Evaporation tube bundle and water cooling tube panel are two important heating surfaces of the boiler, which are all arranged inside the boiler, so it is not easy to see them intuitively.
Boiler evaporation tube bundle
Evaporation tube bundle mainly absorbs convection heat transfer in small and medium-sized boilers. Generally, it is a bundle of dense staggered piping systems consisting of ascending pipes and descending pipes that connect the upper and lower drums. The heat load of the ...
Boiler is a kind of common heating equipment, and its temperature is an important performance parameter.
There is no relevant standard for boiler temperature classification.
As a matter of fact, domestic power boilers are generally classified according to pressure, but not according to boiler temperature grade, but the temperatures corresponding to different pressures are different. The specific correspondence is as follows:
Low pressure boiler P≤2.45MPa, the saturation temperature is not ...
Thermal oil heater is a boiler that uses heat conduction oil as heat medium to transfer heat. What is the meaning of low nitrogen thermal oil heater in Shanxi? We can understand it by disassembling the key words into Shanxi, low nitrogen and thermal oil heater. Shanxi refers to the region of Shanxi Province; Low nitrogen refers to the low emission of nitrogen oxides from the boiler, generally referring to 30mg/Nm³ and 50mg/ Nm³; Thermal oil heater is a common type of boiler. Therefore,...
Why are there CO boilers? As the leading enterprise of industrial boilers, ZOZEN Boiler not only provides users with high-quality products, but also provides users with perfect installation services. Here are the main steps of hot water boiler pipeline installation: 1. The installation of water supply pipeline should start from the equipment connection end, extend outward based on the pipeline interface on the equipment, and pay attention to the installation under the heating pipe. Set the highe...
Heating boiler is a kind of thermal equipment that uses the heat energy released after fuel combustion to transfer to the water in the container, so that the water can reach the required temperature or steam at a certain pressure. Boiler is widely used in central heating, school hotels and enterprises, and its performance determines whether people can spend the winter warm, comfortable and economically. When users choose industrial heating boiler companies, they often comprehensively examine the...
Boiler heat supply refers to the continuous heat production per unit time when the rated parameters, rated flow, designed fuel and efficiency are guaranteed. There are many ways to express the boiler heat supply, and there are certain conversion standards.
Conversion between heat supply units: 1t/h = 0.7mw = 600,000 kcal/h =720KW
According to the conversion standard, a 5-ton boiler is also a 3.5MW boiler. Therefore, for the users who need 3 million kcal boilers, we recommend WN...
Two characteristics of environment-friendly thermal oil heater
1. Ultra-low nitrogen emission
Countries or regions, according to the actual environmental situation, have formulated the corresponding emission standards of boiler air pollutants, which have clear requirements for nitrogen oxides, sulfur dioxide, dust and flue gas blackness.
As a professional manufacturer of environment-friendly thermal oil heater, ZOZEN deeply studies low-nitrogen combustion technology, and its environment-frien...
The boiler economizer is a device installed at the lower part of the flue at the tail of the boiler to recover the waste heat of the exhaust gas. It absorbs the heat of the high-temperature flue gas to heat the boiler feed water, reduces the temperature of the exhaust gas of the boiler, saves energy and improves the thermal efficiency of the boiler. Therefore, when using boilers, it is very important to master the correct treatment method of boiler economizer tube burst.
