May 04, 2016 · For boilers operating up to 300 psig, the accepted alkalinity range is 200 ppm to 700 ppm, with P being 60% to 80% of Total Alkalinity. Balances alkalinities are no guarantee of clean, trouble-free boilers. However, this is one of the important factors, together with others, that must be properly controlled if the boiler is to be kept clean.View More
Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (h g - …View More
Jun 26, 2017 · Assume boiler is operating at 10 cycles of concentration with feedwater at 205 oF. This equates to a dissolved oxygen content of 0.7 ppm or 0.5 cc per liter. Assume a feedwater demand of 500,000 lbs per day. The desired sulfite residual is 30 ppm.View More
Used Oil Burning Guidelines for burning used oil in space heaters, furnaces and boilers Utility boilers used to produce electric power, steam, heated or cooled air, or Used oil containing 2 ppm but < 50 ppm must be burnedView More
step by step 4) An evaporator having an area of 83.6 m² and a U-2270 W/m²K is used to produce distilled water for a boiler feed. Tap water (specific heat capacity of 4.188 kJ/kg.K) having 400 ppm of dissolved solids at 15.6 °C is fed to the evaporator operating at 1 atm pressure abs. Saturated steam at 115 °C is available for use.View More
thermal efﬁciency. True boiler efﬁciency is the measure of fuel-to-steam efﬁciency. BOILER HORSEPOWER - The evaporation of 34-1/2 lbs of water per hour from a temperature of 212 °F into dry saturated steam at the same temperature. Equivalent to 33,475 Btu/hr. BOILER RATING - The heating capacity of a boiler expressed in boiler horsepowerView More
• persons generating used oil through personal vehicle maintenance • farmers generating an average of 25 gallons per month or less of used oil from vehicles or machinery used on the farm during a calendar year Used oil storage (OAR 340-111-0032; 40 CFR 279.22 and 40 CFR, Part 112) In storage units, used oil must be stored in tanksView More
Boiler Horsepower What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP Boiler Horsepower BHP = (LB/HR*fe)/34.5 Lb/Hr Pounds per Hour BHP = 21500 * 1.08 / …View More
TDS = 5,000x0.7μS/cm. TDS = 3,500 ppm. Alternatively, the battery powered, temperature compensated conductivity meter shown next is suitable for use up to a temperature of 45°C. It is necessary to measure the conductivity of the boiler water inside the boiler or in the blowdown line.View More
It is applied to a boiler operating at 20 cycles with 0.1 ppm feedwater hardness. Feedwater dosage is 8.8 ppm to yield 10 ppm free EDTA and 26 ppm polymer. 4 If the hardness goes up to 1 ppm or the product is used in another system where the hardness is 1 ppm, the feedwater dosage increases to 43 ppm to obtain 10 ppm free EDTA.View More
If maximum permissible limit of TDS as in a package boiler is 3000 ppm, percentage make up water is 10% and TDS in feed water is 300 ppm, then the percentage blow down is given as: = 300 x 10/ 3000 = 1%. If boiler evaporation rate is 3000 kg/hr then required blow down rate is:View More
Conventional shell boilers are normally operated with the TDS in the range of 2 000 ppm for very small boilers, and up to 3 500 ppm for larger boilers, provided the: Boiler is operating near to its design pressure. Steam load conditions are not too severe. Other boiler water …View More
ENERGY STAR Most Efficient 2020 — Boilers. Navien’s NCB is the first high efficiency compact wall-hung condensing combi-boiler with the capacity to supply both heat (up to 120k BTU/h) and domestic hot water (up to 199k BTU/h) for a whole house. Takes up 80% less space than a traditional floor standing boiler and storage tank.View More
TDS = Total Dissolved Solids (ppm) ρ = relative density of the boiler water at 15.5oC This is a manual method requiring measuring a cooled down sample with a very sensitive hydrometer. Measuring TDS with the conductivity methodView More
The blowdown rate can be calculated with Following Formula. qBD = qS fc / (bc – fc) Where: qBD is blowdown rate in kg/h. qS is steam consumption in kg/h. FC is Total Dissolved Solids – TDS – in the feed water is ppm. bc is maximum allowable Total Dissolved Solids – TDS – in the boiler water in ppm.View More
If burner modifications are utilized exclusively to achieve low NOx levels (30 ppm), adverse affects on boiler operating parameters such as turndown, capacity, CO levels, and efficiency may result. It is important to address all aspects of boiler performance when selecting NOx control technologies.View More
