In many systems, the blowdown rate is determined according to total dissolved solids. In other systems, alkalinity, silica, or suspended solids levels determine the required blowdown rate. For many years, boiler blowdown rates were established to limit boiler water contaminants to levels set by the American Boiler Manufacturers' Association Get Price

The primary function of a blowdown valve is to control the concentrations of suspended & total dissolved solids (TDS) in the boiler. Boiler blowdown is a severe service application which results in rapid erosion and wearing out of conventional valves. Types of Blowdown valves.

The key is good control of TDS. Automatic blowdown control systems with continuous blowdown TDS measurements are available on the market. Example: Consider a 23 t/h boiler operating at 860 kPa (about 50 000 lb./h at 125 psig). The blowdown water contains 770 kJ/kg (330 Btu/lb.).Get Price

An automatic blowdown continuously monitors the quality of feed water as well as the quality of water inside a boiler shell and automatically opens as soon as the boiler water TDS exceeds the permissible operating limit.This type of blowdown helps remove a maximum amount of dissolved solids with only minimal loss of water and heat from the boiler.Get Price

A highly exothermic waste requires a cool- ing medium such as excess air, steam, or water for temperature control. Configuration 2-1.2 is an incinerator fitted with a heat recovery boiler. The boiler, with economizer, can recover approximately 70% of the heat energy supplied to the incinerator by the waste and fuel. 2-11Get Price
Figure 3.14.5 shows the recommended layout for multiple boiler installations where the bottom and TDS blowdown lines are taken back separately to the blowdown vessel. Manifolding should be at the vessel and not at the boiler. Separate connections are required on the vessel for bottom blowdown and for TDS blowdown return lines.Get Price
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Get Price
