I. Product Introduction 1. Environmental Protection: No smoke produced, no carbonation or reduction reactions, eliminating dust pollution. The boiler emits transparent exhaust gases during operation (a small amount of white vapor may be released temporarily during shutdown of certain coal types, but it is not smoke). Harmful gases and substances are burned and utilized, overcoming the challenge of incomplete combustion by chemistry. 2. Energy Efficiency: ① Large heat exchange area and long path with W-resistance chamber heat exchange, ensuring full energy utilization; ② Low flue gas velocity, reducing heat loss; ③ Volatile heat is no longer wasted (traditional furnaces cannot fully utilize it), achieving energy enhancement and nearly halving the coal costs. 3. Dust-Free: Static combustion, with dust not easily floating. When flame-carrying dust (rarely) passes through the W channel, it naturally falls due to gravity and centrifugal force, cannot be discharged, and the chimney does not spew dust (no dust removal equipment needed, no additional costs); dust emission is lower than that of oil and gas boilers. 4. Convenience: Equipped with a coal storage bin, coal is loaded once, slag is discharged once, and ash is cleaned once. 5. Cost-Effective: No restrictions on coal types, saving funds, and offering economic benefits.沫煤、块煤 (less than 8 cm) utilization ratio: Summer 1:2, Winter 2:3. 6. Fast Ignition, Long Burning Time. 7. Structure: The technical design of this coal-burning environmental-friendly and energy-saving atmospheric pressure hot water boiler is completely different from existing boiler technologies. It features an inclined furnace chamber, air windows, coal storage bin, W channel, and three-level air control for temperature regulation. 8. Working Principle: In the coal storage bin, fuel slowly descends under gravity to supplement the combustion layer. It maintains preheating, gasification, combustion, and ash cooling at all levels. Strong heat exchanges occur in the low-temperature area at the bottom of the boiler, with a 180-degree turn-around heat exchange. 9. It is an atmospheric pressure boiler, no need for a boiler operation license or operator's certification.
