Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").
Today’s Packaged Firetube Boilers are available in a wide variety of designs. The basic combustion gas flow pattern for all designs has the actual combustion occurring in the furnace with hot gases passing through the full-length banks of firetubes. These boilers are available in single pass, 2 pass, 3 pass and 4 pass patterns.

When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from standard No. 2 oils have been achieved. Low nitrogen oil is used most frequently in southern California.
opportunities for the hot gasses to transfer heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-
1.4.2 Firing Practices3-5 There are three major types of boilers used for natural gas combustion in commercial, industrial, and utility applications: watertube, firetube, and cast iron. Watertube boilers are designed to pass water through the inside of heat transfer tubes while the outside of the tubes is heated by direct contact with the
Our engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance.
