LDR Series Small Steam Boilers, Product Performance Advantages: 1. Low Management Costs: Not classified as special equipment, no need for boiler operation permits or operator qualifications. 2. Energy-Saving: Innovative design, compact size, high thermal efficiency, all emissions meet environmental standards. Utilizes a new double drum three-pass structure to increase feedwater temperature, stabilize steam pressure, and achieve high energy conversion rates of over 93%. Produces steam in 2-3 minutes, with flue gas temperatures of 50-60℃ (can use plastic or PVC pipes for the chimney); the preheater employs a serpentine fin pattern to enhance thermal efficiency; Function: Changes the original ambient temperature feedwater to 95-100℃ feedwater (or use this hot water for other purposes), reducing energy consumption of the equipment.
