Because coal fuel is expensive and coal combustion can cause serious environmental pollution, it is necessary to transform the coal-fired boiler into gas-fired boiler. However, the reconstruction of coal-fired boiler is not a small project. Only pay close attention to every phase of the reconstruction process can avoid failure.
Heating surface is one criterion used when comparing boilers. Boilers with higher heating surface per boiler horsepower tend to be more efficient. Traditional packaged boilers are offered with 5 square feet of heating surface per boiler horsepower as an optimum design for peak efficiency, but new design breakthroughs allow ZOZEN boilers to have increased efficiency using more effective heating surface and reducing the size of the footprint.
The heating load of an industrial boiler refers to the amount of energy required to generate a certain amount of heat in a specific period, usually measured in British Thermal Units (BTUs) per hour, kilowatts (kW), or megawatts (MW). Essentially, it's the amount of energy needed to heat the water or generate steam in the boiler for industrial processes or heating purposes.
Understanding the heating load is crucial for several reasons:

Introduction
The operation of thermal fluid systems, commonly found in various industrial processes, inherently involves several risks due to the high temperatures and potentially hazardous nature of the heat transfer fluids. Ensuring the safety of these systems is paramount not only for the protection of personnel but also for the efficient and uninterrupted operation of the plant. This article outlines key strategies to reduce hazards and enhance safety in thermal fluid systems.

Thermal fluid degradation or “burn-up” in a thermal fluid heater can be a significant issue that leads to the loss of fluid properties, system inefficiency, and potential equipment damage. Here are the common reasons why thermal heating fluid may degrade or burn up in your thermal fluid heater:
1. Overheating:
Exceeding the thermal fluid’s maximum recommended operating temperature can lead to ‘cracking’ or breaking down of the fluid. This may produce low molecular...
The primary air fan of the boiler consists of motor, impeller, casing, air inlet box, current collector, base, regulating control system, etc.
The working process of the primary air fan: Take the medium-speed coal mill and direct-fired pulverizing system as examples, the atmosphere enters the primary air fan and is divided into two paths after being boosted by the primary air fan. One path of the atmosphere enters the primary airpipe in front of the coal mill. The other path enters the air preh...
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...
Industrial food boilers generate steam or hot water to process, cook, or sanitize food products including meat, fruits, and vegetables. Nearly every aspect of our food supply chain to grocery stores and restaurants involves steam or hot water produced by a boiler in one way or another.
