Reciprocating vs Chain Grate: Performance on Data

In the boiler combustion equipment market, reciprocating grates and chain grates are the two mainstream products. Through long-term practice and data accumulation, our partner factory clearly demonstrates the performance advantages of reciprocating grates on several key indicators, making them a preferred choice for many customers.

On fuel adaptability, the reciprocating grate has significant advantages. Data show that reciprocating grates efficiently burn poor-quality coal with moisture ≤ 40% and ash ≤ 30%, whereas chain grates usually see combustion efficiency drop by 15%-20% on such fuel. This is thanks to the automatic poking function: the reciprocating motion of the moving grate constantly turns and loosens the coal layer, avoiding clinkering and “fire holes”, while chain grates require manual poking, which increases labor and lowers boiler efficiency when the furnace door is opened.

On economy and energy consumption, the reciprocating grate also performs well. Its metal consumption is lower than that of a chain grate…
