Premium Chain-Belt Traveling Grate from Dalian Sunshine Grate Factory | Cost-Effective Core Boiler Combustion Solution

By Dalian Sunshine Boiler Auxiliary Equipment Co., Ltd., Dalian, China

Nestled in Dalian, the renowned coastal industrial hub of Northeast China, Dalian Sunshine Grate Factory has focused on R&D and customized manufacturing of industrial boiler chain-belt traveling grate for over two decades, emerging as a trusted Chinese supplier certified with ISO9001 and CE, serving global clients across papermaking, food processing, chemical, textile and central heating sectors worldwide. Our flagship Chain-Belt Type Traveling Grate (Chain Belt Grate Stoker) is engineered as the optimal core combustion component for 0.5t/h~220t/h industrial steam boilers and 0.7MW~84MW hot water boilers, balancing stable continuous operation, low maintenance cost and outstanding fuel combustion efficiency.

Innovative Structural Design Reduces Downtime & Maintenance Cost

Different from conventional chain-belt grate with complicated disassembly structure, Sunshine’s upgraded hanging-type grate segment structure connects grate pieces with round steel tie rods into an integrated wide chain belt, enabling single-piece grate replacement without full boiler shutdown; component replacement time is cut down to only 1/3 of traditional counterparts, greatly slashing factory halt loss from routine overhaul. Three customized chain joint specifications are available to match different boiler tonnages: rolling-type & friction-type for small-medium capacity boilers, and optimized beam-separated chain joint for large-size industrial boilers. The rolling chain unit adopts high-precision ball bearing drive, lowering friction coefficient to 0.02 and cutting driving motor power consumption by 12% versus ordinary products; the split beam design separates thermal load and mechanical load, making heat-bearing grate pieces free from pulling stress and extending average service life from 3 years (industry average) to over 5 years.

Optimized sectional air distribution and precise coal gate adjustment system control coal bed thickness within ±5mm tolerance, realizing full staged combustion of coal, biomass pellet, wood chip and agricultural waste fuels. With customized sealing craftsmanship, our grate cuts air leakage rate by 40% below national industrial standard, minimizing incomplete combustion loss and lowering furnace slag carbon content below 1.5% for remarkable fuel saving. High-chromium heat-resistant cast steel for core grate plates guarantees continuous stable running over 8000 working hours without thermal crack or deformation even under long-term high-temperature furnace environment.
