Water Steam Boiler

Steam Boiler Working Principle

 

A steam boiler is a thermal equipment that uses the heat energy released after fuel combustion or the waste heat from industrial production to transfer heat to the water in the container, so that the water reaches a certain pressure of steam. It is a complete body composed of "pot" (that is, the water pressure part of the boiler body), "furnace" (that is, the combustion equipment part), accessory instruments and auxiliary equipment. The boiler is carried out simultaneously in the two parts of the "pot" and the "furnace", and after the water enters the boiler, the absorbed heat is transferred to the water on the heating surface of the boiler in the steam system, so that the water is heated into steam at a certain temperature and pressure, which is led out steam to supply workshops. In the combustion equipment part, fuel combustion continuously releases heat, and the high-temperature flue gas generated by combustion transmits heat to the heating surface of the boiler through the propagation of heat, and the temperature itself gradually decreases, and finally is discharged out by chimney.

Composition of Steam Boiler System

 

· Combustion system: Supply fuel to the boiler for heat generation

 

· Steam water system: Consists of feedwater part and steam part, Feedwater part refers to the water that is provided to the boiler for steam conversion. Steam part refers to supplying the steam for building heating or factory processing, which steam is from the steam boiler. 

 

· Control system: a collection of boiler electrical control components,a center for collecting and processing boiler operating signals,and an operation platform for sending execution instructions to each execution unit of the boiler. The control system circuit of the gas steam boiler is relatively complicated, and the core role is the PLC control or DCS control. We can program the PLC logic according to the specific requirements of the customer. The steam boiler control system circuit is mainly composed of logic editing PLC, terminals, modules, control panels, frequency converters, switches, isolation barrier, etc. The circuit drawings are mainly composed of primary circuit diagrams, secondary circuit diagrams, terminal wiring diagrams, PLC point diagrams, etc. Now one of the PLC point diagrams is shown as follows:

 

CN Boiler has always adhered to the concept of full electrical integration in the industrial energy industry, that is, integrating strong and weak current systems such as boiler control, boiler room auxiliary machine control, upper monitoring system, and boiler room power distribution system into a complete electrical package, forming a characteristic industrial energy control system (CN Boiler Multi-Boiler Control System, referred to as CN Boiler- MBCS). 

 

 

Steam Boiler Efficiency

 

The efficiency of your industrial steam boiler can be affected by many factors including fuel quality, boiler design, operating temperature, and pressure. Modern high-efficiency gas steam boilers can achieve efficiencies of up to 95% or higher. However, older or less efficient boilers may have efficiencies ranging from 80% to 85%. The efficiency of an industrial steam boiler is the percentage of energy that is converted to steam. For example, a boiler with an efficiency of 80% means that 80% of the fuel used by the boiler produces usable heat and 20% goes out as waste heat. 

 

Pros & Cons

 

Pros:

High energy efficiency: Gas-fired steam boilers can achieve high energy efficiency, potentially reducing energy costs and greenhouse gas emissions, protecting environment

Fast-produce steam: Gas steam boilers can quickly produce steam for buildings for heating or factory processing.

Easy installation: Gas-fired steam boilers are relatively easy to install and can be retrofitted into existing steam systems.

 

Cons:

Reliance on gas supply: The gas steam boiler requires a continuous supply of natural gas or propane, which may be subject to price fluctuations and supply disruptions.

Regular Maintenance: Gas fired steam boilers require regular maintenance and servicing to ensure optimal performance and safety. If you don’t maintain your steam boiler, it may cause severe damage to the system and even lead to an explosion.

Potential safety risks: Gas leaks or combustion issues can pose safety risks, though modern boilers are equipped with safety features to minimize these risks.
