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.

When it comes to replacing water-cooled wall tubes in boilers, there are several quality requirements that need to be met. These requirements ensure the proper functioning and longevity of the boiler system.
1. Tube Material: The replacement tubes should be made of high-quality materials that are suitable for the operating conditions of the boiler. Common materials include carbon steel, alloy steel, or stainless steel, depending on factors such as temperature, pressure, and corros...
(1) The mortar in the outer brick joints of the furnace wall can be ground into powder by hand without bonding, which indicates the mortar has been dried.
(2) Use a thermometer to insert 100mm from the outer wall. When the temperature reaches 50℃, it can last for 48h, and the outer wall temperature should be uniform.
In general, gas-fired boiler uses natural gas to heat water in order to provide heat source for underfloor heating and heating radiator, while condensing gas-fired uses condensation technology to recycle the thermal energy from the exhaust gas.
In a water tube steam boiler, unlike a fire tube, water circulates inside the tubes. The heat that is generated and the combustion gases that surround the tubes heat the water that circulates inside them. Many water-tube boilers operate according to the principle of natural water circulation.
The capacity of this type of boiler can be enhanced by increasing the number of tubes in the boiler.
