In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler.Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler.Get Price
A reboiler temperature in the range of 350° to 400°F insures adequate heat transfer to the ceramic packing in the still column. The still column operates best (allows the steam to escape) when the vapor outlet temperature is between 215° and 225°F. When the temperature reaches 250°F and above, glycol vaporization losses increase.Get Price
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Get Price
Water or steam injection reduces flame tempera-tures and thus thermal NO x. Water injection is especially effective for gas turbines, reducing NO x emissions by about 80% at a water injection rate of 2%. For a gas turbine, the energy penalty is about 1%, but for a utility boiler it can be as high as 10%. For diesel-fired units, 25–35% Get Price
(b) Natural gas if reformed by steam, control problems are related to combustion, emission and boiler blow down liquids, (c) NO x /SO x depends on the materials burnt, flame temperature and stoichiometry, (d) Flue gas with low NO x, if process gas used NH 3 reduces formation of NO x,Get Price
Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70°C (158°F), inhibiting Legionella growth. Avoid using raw steam from the central heating boiler due to contamination with corrosion inhibitors and anti-scaling chemicals.Get Price

Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.Get Price
BIOMASS BOILERS A Biomass boiler is an alternative, renewable energy solution to a traditional boiler. Biomass boilers are used in residential properties, but can also heat smaller commercial properties too. A biomass heating system using a boiler with a 45kw output or less, is considered a domestic sized boiler.Get Price
Historically, old boilers are considered 50 – 75% efficient, which means that a half to a quarter of the energy supplied to the boiler was wasted. Modern high-efficiency boilers (gas, LPG and oil) and biomass boilers have a much-improved efficiency of around and above 90%, with only small amounts of heat lost through the flue.Get Price
