The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Thermodyne Boilers, Industrial Chimney manufacturer in India, have successfully designed, manufactured, supplied and erected both structure and self-supported chimneys in compliance with IS-6533 (part-1&2) to many of our clients. TES is one of the leading boiler spares & Industrial Chumney manufacturers and suppliers.
Standard Z9.5 recommends a minimum stack height of 10 ft above the adjacent roof line, an exhaust velocity V e of 3000 fpm, and a stack height extending one stack diameter above any architectural screen; National Fire Protection Association (NFPA) Standard 45 specifies a minimum stack height of 10 ft to protect rooftop work-ers.

Stack height requirement based on sulphur dioxide emissions by using the equation - stack height = 14 (Q) 0.3 [where, Q is the emission rate of SO2 in kg/hr] By using simple Gaussian plume model to maintain ambient air quality requirements for all concerned parameters, in the receiving environment.
Quality work at any height. At National Chimney & Stack, we focus on finding cost effective and safe solutions for tall and difficult to access structures. We utilize several methods to reach work areas, and specialize in industrial rope access. NCS is a division of National Boiler Service.
publication "Packaged Boiler Engineering Manual " offers a helpful general overview for typical Firetube boilers and other large commercial and industrial products. Stack design can a significant impact. A good stack design will provide a smooth flow and transition of the flue gas as it exits the building while a poor design that has turbulence

You must apply for chimney height approval if your boiler's fuel consumption either: exceeds 45.4 kg of solid fuel an hour exceeds 366.4 kw of liquid or gas fuel
Mar 01, 2010 · Nevertheless, the stack height determined by the Memorandum will normally be sufficient for condensing boilers with low NOx burners (<0.02g/MJ) with thermal input less than 1 MW burning very low sulphur fuels and discharging above roof level. Larger boilers will require more detailed assessment, using an appropriate dispersion model.
Air Quality Standard Permit for Boilers
7. Stack Size – Pressure drops through the boiler exhaust system should be calculated and in general should not exceed 0.2″ WC. Undersized stacks create excess back pressure on the boiler resulting in combustion problems, inability to make full capacity, or both. There are several very competent manufacturers of boiler exhaust systems.
