The term "wet back" refers to a type of steam boiler design where the combustion chamber is surrounded by water on all sides. In a wet back boiler, the combustion gases travel through the furnace and into the smoke tubes, which are immersed in water. The heat from the combustion gases is transferred to the water, which is then converted into steam.
The term "wet back" is used to distinguish this type of boiler from a "dry back" boiler, where the rear of the combustion chamber is exposed...
A water and fire tube boiler is a type of boiler commonly used in various industries to generate steam and hot water. This type of boiler combines the features of both water tube and fire tube boilers to achieve high efficiency and versatility.
In a water and fire tube boiler, the combustion gases flow inside the tubes and transfer heat to the water surrounding the tubes. The tubes are arranged in a cylindrical shape with water surrounding them. The heat generated by the combustion proc...
In China, Class D boilers refer to steam boilers with a rated working pressure of 1.0 MPa and a rated evaporation capacity of 2 tons/hour or less. These boilers are typically used in small to medium-sized industrial facilities, such as food processing plants, chemical plants, and textile mills.
Class D boilers are subject to certain safety and performance requirements, including compliance with national and industry standards for design, manufacturing, and operation. These standards are...
When it comes to the price of heating boilers, it's important to remember that there are a lot of factors that can influence the cost, including the size and type of boiler, the brand, and the specific features and capabilities of the unit. As such, it can be difficult to make a direct comparison of prices between different brands or suppliers.
That being said, if you're looking for a high-quality heating boiler at an affordable price, consider checking out ZOZEN. As a leading manufactu...
The biomass pellet fuel can be used in general boilers. Whether it is more cost-effective than burning coal depends on factors such as the local availability and price of the fuels, as well as the efficiency of the boiler being used. In general, biomass pellet fuel can be more cost-effective than coal in terms of long-term sustainability and environmental impact. However, it may require specific equipment and infrastructure for handling and storage, so it is important to carefully evaluate the s...
Carbon buildup, also known as fouling, is a common problem in gas boilers that can lead to reduced efficiency and increased operating costs. There are several reasons why carbon buildup may occur in gas boilers, including:
1. Incomplete combustion: Incomplete combustion of the fuel can result in the production of soot and other carbon deposits. This can occur if the air-fuel ratio is not properly adjusted or if the burner is not functioning correctly.
2. Low-quality fuel: Low-quality fuel, suc...
The flue gas chamber, also known as the combustion chamber or firebox, is an essential component of an industrial boiler. Its primary function is to provide a space where fuel is burned, and heat is generated.
During the combustion process, fuel is burned in the flue gas chamber, producing high-temperature flue gases and heat. The heat is then transferred to the water or steam in the boiler tubes, generating steam or hot water for industrial processes or heating applications.
The flue gas cham...
Excess air ratio is a term used to describe the amount of air supplied to the combustion process in a boiler compared to the theoretical amount required for complete combustion. It is defined as the ratio of the actual amount of air supplied to the combustion process to the amount of air required for stoichiometric combustion.
In an industrial boiler, excess air is supplied to ensure that all of the fuel is burned completely and efficiently. The excess air ratio is usually expressed as a percen...
