Components
A heating boiler system consists of the boiler body, heating elements, a power distribution cabinet, and a computerized controller; auxiliary equipment includes circulation pumps, chimneys, and similar components.
Classification
1. By Fuel Type: Classified into electric heating boilers, oil-fired heating boilers (using diesel, kerosene, heavy oil, etc.), gas-fired heating boilers (using natural gas, LPG, city gas, biogas, etc.), coal-fired heating boilers, and others.
2. By Heating Medium: Classified into hot water boilers and hot air furnaces.
3. By Structural Design: Classified into vertical heating boilers and horizontal heating boilers.
Selection
1. First, determine the fuel type for the boiler you wish to select-whether it is an electric boiler, an oil-fired boiler, or a gas-fired boiler.
2. Inform the manufacturer of the intended application: is it for office heating, residential heating, or bathhouse heating?
3. Provide the manufacturer with details regarding the room ceiling height, the total heating area, and the thermal insulation performance of the building.
4. Once the manufacturer recommends a specific boiler model, request the relevant technical specifications to calculate estimated heating costs and other factors.
Maintenance Methods
1. Wet Maintenance Method
First, descale and clean the interior of the boiler drum. Then, fill the boiler with fresh softened water. Simultaneously, place quicklime inside the furnace chamber and securely close all boiler doors. Note: The quicklime must not come into direct contact with the boiler body.
2. Dry Maintenance Method
When shutting down the boiler, drain the water completely. Remove any scale or deposits from the interior of the boiler drum and rinse it thoroughly. Dry the furnace chamber using a gentle heat source (a small fire). Next, place trays containing lumps of quicklime (sized 20–30 mm) inside the furnace chamber, ensuring that the quicklime does not come into contact with any metal surfaces. A suitable ratio is 8 kilograms of quicklime per cubic meter of boiler volume. Once placed, securely close all boiler doors. Inspect the quicklime every three months; if it has crumbled into a powder, it must be replaced.
