Rinnai M-Series 120000-BTU Natural Gas Boiler. Rinnai M120CN residential condensing combination, natural gas boiler is compact, wall mounted designed for easy installation as a retro-fit to traditional less efficient boilers and can deliver whole house heating and domestic hot water heating for homes with up to three bathrooms.
The boiler carries a manufacturer's 20 year warranty due to failure from thermal shock. The Unilux Water Tube Boiler is available as steam hot water, high temperature hot water ( HTHW) and steam in capacities from 31 to 1500 HP firing natural gas or No 2 oil.
Hot Water Hydronic Boilers & Heaters. 29 products. Hydronic boilers and heaters use hot water or steam to provide the primary source of heat in cold weather. They connect to the building's hot water supply and use gas or oil as fuel. Hydronic duct heating and cooling coils use hot or chilled water to produce supplementary warm or cool air.
Designed with simplicity, efficiency and safety in mind. We have designed our Parker Hot Water Boiler Series specifically to provide the building heating and industrial processing industries with a Super Quality Boiler with Unequaled Advantages in Safety, Long Life Service and Economical Operation. The simplicity of the System with no FGR fan or valve, allows normal boiler operators to adjust and service …
The most common Industrial Hot Water Boilers are two or three passes; each pass being a different set of tubes that the hot flue gas travels through before making a turn within the boiler. In addition to these are reverse flame Industrial Hot Water Boilers where the burner fires into a blind furnace and the combustion gases double back on themselves within the same chamber to ensure full combustion.
In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.
Conservationist® Burkay® high efficiency gas boilers are designed for indoor use in installations requiring higher inputs (up to 670,000 Btu). They're rust-proof because water comes in contact with nothing but copper, brass or bronze. And the Burkay burner features a patented design that maximizes combustion efficiency. View Products.

Basics of hot water heating boilers - Specifying Engineer
Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).? Steam and exit gas temperatures. Upon switching from coal to natural gas, heat transfer characteristics of a boiler will be impacted.
Commercial Watertube Boilers. Types: Straight tube; flextube, membrane wall type. Capacity: ½ million BTU to 18 million BTU. Typical uses/applications: Wide range of uses from hot water and low pressure steam heating loads to process loads. Typically used in hybrid heating systems and when oil firing is required, and for smaller process loads.

Sep 18, 2020 · A water-tube boiler is one in which the fluid to be heated passes through a series of pipes or tubes and the combustion gases are external to the tubes. Heat from the combustion gases passes through the metallic tube walls. Large water-tube boilers are constructed with ferrous materials.
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …
