According to the differences in fuel and structure, industrial thermal oil heaters are mainly divided into the oil/gas-fired thermal oil heater and coal/biomass-fired thermal oil heater. The basic configurations of the thermal oil boiler system generally are as follows.
The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.
Percussive sounds ("banging," "hammering," or "knocking") and vibrations in boiler drums or pipes are serious operational anomalies that demand immediate attention. At ZOZEN, we engineer our coal-fired boilers (like the SZL water-tube and DZL fire-tube series) to minimize these risks, but they can still arise due to operational or system issues. Here are the primary causes and ZOZEN's approach to mitigation:

A firetube boiler can react very quickly to load changes due to the fact that it has a large volume of stored energy in the form of hot water and steam.
After combustion, biomass-fired boiler fuel will generate energy and also produce some combustible matter in fly ash which will have bad influence on the surrounding environment. Therefore, in order to realize the goal of environmental protection, we should reduce the generation of combustible matter in fly ash in biomass-fired boiler fuel.
The thermal efficiency of an industrial boiler is a measure of how effectively the boiler converts the energy contained in the fuel into usable heat. It is typically expressed as a percentage, indicating the ratio of heat output for heating or producing steam to the energy input from the fuel consumed. This efficiency is crucial for understanding the performance of a boiler, as it directly impacts fuel consumption, operational costs, and environmental emissions.

The gas-fired boiler is operated by an advanced combustion machine, equipped with automatic gas supply and ignition combustion system, and the gaseous fuel is easy to burn. Therefore, the gas-fired boilers need not be equipped with blower and induced draft fan components.
The installation contents of boiler body pipeline are as follows:
1) Connection between water supply console and economizer header;
2) Connection between economizer and inlet pipe from economizer outlet to drum;
3) Connection between the main pipe and branch pipe of the drum drop and each lower header of the water wall;
4) Connection of steam guide pipe between each water wall header and steam drum;
5) Connection of superheated steam pipe between outlet header of low-temperature superheater...
