What is a condensing boiler?
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.

Bangladesh is one of the world’s major producers and exporters of garments and textiles. With a well-developed industrial chain covering textile, dyeing, printing, and garment manufacturing, long-term demand for industrial steam remains strong. In production processes such as dyeing, washing, drying, and finishing, steam boilers play an important role in ensuring stable heat supply. As local textile enterprises place greater emphasis on energy consumption control, fuel utilization, and ope...21 Apr 2026 -
In Pakistan, garment manufacturing and fabric processing remain important parts of industrial production. For these factories, steam is not an auxiliary utility but a core part of the production chain. Processes such as dyeing, drying, heat setting, and finishing all require a stable and continuous steam supply. Any fluctuation in steam output may affect production rhythm. Against this background, more textile companies in Pakistan are paying closer attention to fuel adaptability, operating sta...14 Apr 2026
