Low nitrogen condensing gas steam boiler

According to the regulations issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of ChinaAccording to Article 1.4.4 of TSG G0001-2012 "Boiler Safety Technical Supervision Regulations", the category of D-class boilers includes P ≤ 0.8Mpa and 30L ≤ ∨ ≤ 50L. For example, there are Lauter 100Kg, 150Kg, 200Kg, 300Kg, 500Kg, 1000Kg/h biomass pellet evaporators, and Lauter 150Kg, 200Kg, 300Kg, 500Kg, 750Kg1000Kg/h fuel (gas)steam generatorThe water capacity is less than 50L and the rated pressure is ≤ 0.8Mpa, which belongs to the D-class boiler production specification. According to Article 13.4 of the regulations, products that meet the production scope of D-class boilers do not require independent boiler rooms, installation notices, and installation supervision inspections.

1. Waveform furnace chamber: This series of boilers adopts waveform furnace chamber, which not only enhances the disturbance of flue gas, but also increases the radiation heat transfer area; It not only increases the strength of the furnace liner, but also effectively reduces the expansion stress of the furnace liner; It not only enhances the heat transfer effect, but also promotes the combustion of fuel inside the chamber.

2. The welding process of smoke pipes and firebox tube plates: The process measures of pre expansion first, eliminating the gap between the pipes and tube plates, and then welding are adopted to effectively prevent possible corrosion in high temperature areas. Threaded smoke pipes are used for smoke pipes.

3. Symmetrical hinge connection for front and rear smoke box doors: The front smoke box adopts a double-layer structure with good insulation effect, and the smoke box door adopts a hinge structure for easy opening, maintenance, inspection, and cleaning.

4. All stainless steel condenser: A condenser is added at the tail of the flue, which absorbs latent and sensible heat from the flue gas, increases the inlet temperature of the boiler, reduces the exhaust temperature, and increases the heat rate of the boiler to over 98%. (Note: During the use of the boiler, the inlet and outlet valves of the condenser must be kept open.).

5. The control system adopts a floor standing control cabinet intelligent full touch screen type, fully automatic operation, with automatic water replenishment, automatic pressure setting, combustion start stop and fault self sound and light alarm functions. It is easy to operate and safe to use. It can be optionally equipped with a flue gas recovery type or a premixed surface combustion type ultra-low nitrogen burner, achieving an ultra-low nitrogen emission standard of 30mg.

6. Featuring multiple safety protection functions, equipped with imported pressure controllers and safety valves to ensure safe operation.

Steam is required for the processing of industrial products such as petrochemicals, rubber, food, papermaking, textiles, printing and dyeing, chemicals, and pharmaceuticals. It can also be used for cooking, heating, boiling water, and other domestic hot water in service industries such as enterprises, hotels, and guesthouses
