Easy installation skid mounted assembly including control console. Maximum safety - steam drum located outside of firing zone. The hot gases envelope the entire tube surface making maximum use of both radiant and convective heat to achieve very high heat transfer rates. Water at saturation temperature is drawn from the steam drum and forced through the coils at three times the maximum steaming rate by the recirculating pump. The water is then carried back to a steam lance, in the top of the same drum, where steam is released and effectively separated.
Solids collect at the bottom of the drum and are blow out when the blow-down valve is opened.
A pressure sensitive control which responds to the steam pressure in the drum, regulates the supply of fuel and air to the burner and provides eff icient combustion over the complete modulating range of the boiler. High eff iciency is obtained, without thermal shock, over the full operating range, not only at rated output. This page designed by Constance Johnson .
