What does the rated output of gas-fired boiler mean?

04 Nov 2022

gas-fired boiler uses natural gas, biogas, coke oven gas, etc. as fuel, it has high combustion efficiency, and its emissions are commonly used energy equipment in food, chemical, building materials, medicine and other industries. The rated output of gas-fired boiler is generally used to describe the heating capacity of boiler. Here, ZOZEN Boiler will take you to learn how to choose the rated output of gas-fired boiler.

Rated output of gas-fired boiler

The rated output of the gas boiler refers to the evaporation capacity that the boiler can achieve when the boiler has rated steam parameters, rated feed water temperature, and the correct fuel selection, and is one of the main parameters of the boiler under the premise that the design efficiency of the boiler can be guaranteed.

For steam boilers, the rated output of gas-fired boiler is also called rated evaporation, and the unit is ton/hour; for hot water boilers, it is called rated heat output, and the unit is MW (the old unit is 10,000 kcal/hour).

The rated output range of ZOZEN WNS series gas-fired boiler is 1-20t/h.

The gas-fired boiler is a wet-back internal combustion boiler, it is designed with a large-diameter corrugated furnace, which effectively increases the heat transfer area of the furnace, has the characteristics of full-automatic operation, and runs reliably and stably for a long time. In addition, the self-developed high-efficiency heat transfer element, the threaded smoke tube, effectively improves the thermal efficiency. The boiler has simple structure and small floor area.

The rated output range of SZS gas-fired boiler is 2-110 t/h.

The structure of the gas boiler is a D-type arrangement structure, the right side is the furnace, and the left side is the convection tube bundle. The boiler adopts a full-membrane water-cooled wall structure, which has good sealing performance and a large radiation heating area. Reasonable steam drum size and steam-water separator configuration can reduce steam with water and improve steam quality. Because it is a water tube boiler, the boiler has a strong pressure bearing capacity and a larger parameter range.

As a professional gas boiler supplier, ZOZEN Boiler provide WNS and SZS series gas boilers with a wide range of rated output, and are characterized by safety, reliability, high efficiency, energy saving and environmental protection, convenient maintenance, and automatic intelligent control. The thermal efficiency of condensing gas steam boilers is as high as 98%, and the low nitrogen emission of nitrogen oxides below 30mg/Nm³ can be achieved.
