During this visit, the delegation from the Indian Boiler Factory gained a detailed understanding of Dalian Huiying Machinery's range of grate products. Among the company's standout offerings is the beam-type grate, which features an oblique air-outlet design. The ventilation holes are angled at a specific degree relative to the vertical direction, enabling more effective horizontal air diffusion within the coal bed. This innovative design significantly enhances the mixing efficiency between coal and air, while also minimizing coal spillage. Additionally, the reciprocating grate is specifically engineered for biomass boilers and waste incineration systems. By utilizing the back-and-forth motion of movable grate bars against fixed ones, the fuel is continuously tumbled and mixed, making it highly adaptable to fuels of varying quality and ensuring exceptionally high combustion efficiency. Lastly, the scale-type grate, with its unique overlapping design, effectively reduces coal leakage and delivers smooth, dependable operational performance. As a result, it has become a popular choice for a wide range of industrial boilers.
