Mar 17, 2022 · Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.

Read MoreBefore we get into boiler maintenance, lets talk efficiency. Boilers draw in the fresh air, heat it, and send it out the stack. Optimal conditions would generate the smallest amount of flue gas (exhaust gas that's expelled) at the lowest possible temperature. The boiler system takes in cold water, heats it to steam, and uses the heat.
Read MoreAERCO Condensate Neutralizers are ideal for neutralizing condensate from condensing boilers, water heaters and furnaces operating on natural gas or propane. Condensate is acidic and has the potential to harm the environment and the sewer system. The AERCO Condensate Neutralizer will raise the pH of the condensate to a more neutral level before

Read More4. Lower the Waterline. The open space inside a boiler at the top is crucial to making dry steam. This area, called the steam chest, is where water droplets fall out of the steam, rather than being carried out into the system. The larger the steam chest, the drier the steam. And the lower the waterline, the larger the steam chest.
