heating surface area of boiler

heating surface area of boiler are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.

Determining Boiler Capacity from Heating Surface Are

Dec 10, 2004· Determining Boiler Capacity from Heating Surface Area. I am talking about an older (1972 vintage) D-style watertube steam boiler with a design pressure of 250 psig. The nameplate states that the surface area is 3089 sq ft. The burners I know are oversized, but I am trying to determine by how much they are oversized.hp is calculated by the blr mfr but probably have 400 to 600 hp if you calc 5 sfhs to 8 sfhs per bhp. newer boilers are squeezed to 5 or 6 sfhs/bhp but older mfrs were calulating 8 to 10 sfhs/bhp ER1Steam generating capacity can be determined from heating surfaces on a FT boilers but w/WT boilers the steaming capacity determination is a little more complicated because of their constructions. W/ FT boiler, rule if thumb is 5-7.5 lbm/hr of steam per square ft of heating surface for continuous firing. W/ WT boilers I found it best to use the size of the combustion chambers to determine continous steam production. I dont remember the numbers that I used in the past and I'll dig thru my archive to get you that information in a few days. I do remember the reference from which I got those numbers and that was Kent"Power" -edition probably dating around the 1940's. On the other hand ASME power code VI uses the heating surfaces to determine the safety valve relieving capacities of both FT and WT boiler drums and superheaters and that could be a starting point for your information but those values are normally greater than the actual steam production of both boilers.Spirax Sarco has a module on boiler ratings and boiler horsepower in their website learning centre. Block 3, module 3.5 I think. Not too sophisticated but it might be worth a lookSince Your D-type WT boiler has water-cooled metallic walls,the average heat release in the furnace is 30,000 btu/hr per cu.ft. of furnace volume for continuous operation and 60,000 for peak operation per Kent"Power" 12 th Ed. pg 7-75 table 3. At rating, for WT. boilers, steaming rate is 3 1/2 lbs saturated steam per sq.ft of heating surface, however dont us this value since WT boiler will produce steam well over rating.For example,a horizontal WT boiler can generate 15.1 to 22.5 lbs of saturated steam per sq ft of H.S.. Since the only rule of thumb that I know for WT boilers is table 3 mentioned above, I would use that as my starting point to determine steaming rate. Also contact the manufacturer and if he is no longer in business read literature on boilers. You will eventually develop the info that you seek.Rat, How about something really approximate such as comparing outside dimensions to modern D-type boilers ? In my opinion, if I have a "box" with the same overall dimensions as a newer design, I would call the capacities approximately equal. (this assumes that all D-types have approximately the same efficiency) (Look at page #4) MJC1 tph steam boiler heating surface area to calculate – oil › Projects2013-9-12 · Richard: Heating surface area of a boiler is usually expressed in square feet (12" x 12" = 144" or 1 sq. ft.), and all too often tubes and firebox sheets are listed. boiler heating surface calculation .

boiler horsepower - Siz

Jul 22, 2004· Origin of the boiler horsepower. The earliest such measure of boiler output, the "nominal or rated boiler horsepower," was simply based on the area of the boiler's heating surface. Each 10 square feet of surface represented 1 boiler horsepower, so a boiler with 100 square feet of heating surface would be rated at 10 boiler horsepower.
