Advantages of Mobile Boiler Grate Products
As a core component for mobile boilers, the mobile boiler grate must meet three core requirements: mobility, adaptability, and durability. Our company's mobile boiler grates, designed for the "variable operating conditions, convenient installation, and efficient maintenance" characteristics of mobile boilers, offer six differentiated advantages:
1. Lightweight and High-Strength Design for Mobile Operations
Mobile boilers have stringent requirements for component weight and structural strength. Our mobile boiler grates utilize lightweight alloy cast steel (ZG20Cr9Ni4), reducing weight by 30% compared to traditional cast iron grates while maintaining high-temperature resistance and wear resistance. This significantly reduces the overall weight of the mobile boiler, improving the flexibility of equipment relocation and transportation, and reducing trailer transportation costs. Simultaneously, the grate frame adopts an integrated reinforced structure, increasing impact and bump resistance by 40%, adapting to frequent relocation scenarios such as road transport and temporary site installation, preventing grate deformation and component loosening caused by bumps.
II. Quick-assembly and disassembly modular structure, doubling installation efficiency
Addressing the "ready-to-use" requirement of mobile boilers, the grate adopts a weld-free modular splicing design:
The grate plates are connected to the crossbeams via quick-release clamps, allowing a single grate module to be assembled and disassembled within 30 minutes, reducing installation time by 70% compared to traditional bolt fixing methods;
Standardized connecting flanges allow for direct and quick adaptation to the mobile boiler furnace, eliminating the need for on-site secondary cutting and welding, reducing installation difficulty and labor costs;
Module dimensions can be flexibly customized according to the tonnage of the mobile boiler (0.1-10t/h), adapting to various mobile devices such as small steam boilers and hot water boilers.
III. Multi-fuel Compatible Design for Complex Fuel Scenarios
Mobile boilers are commonly used in construction sites, farms, and temporary heating applications, where fuel sources are complex. Our mobile boiler grate structure is specifically optimized for these applications:
The grate bar gap is adjustable (3-12mm). By changing the adjusting shims, it can quickly switch between various fuels such as coal, biomass pellets, waste wood, and straw, solving the problem of unstable fuel supply in mobile scenarios;
An anti-coking and slag scraping device is added, combined with the inclined grate surface (12°-15° inclination), to achieve automatic slag sliding, avoiding manual slag cleaning and improving the degree of automation.
IV. Vibration-Resistant Sealing Structure for Strong Operational Stability
Mobile boilers are prone to vibration during transportation and operation. The grate employs a double-sealing design to ensure stable operation:
The grate side seal uses wear-resistant flexible graphite sealing strips, which automatically compensate for gaps with vibration, controlling the air leakage rate to within 2%, preventing cold air from entering and affecting combustion efficiency;
A shock-absorbing buffer pad is added to the bottom of the grate to absorb the impact of vibration during operation and transportation, reducing resonance noise between the grate and the furnace, while protecting the grate plates and transmission mechanism, extending their service life.
V. Low-Power Transmission System for Reduced Operating Costs
Mobile boilers often use diesel generators or temporary on-site power supplies, making them sensitive to energy consumption. Our grate is equipped with a low-speed, high-torque variable frequency drive mechanism:
The drive motor power is reduced by 25% compared to traditional grates, and it can be adapted to 380V industrial power or 220V residential power, meeting the needs of temporary power supply scenarios; The variable frequency speed control design can adjust the grate speed in real time according to fuel combustion conditions, achieving precise air and fuel distribution, resulting in more complete fuel combustion, improving overall thermal efficiency by 8%-10%, and reducing fuel consumption. VI. Easy-to-maintain, no-major-overhaul design, reducing operation and maintenance difficulty
Considering the limited maintenance conditions in mobile scenarios, the grate adopts a front-mounted design for vulnerable parts:
Vulnerable parts such as grate plates and sealing strips are all located at the inspection port on the side of the boiler, allowing for replacement without disassembling the entire grate, and maintenance can be completed by a single person;
The transmission mechanism uses sealed bearings, which are dustproof and waterproof, adaptable to harsh outdoor environments, and can achieve 2 years of maintenance-free operation under normal working conditions;
A portable maintenance toolbox and spare parts package are provided to meet on-site emergency maintenance needs and prevent project downtime due to malfunctions.link:http://www.qyhsmachinery.com
