what is boiler chain grate?
A boiler chain grate is a moving, conveyor-belt-like metal floor inside an industrial furnace that feeds solid fuel, moves it through active combustion zones, and drops out the remaining ash. It is widely used for burning coal and biomass pellets in factories and power plants. How It WorksFuel feed: Solid fuel drops from a storage hopper onto the front of the moving metal chain link belt.Combustion zones: The continuous loop carries the fuel slowly past a hot brick arch that dries and ignites it.Air control: Fans blow air up through tiny gaps in the moving metal grate bars to feed oxygen to..
Technical Analysis of Active and Driven Grate Bars for Travelling Chain Grate
The travelling chain grate is the core fuel conveying and combustion equipment for medium and small coal-fired and biomass stoker boilers. The complete grate system is assembled by active grate bars (drive bars) and driven grate bars (follower bars) arranged alternately in series. The two types of bars differ completely in structure, stress principle and operational functions. With clear division of labor and coordinated operation, they jointly realize the full-process functions of fuel conveying, ventilation combustion, sealing, anti-leakage and slag removal. Their material selection, m..

Detailed Performance of Silicon-5 Heat-Resistant Cast Iron (RTSi5) Grate Bars Under High-Temperature Conditions
1. Basic Material Parameters Grade: RTSi5, national standard heat-resistant cast iron; silicon content ranges from 4.5% to 5.5%, with ferrite as the main matrix structure. Designed long-term safe operating temperature: 750℃ ~ 850℃; short-term peak temperature tolerance: within 880℃. 2. Comprehensive Performance Within the Optimal Temperature Range (750–850℃, Conventional Boiler Operating Conditions) This is its peak service condition: (1) High-Temperature Oxidation Resistance (Primary Core Advantage) A dense, intact silicon dioxide (SiO₂) protective film automatically forms on the heated..
What is the applicable moisture range of fuels for biomass reciprocating grates?
1. Optimal High-Efficiency Moisture Range Loose conventional biomass fuels (wood chips, chopped straw, etc.): as-received moisture content 15%~25%. This range balances drying rate, stable combustion performance and thermal efficiency, and perfectly matches the structural design of the pre-drying zone of reciprocating grates. Molded biomass pellet fuels: as-received moisture content ≤15% (ideal range: 8%~15%), delivering the most stable combustion and maximum thermal efficiency. 2. Maximum Allowable Limit (Extreme Adaptation Range) Reciprocating grates equipped with optimized drying zo..
Reciprocating Biomass Grates: Core Differences Between S-Type, Wide Flat & T-Type Grate Bars
These three most widely used reciprocating grate bars differ entirely in interlocking profile structure, air throughput, ash leakage performance, fuel stirring & pushing effect, and applicable fuels. Detailed breakdowns and selection guidelines are listed below for your presentation to overseas customers. 1. S-Type Grate Bars Structural Features Curved S-shaped surfaces on both sides interlock with adjacent pieces. When movable and fixed grate bars slide alternately, the overlapping surfaces form a continuous labyrinth seal. Advantages The lowest material leakage rate; ideal for f..
