What affects the heating capacity of vacuum hot water boiler

2014-05-16

The vacuum hot water boiler manifests its characteristics: reliable in design, steady in operation, and no requirement for supplement of heating medium water.As a new type of industrial boiler,many people do not have a good knowledge about the vacuum hot water boiler,in the following sections,the relevant engineer of Zhengzhou Boiler Co., Ltd,will introduce some factors affecting the its heating capacity.

The material of vacuum hot water boiler heat transfer tube

The heat supply of vacuum hot water boiler is mainly the output of heat,the heat transfer tube is the tube of heat output,the material of a large heat transfer coefficient means big heating capacity,therefor,the heat transfer tube material of vacuum hot water boiler generally adopts the brass or stainless steel tube of a large heat transfer coefficient.

The air volume of vacuum hot water boiler burner

Too large air volume contributes the increase of flue gas volume,part of the effective thermal energy is wasted,which reduces the thermal efficiency of vacuum hot water boiler,too small air volume will lead to the incomplete combustion,which also reduce the thermal efficiency,the air volume of burner is generally adjusted in the debugging of vacuum hot water boiler.

The water flow rate and water quality of vacuum hot water boiler

The water quality is directly related to scale formation in the boiler,larger scaling factor means poorer heat transfer performance,the heating capacity will reduce.When other condition is constant,the water flow rate changes in a certain range,the reduction of water flow rate leads to the reduction of tube heat emission coefficient and the reduction of thermal efficiency.

The thermal efficiency of vacuum hot water boiler manufactured by Zhengzhou Boiler Co., Ltd,can reach 92%,it means a high heating capacity,vacuum hot water boiler is leading a new trend of civil heating system,if you want to know more about it,you can browse its webpage or consult us!

Steam Boiler Used in Paper Industry and Paper Mill

2026-07-30

Paper mill need stable and high-quality steam boiler to support whole production line. XHJ boiler has rich experience in paper industry supporting, very suitable for all kinds of paper mill production scenarios. Steam Boilers in paper mill are used for process, electrical power, and economic reasons (in the Kraft process, specifically).

Fire tube steam boiler Advantage Introduction

2026-07-27

XHJ Boiler factory will introduction fire tube steam boiler advantage. Fire tube boiler may be used in steam or hot water applications. A fire-tube steam boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
