Reciprocating grate is a mechanical device that realizes fuel transportation and combustion through the alternating movement of grate plates. It is mainly composed of fixed grate beams and movable grate beams. According to the layout method, it is divided into three types: inclined type, horizontal type and strip type. Among them, the horizontal structure is widely used in small and medium-sized boilers. This equipment realizes the reciprocating motion of the grate plates through the hydraulic drive system, and is combined with the shearing device to break the fuel lumps to improve the combustion efficiency. It has the characteristics of low metal consumption and strong fuel adaptability. In the field of waste incineration, the thermal efficiency of 400t/d grade equipment can reach 80.66%, and special technical standards have been formulated for the field of industrial solid waste incineration
Products Description
As a kind of mechanical combustion equipment, reciprocating grate focuses on the field of efficient fuel conversion, especially in specific scenarios, and has irreplaceable functions. The main application directions are as follows:
1. Applicable fuel types
Treatment of inferior fuel
High ash coal/brown coal: the reciprocating movement of grate plate can break coke, peel ash shell, enhance air permeability, and significantly improve the combustion efficiency of low calorific value and high ash fuel.
Biomass fuel: such as straw, wood chips, etc., adapt to its high volatile matter and easy coking characteristics, and the raking action prevents the fuel from coking.
Urban household waste: it can be directly incinerated without pre-classification, and is compatible with complex solid waste.
2.boiler application scenarios
Small and medium-sized industrial boilers
Simple structure, low metal consumption, suitable for 10-75t/h capacity boilers, to meet the demand of district heating, plant steam.
Special industrial furnaces
Waste incinerator: the thermal efficiency of 400t/d level waste incineration equipment is up to 80.66%, and the ash and slag are fully burned.
Solid waste treatment furnace: customized for industrial waste (such as drug residue, sludge) to meet environmental emission standards.
3. environmental protection and economic needs
Low cost combustion solution
Hydraulic drive system maintenance cost is low, suitable for projects with limited budget.
Pollution reduction scenario
Double-sided ignition + fire-picking design reduces the generation of black smoke, and the effect of smoke and dust removal is better than that of simple fixed grate.
4. technical adaptation scenarios
Optimize combustion requirements
The running grate travel is adjustable (30-100mm), and the feeding frequency (1-5 times/min) can be changed to adapt to different fuel layer thickness.
Load fluctuation condition
The load regulation range is wide (30%-120%), which can adapt to the frequent changes of steam demand.
The core value of reciprocating grate lies in solving the problem of poor fuel combustion and cost control of small and medium scale combustion system, especially in the field of waste incineration, biomass energy utilization and high ash coal treatment with technical advantages.
