They are typically made from cast iron or steel. Their construction design may be sectional, portable, fire-tube, water-tube, or special. Domestic heating boilers are generally of low-pressure type with a maximum working pressure of 15 pounds per …Get Price
Fire tubes boilers are also known as a smoke tube boiler. Water-tube boiler: Water-tube boilers are those boilers in which water flows through a number of tubes (called water tubes) and the hot gases produced by the combustion of fuel in the boiler furnace while on their way to chimney pass surrounding the tubes.Get Price
The lower-BTUH of a gas water heater (compared with a heating furnace or boiler) will very often be unable to heat the chimney interior sufficiently to develop a draft. The result is a back-draft of combustion products out of the water heater's draft hood and into the building.Get Price

Hot water heating boiler. A boiler in which no steam is generated, from which hot water is circulated for heating purposes and then returned to the boiler, and that operates at water pressures not exceeding 160 pounds per square inch gauge (psig) (1100 kPa gauge) and at water temperatures not exceeding 250°F (121°C) at or near the boiler outlet.Get Price

The fuel used is gas on a firm tariff of £0.011/ kWh, and the boiler efficiency is estimated as 80%. Make-up water temperature is 10°C and insulated condensate return lines ensure that condensate will arrive back at the boiler house at 95°C. Consider the water costs to be £0.70/m3 and the total effluent costs to be £0.45/m3.Get Price
Hot water heating system expansion tank / compression tank drain procedure to re-charge lost air: This article describes the steps in draining of a steel compression or expansion tank used on hot water system heating boilers - hydronic heat. Draining water out of a waterlogged expansion tank is a common heating boiler service procedure used to replace a lost air charge.Get Price
Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the …Get Price
