The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)

Sep 08, 2019 · How to calculate the power consumption of the electric boiler? The electric boiler uses electric energy as the energy source, uses electric resistance or electromagnetic induction to drive the heat, and when the heat medium of the boiler heats the heat medium water to a certain parameter (temperature, pressure), the external output has the rated working medium (steam or hot water).

Aug 26, 2011 · The first step is to understand the load-versus-efficiency characteristics of a typical package boiler. Table 1 shows performance variation as a function of load. The boiler with an economizer generates 100,000 lb/h of saturated steam at 400 psig using natural gas. At load, the exit gas temperature is 320 °F. Excess air is 15%.

Nov 03, 2006 · Steam Boilers & Appurtenances, Combustion & Instrumentation Controls, Deaerators, Exhaust Systems, Heat Exchangers, Heat Pipes, Industrial Pumps, Water Heaters, Water Softeners, Boiler Seminars, Services & Parts. 3 Common Boiler Formulas BOILER HORSE POWER What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi?

Apr 20, 2010 · btu/lb for 30 psig steam and 857.4 btu/lb for 150 psig steam. (Ref. saturated steam tables) 4. m s 30 = 749,700/928.7 = 807 lb. 5. m s 150 = 749,700/857.4 = 874 lb. The latent heat of condensation for 150 psig steam is smaller because the enthalpy of the condensate increases much more than the enthalpy of the steam as the steam pressure increases.

Mar 24, 2020 · It is a quick method for boiler efficiency calculation. The percentage of total heat output vs heat input is calculated to establish boiler performance. Direct Boiler Efficiency = Heat output / Heat Input X 100 Or Direct Boiler Efficiency = Q X (h2 – h1) / (q X GCV) X 100. Here, Q = Qty of steam …

l. Steam drum and boiler tube system maximum design temperature specified on data sheet, superheater design temperature per code. m. Total continuous and intermittent blowdowns shall not be more than allowable figure specified in the boiler data sheet of steam generated, Vendor to specify capacity at …

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 = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

The Boiler Sizing Chart will help you to identify the style of radiator, as well as square feet of radiation per section. With these calculations, you will be able to determine the total lineal feet of radiation as well as the total BTUH load. A boiler recommendation can be made based off of the total BTUH load calculated. Boiler Sizing Chart.

The boiler efficiency calculator estimates savings based on scale reduction in a firetube boiler using U.S. Department of Energy data. A qualified vendor or personnel should assess and remove scale as applicable. After scale removal, maintain proper water chemistry for the specific boiler type and pressure to minimize reoccurrence. 2.
