The condenser is a vertical condenser with process vapours on tube side and boiler feed water on shell side. The outlet of the shell side is a two phase flow. Pipe thickness reduction of the shell side outlet pipe is observed for last couple of years. We replace the piece of pipe every one year.
Dec 29, 2018 · Baseboard heaters, or hot-water home heating systems, quietly provide relatively evenly distributed heat throughout a building. Water is heated in a boiler usually fired by propane, natural gas or oil. A pump circulates the heated water as steam to baseboards located near the floor of exterior perimeter walls throughout the building.
Jun 04, 2003 · Venting Systems. As the efficiency of a boiler goes up, the temperature of the flue gases go down, and the gases are more likely to condense in the flue. When combustion efficiency exceeds approximately 83%, there is a good possibility that the flue products will condense.

Boiler operators and technicians should pay close attention to three key safety devices to protect personnel, equipment, and the facility: Safety valves. The safety valve is the most important safety device in a boiler or domestic hot-water system. It is designed to relieve internal pressure if a range of failures occur within the system.
Lattner Boiler Company manufactures both fuel-fired and electric boiler systems. Fuel fired systems include vertical tubeless steam boilers and horizontal firetube steam, hot water boilers. Electric boilers include horizontal steam boilers, and cabinet style steam boilers.
Boiler isolation allows contractors to turn off water flow to and from a boiler quickly. Conclusion. High-efficiency gas-fueled wall-hung condensing boilers provide a range of high-performance heating and water-heating options for the multifamily-housing industry.
Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
The result was then added to the other flue gas constituents in Equations 2 to calculate the total weight of dry gas per cubic foot of fuel. @ A @ A Eq-5 The energy loss from sensible heating of the flue gas is equal to the product of the weight of the flue gasses, the specific heat, and the change in temperature.
Air exit tanks on heating boilers and circulator pump mounting location - some heating boilers use an air exit tank mounted on the hot water header above the heating boiler to combine the function of an EXPANSION TANK with the AIR BLEEDER VALVE or air purge valve to rid the hydronic (hot water) heating system of un-wanted air.
Jan 19, 2015 · The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.
Dec 12, 2018 · Gas boiler installation must be carried out by a Gas Safe registered installer. There are a number of different types of domestic boiler. Conventional boilers. Conventional boilers (sometimes referred to as traditional, heat only or open vent boilers) can supply central heating and hot water for sinks, baths and showers.
the form if a condensing boiler with efficiency in SEDBUK band A or B is to be fitted. The assessment gives a YES/NO answer to whether it is reasonable to fit a non-condensing boiler in a particular building for a specified fuel (gas, LPG, or oil). If the answer is ‘NO’, then a condensing boiler should be fitted unless some other way can
O&M Ideas for Major Equipment Types . Water-tube boilers are available in sizes ranging from smaller residential type to very large utility class boilers. Boiler pressures range from 15 psi through pressures exceeding 3,500 psi. 184.108.40.206 Electric Boilers

When the demand for domestic hot water or heating ends, the gas-control valve closes, and the boiler goes into standby mode until the next call for hot water or heat. Benefits. Benefits of condensing boilers include: A multifamily-housing installation. Space savings. Wall-hung condensing boilers are smaller and lighter than traditional boilers.
Vent Dampers Overview. Gas fired furnaces, small boilers and water heaters require a flue that has a good draft in it to get rid of the products of combustion after most of the heat has been removed. Newer appliances have fans and are called ‘forced’ or ‘induced’ draft venting. Older equipment and most small boilers still rely on
2) Ash deposits on water walls and on boiler tubes and scale deposits on the water side tube surfaces act as insulation, reducing heat absorption by the boiler water from the flue gas. The Three basic strategies for minimizing stack gas heat loss are:- Minimizing excess air:- Excess air is defined as the air supplied to the furnace beyond the air required for complete combustion.
