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).

Here are the key advantages of shell (fire-tube) boilers:

Simpler design and construction: Fewer components, straightforward layout, easy to install and commission.

Lower initial cost: Typically cheaper to purchase and set up than water-tube boilers of similar duty.

Ease of operation: More forgiving to operate; simpler controls and less stringent water-quality demands.

Rapid steaming from cold: Good heat storage in the shell allows relatively quick start-up and response to load changes.

High thermal inertia: Acts as a steam reservoir, smoothing short-term load fluctuations and reducing burner cycling.

From a capacity perspective, a 35-ton gas boiler refers to an evaporation capacity of up to 35 tons per hour under rated working pressure. In terms of dimensions, the boiler body is approximately 11.5m × 4.4m × 4.2m, but it can be customized to meet actual needs. 

Advantages of Low-Pressure High-Temperature Boilers

One of the main advantages of low-pressure high-temperature boilers is their ability to provide high-temperature steam or hot water in a more controlled, safer manner. High-pressure systems can pose a safety risk if not properly managed, and the lower pressure of these systems makes them inherently safer to operate.

Also, many processes and applications do not require high pressure, but do require high temperatures. For these applications, a low-pressure high-temperature boiler is an ideal solution.

The circulating fluidized bed boiler has the advantages of high efficiency and energy-saving, good combustion effect, stable and reliable, convenient ash handling, and wide application range. It is a boiler technology with broad application prospects.

Simply put, it is a thermal oil boiler fueled by natural gas. Natural gas is widely recognized for its cleanliness, environmental friendliness, and high combustion efficiency. Integrating natural gas with thermal oil boilers represents a powerful synergy! Natural gas thermal oil boilers not only deliver stable, high-temperature heat but also offer exceptional environmental benefits due to minimal pollutant emissions from combustion.
