling of scale grate pieces?

　　Reasons: 1. The geometric dimensions of the scale furnace do not meet technical requirements, and the lengths are inconsistent. 2. The length of the pitch sleeve is inconsistent; if it is too long, the spacing of the clamping plates is too large, causing the scale grid pieces to fall off—group falling off; 3. The small shafts at both ends of the scale grate wear out—; 4. The clamping plates are cracked or the holes are worn.

　　Handling methods: 1. Replace the non-compliantScale grate2. Replace with appropriate pitch sleeves; 3. Replace broken or non-compliant clamping plates.

　　The scale grate is divided into three parts: drying furnace, combustion furnace, and ash melting furnace. The segments can fully mix garbage during drop, scale grid, and garbage drop, flip, and enhance combustion. Each grate section uses longitudinal extraction reciprocating motion, which can push back some of the garbage that catches fire in the front, accelerating the drying and ignition of the newly incoming garbage. A shear knife is installed between the combustion grate and the ignition grate, which can remove blockages and enhance the full contact of garbage with air, making the combustion of garbage cleaner.

　　Designed and manufactured according to the characteristics of biomass molded fuel, a double-layer flake grate structure suitable for biomass molded fuel combustion boilers has been developed through detailed thermal calculations and processing technology, resulting in low losses from incomplete combustion of gas and solids, high combustion efficiency, and still low nitrogen oxide content in exhaust gas, meeting boiler pollutant emission standards.
