Embodiment
[0026] Example: such as Figure 1-3 As shown, the present invention is a low-nitrogen condensing gas-fired steam boiler free of procedures, including a boiler skid base 2 and a boiler body 6 fixed on the boiler skid base 2. The structure of the boiler body 6 is that the upper and lower annular headers The vertical water pipes gathered at both ends are arranged in two rings. The vertical pipe 20 adopts finned tubes. This design expands the combustion chamber, and the finned tubes greatly increase the radiation area of heat transfer. The flue gas is evenly distributed along the 360° ° To the arranged water pipes for radiation circulation and heat exchange, use a smoke baffle between every two tubes of the outer ring tube to reduce the flow area of the smoke gas, thereby speeding up the flow rate of the smoke and improving convective heat transfer, and finally flow to the rear Smoke outlet; an integrated economizer and condenser 3 and a water tank 8 are arranged above the boi...

Abstract
The invention discloses a using-procedure-free low-nitrogen condensation type fuel gas steam boiler. The using-procedure-free low-nitrogen condensation type fuel gas steam boiler comprises a chimney,a boiler prying platform base, an integrated energy economizer and condenser, a low-nitrogen burner, a steam valve, a safety valve, a boiler body (including fins, smoke guide plates, an upper collection box, a lower steam-water separator, a lower collection box, an upper steam-water separator, a water inlet and vertical pipelines), an independent downcomer, a water tank, a water feed pump, a liquid level controller and a boiler control cabinet. According to the using-procedure-free low-nitrogen condensation type fuel gas steam boiler, a wall smooth pipe serves as a heat exchanging water pipe,a water pipe with the surface connected with the thick fins in a welded manner serves as a heat exchanging pipe, and the heat exchanging area is increased by 2 times under the same length of the waterpipe; according to the boiler, the service life is prolonged, and the conversion efficiency is also improved; the steam-water separation effect is good, and high-quality steam is obtained; using is convenient, the using range is also enlarged, the energy loss can also be reduced, and meanwhile the discharge amount of nitric oxide is also reduced.
Description
technical field [0001] The invention relates to a gas-fired steam boiler, in particular to a procedure-free low-nitrogen condensing gas-fired steam boiler. Background technique [0002] Disadvantages and deficiencies of existing gas boilers: [0003] According to the requirements of the national "Boiler Regulations", currently most manufacturers in the industry do not need to go through the use procedures. The single rated steam volume of the gas-fired steam boiler is less than 200KG / H, and the gas-fired steam boiler with more than 200KG / H needs to be registered for use and requires operators. Work with a certificate, to be regularly inspected. The output of a single rated steam volume of 200KG / H is too small to meet the user's higher demand for steam volume. If a boiler that requires inspection is used, the boiler occupies a large area, which brings many restrictions on the use site, users and procedures, and also increases the cost of equipment use and long-term manage...
