Table 1 shows capacity of a natural gas line for a given initial pressure with a 5% pressure drop. For example, consider a 500 hp boiler, which requires 20,925 cu.-ft. / hr. A 5 psi initial pressure is available for 100 ft. of pipe. To find the correct pipe size, go to the line for initial gas pressure reading 5 pounds. Now move to the

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.

Pretreatment 44 Disadvantages of RO as compared to a softener boiler pretreatment program include: x Increased electrical costs. x If acid pretreatment is used, acid handling will be required. x Product water flow rate is pretty much fixed while ion exchange can manage variable flows. x An antiscalant may be necessary upstream of the RO. x With polyamide (PA) membranes, chlorine must be removed

Evaporation depends on temperature through vapor pressure of the liquid to be evaporated. A high temperature gives a high vapor pressure. At boiling temperature of 100 degree Celsius, vapor pressure of water is equal to 1 atmosphere. That means if

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of

Look at the evaporation rate. Knowing how much water, or water as steam, the boiler can put out is good, but don't pick a pump size yet. ASHRAE recommends sizing your return pump for two to three times the boiler's evaporation rate—so the return unit can return condensate faster than the boiler can put it out.

It has been found that 172 lb/hr of high-pressure steam is capable of compressing 306 lb/hr of spent steam from the first effect, resulting in a total steam feed to the evaporator of 478 lb/hr. The remainder of the falling-film triple-effect evaporator is similar to the straight steam system, except the second and third effects are smaller as a

Boilers are classified as either low pressure or high pressure and are constructed to meet ASME Boiler and Pressure Vessel Code requirements. Low-pressure boilers are limited to a maximum working pressure of 15 psig (pound-force per square inch gauge) for steam and 160 psig for hot water (2).
