Water treatment outside the boiler
Before entering the boiler, raw water is treated with water treatment equipment to remove impurities such as hardness, salinity, dissolved oxygen, etc., so that the feed water can meet the water quality requirements specified by steam boiler. Common water treatment equipment includes sodium ion exchange water softening equipment, ion exchange desalination equipment, reverse osmosis water purification equipment and thermal oxygen removal equipment.

The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F. The operating pressure for hot water heating systems usually is 30 psig to 125 psig (hydrostatic). Under these conditions, there is a wide range of hot water boiler products available. If system requirements are for hot water of more than 250°F, a high-temperature water boiler should be considered.
A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
Discharging high-temperature flue gas generated by a biomass-fired boiler efficiently and safely is crucial for boiler operation, environmental compliance, and energy recovery. These gases, if not handled properly, can lead to energy inefficiency and increase the emission of pollutants. ZOZEN Boiler, as a professional industrial boiler manufacturer, incorporates advanced technologies and strategies to manage and utilize high-temperature flue gases from biomass-fired boilers. Here's an overview o...

An oil boiler's burner lockout is a common issue that can disrupt heating processes in various industrial and residential settings. This problem occurs when the boiler's control system detects a fault and, as a safety measure, shuts down the burner to prevent further damage or hazards. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the importance of understanding the underlying causes of burner lockouts to ensure timely and effective solutions. Here, we explore the pri...
Selecting a biomass-fired boiler for industrial applications involves careful consideration of various parameters to ensure efficiency, sustainability, and cost-effectiveness. Biomass boilers offer an eco-friendly alternative to fossil fuel-based boilers by utilizing renewable resources like wood chips, pellets, and agricultural waste. When choosing a biomass-fired boiler, pay attention to the following parameters:
1. Fuel Type and Availability:
Type of Biomass: The type of biomass fuel availa...
(Question details) specific performance:The gas boiler is powered on, press start, the motor does not turn. Answer: Fault reason:1. Insufficient pneumatic locking.2. The solenoid valve is not sealing, and there is air leakage at the joint. Check the lock.3. The thermal relay is open.4. At least one of the conditional circuits is not valid (water level, pressure, temperature and to check whether the program controller is energized to start). Troubleshooting:1. Adjust the air pressure to the requested value.2. Clean or repair solenoid valve pipe joint.3. Check whether the component is damaged and motor current by reset.4. Check whether the water level, pressure and temperature exceed the limit.ZOZEN gas-fired boiler adopts automatic control to control the operation, combustion, water level, temperature and steam pressure. In case of such problems, the system will automatically prompt the error code.
