The capacity of a trolley furnace, also known as a pusher furnace, can vary depending on its size and design. These types of furnaces are typically used for batch processing of products in various industries such as metalworking, glass manufacturing, and ceramics production.

A trolley furnace consists of a series of trolleys or carts that move products through various heating zones inside the furnace. The number of trolleys can vary depending on the size of the furnace and the size of the products being processed. Some smaller trolley furnaces may only have one or two trolleys, while larger furnaces can have several trolleys operating simultaneously.

The capacity of a trolley furnace is typically measured in terms of the number of products or batches that can be processed at one time. For example, a small trolley furnace may have a capacity of processing 10 to 20 products per batch, while a larger furnace can handle 50 to 100 products per batch.

In terms of production volume, a trolley furnace can process hundreds to thousands of products per day depending on the size of the furnace, the speed at which the trolleys move through the heating zones, and the cycle time required for each batch of products.

The efficiency of a trolley furnace in processing multiple products simultaneously depends on several factors such as the design of the furnace, the temperature and heating profiles inside the furnace, the type of products being processed, and the control system used to monitor and regulate the heating process.

Overall, trolley furnaces are versatile and efficient equipment for batch processing of products in various industries. With the ability to handle multiple products simultaneously and process them in a controlled and efficient manner, trolley furnaces are an essential tool for many manufacturing processes.
