As an important pharmaceutical production base in Latin America, Mexico's regulatory agencies have extremely high requirements for the hygiene standards of the production environment and the environmental compliance of energy use. Traditional coal-fired or highly polluting oil fired boilers have gradually been phased out by the market due to excessive emissions, low thermal efficiency, and unstable operation. A leading local pharmaceutical enterprise specializing in the production of over-the-counter drugs, antibiotics, and liquid injections reached cooperation with
Sitong boiler on a WNS series gas fired boiler recently. During the production process of the pharmaceutical production, stable, pure, and controllable steam is required for reaction vessels, sterilization cabinets, drying equipment, and clean piping systems. At present, the customer urgently needs a heat source equipment that can ensure the continuous output of high-quality saturated steam while complying with international low nitrogen emission standards. After multiple rounds of technical evaluation and comparison,
Sitong boiler was selected as its new core thermal equipment supplier.
Sitong boiler's design team customized this WNS3-1.25-Y(Q)series natural gas fired steam boiler for them after fully understanding the customer's needs. This model is designed specifically for industrial applications, with a rated evaporation capacity of 3 tons/hour and a rated working pressure of 1.25 MPa, which can perfectly meet the steam load requirements of medium-sized pharmaceutical production lines. The customer choose natural gas as fuel not only because some regions in Mexico have well-developed natural gas infrastructure and relatively controllable costs, but also because its combustion products are clean and can fundamentally solve the problems of odor and particulate matter pollution in pharmaceutical workshops.
The WNS3-1.25-Y (Q) series natural gas fired steam boiler from
Sitong boiler adopts the classic horizontal internal combustion three passes fire tube shell structure. The boiler is equipped with a large diameter corrugated furnace liner, which not only enhances the elasticity of the furnace liner to absorb thermal expansion stress, but also increases the heating area through the corrugated structure, stabilizing the boiler's thermal efficiency at over 93% and significantly reducing the company's long-term fuel costs. Pharmaceutical production often requires 24-hour uninterrupted operation with extremely high requirements for equipment automation. Ths boiler is equipped the unit with a fully automatic control system based on PLC, integrating a touch screen human-machine interface. The system has multiple safety functions such as real-time monitoring of water level, automatic pressure adjustment, shutdown protection, and overpressure interlock shutdown. The operator only needs one click to start, and the boiler can automatically adjust the balance between combustion load and water level according to the set parameters. In response to the high sensitivity of the pharmaceutical industry to air quality, this boiler is equipped with advanced low nitrogen burners. The generation of thermal NOx can be effectively suppressed by adopting flue gas recirculation (FGR) technology and staged combustion strategy. This feature ensures that the pharmaceutical enterprise in Mexico can expand its production capacity without worrying about environmental compliance risks, thereby achieving the unity of economic benefits and social responsibility.
