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 when certain coal types are shut down, but not smoke). Harmful gases and substances are combusted and utilized, overcoming the challenge of incomplete combustion in chemistry. 2. Energy Saving: ① Large heat exchange area and long path in the W-type resistance chamber, 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 coal costs. 3. Dust-Free: Static combustion, with dust not easily rising. When flame-carrying dust (extremely rare) 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, allowing for one-time coal loading, slag removal, and ash cleaning. 5. Cost-Effective: No restrictions on coal types, saving funds, and offering economic benefits.沫煤 and lump coal (below 8 cm) utilization ratio: 1:2 in summer, 2:3 in winter. 6. Fast Ignition and Long Combustion 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, wind windows, coal storage bin, W channel, and three-level air control for temperature regulation. 8. Working Principle: In the coal bin, fuel slowly descends under gravity to supplement the combustion layer. It maintains preheating, gasification, combustion, and ash cooling at all levels. Strong heat is exchanged in the lower temperature area of the boiler, with a 180-degree turn-around exchange. 9. It is an atmospheric pressure boiler, no need for a boiler operation permit or operator certification.
