A hybrid or combination boiler system refers to a heating system that combines two different types of heating technologies or fuels to optimize efficiency, performance, and cost-effectiveness. This system typically involves the integration of a traditional gas or oil boiler with a renewable energy source, such as a solar thermal system, a biomass boiler, or a heat pump. The idea is to harness the strengths of both systems to achieve greater energy efficiency and environmental sustainability.

There are several ways to estimate the thermal efficiency of gas-fired boilers:
1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.
2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
According to its structural characteristics, double-drum water-tube boiler can be divided into D-shaped and KB-shaped. Here, ZOZEN Boiler will explain the structural principles and characteristics of two kinds of double longitudinal boiler tubes.
D-shaped double longitudinal drum water tube boiler structure
D-shaped double-longitudinal-drum water-tube boiler structure has a furnace on the right side and a convection tube bundle on the left side; The movable supports in the middle and both ends...
Shell boiler (also is known as the fire tube boiler) and water tube boiler are two main types of industrial boilers. There are many differences between shell boiler and water tube boiler, and they have their own advantages and disadvantages. Users can choose shell boiler and water tube boiler according to specific application conditions. This article will analyze the difference between shell boiler and water-tube boiler, and help you make correct purchasing decisions.

It depends on the system of the gas boiler, the boiler water temperature at 60-90, 90-150 and 70-130 can achieve better energy-saving effect.
Energy-saving devices such as condensers are added to ZOZEN gas-fired hot water boiler. The waste heat is used to increase the water temperature of the gas-fired boiler. The rated inlet temperature is 70℃, and the exhaust gas temperature is reduced, so that the thermal efficiency of the boiler is increased to over 98%.
The boiler in the bathhouse provides hot water for bathing and heating, and it is an essential product in bathhouses. Generally, it is hot water boiler. With the elimination and banning of coal-fired boilers, many users choose energy-saving and environment-friendly gas-fired boilers. Then how much is a suitable gas-fired boiler?
First of all, we have to determine the boiler plan. Bathhouses mainly need to supply hot water and winter heating all the year round. There are two main options: one se...
Raw water: refers to water that has not been disinfected and filtered, such as river water, stream water, well water, reservoir water, etc.
Feed water: refers to the chemical water delivered from deaerator to boiler by feed pump.
Make-up water: Make-up water for boiler is to make up the lost part or externally supplied part after completing a steam-water cycle, so that the boiler can always operate at a safe water level.
Recycling condensing water: When the heat energy of steam or hot water i...
A cornertube boiler is a type of natural circulation water-tube boiler which differentiates itself from other water tube boilers by its characteristic water-steam cycle and a pre-separation of heated steam from the steam-water mixture occurs outside the drum and the unheated downcomers.
