C. W. WILLIAMS' ARGAND FURNACE. 



Questions relative to the effect of C. W. Williams' Argand Furnace, as answered by the Commanders and Engineers of the undermentioned 



Steamers, 28M March, 1843.

Vessel. 



Do they male less smoke 

 since they were altered .' 



12 months. A great deal of smoke 

 7 months. \ Not much smoke. 



19th April, Yes — a very 

 1841 — say black smoke, 

 two vears. , 



thick 



Birmingham. 



Oriental. 



(From Alexandria) 



A great quantity of 

 smoke was made pre- 

 viously. 



Yes — we smoked very 

 much. 



Nov.23,1843 Made much smoke 

 with the former boilers. 



Always to : Smoked much with 

 these boilers, former boilers. 



9 months A great quantity of 

 dense black smoke 



Going before the wind 

 they smoked consider 

 ably — at other times not 

 so much. 



At times thev smoked, 



A dense black smoke. 



Yes — we smoked con- 

 siderably, as much as 

 any vessel of our class.

Much less smoke, 

 scarcely any to be per 

 ceived. 



Since the alteration 

 there is less smoke than 

 before. 



No smoke is now 

 made except when tires 

 are first lighted, or coals 

 are being thrown on. 



No smoke is now made 

 after the fires are put in 

 good order — a light 

 smoke when men are 

 firing. 



Only when fires are 

 first lighted, or with bad 

 coal. 



Had you a sufficient 



supphf of steam before 



the furnaces were 



altered. 



Does the use of this 

 Hore yon as good or ! Apparatus effect any 

 better command of steam saving of fuel, and to 

 since the alteration f wha' extent .' 



Yes — but 

 much. 



No — scarcely enougl 

 of steam. 



Rather insufficient in 

 steam. 



Yes — a great deal bet- 

 ter, and was enabled to 

 blow off copiouslv 



I should say a better 

 command of steam, 

 though we have new 

 cylinders of larger di~ 

 mensions. 



YVe have now an abun- 

 dant supply of steam. 



We have now a very 

 plentiful supply of steam. 



Voyage from Liverpool 

 to Southampton, smoked 

 much, from both funnels 



Very little smoke now. 



Vc have made very- 

 little smoke since the 

 commencement, with 

 present boilers. 



They now make 

 scarcely any smoke after 

 the fires are well lighted. 



No smoke except when 

 tiring up or making the 

 fires, and then only 

 short time. 



No black smoke now 

 appears while under way 

 but sometimes a little 

 gray colour a few seconds 

 after firing. 



Much less smoke. 



After all is warmed 

 t h rough we do not smoke, 

 only when firing up or 

 aking, and then only a 

 slight volume for a few 

 seconds. 



Smoke is now seldom 

 or never seen. 



No — we had but little 

 except with very good 

 coal — then with great 

 exertion we worked to 

 full power. 



The apparatus attached 

 when the present boilers 

 were pnt in. 



Apparatus always at- 

 tached to present boiler: 

 plenty of steam at all 

 times. 



We had sufficient he 

 fore the alteration. 



We always had a good 

 command of steam. 



A great quantity of 

 smoke. 



A great deal of smoke 



Smoke nearly done 

 away with, except 

 firing, and when raising 

 steam from cold water. 



No smoke now except 

 when the fire is lighted. 



We are convinced we 

 have, and particularly 

 with good coals. 



Sufficient supply o 

 steam. 



Apparatus always at 

 tached — plenty of steam 

 at all times. 



We have quite suffi 

 cient, as we had before. 



1 have always a suffi- 

 cient supply of steam. 



No, we had not suffi 

 cient steam. 



We were always pretty 

 well for steam when 

 using good coals. 



Not over abundant 



Not half enough. 



We have better com- 

 mand of steam ; if the 

 coals are good, we can 

 make any quantity of 

 steam with the greatest 

 ease. 



At all times a sufficient 

 command, and are now to ljcwt. per hour, 

 enabled constantly to 

 blow off steam. 



On the average of trips 

 we save at least 3 cwt. 

 per hour. 



Consumption much 

 about the same as before, 

 notwithstanding about 

 16 horses power added 

 and an increase of two 

 revolutions. 



Consumption of fuel 

 the same as before. 



About four tons of 

 fuel less is now consumed 

 in the trip than before 

 the alteration. 



Yes — this is experi 

 enced when burning 

 good coals, hut not when 

 with a bad quality. 



Apparatus always ap 

 plied to these boilers. 



Apparatus always at- 

 tached, therefore cannot 

 say. 



Without the air 



pipes we made 



16 voyages .. 371 hrs. 



Coals consumed 571 tons 



With the air 



pipes we made 



16 voyages .. 379 hrs. 



Coals consumed 522tons 



Saving . . . . 49tons 



To the best of our 



judgment, about 4 cwt 



per hour. 



We save about 1 cwt 



Very much better. 



We consider that we 

 have a much better sup 

 ply with the air appa 

 ratus — there is no ques 

 tion of it. 



Sufficient steam now. 



Much about the same, 



From the nature of 

 our service I cannot say 



We think we are saving 

 from three to four cwt 

 per hour. For many 

 voyages our consumption 

 averaged 26 cwt. per 

 hour. It was 30 cwt 

 previously. 



The air boxes are a 

 great saving, both 

 fuel and supporting the 

 bridges. 



From 13 to 20 per 

 cent, of fuel is saved 



Y'es, at least one-third 



.Since the above was printed, the Queen Victoria (in Liverpool) and the Bronda (in Glasgow) have been added to the list, in both of which 



the apparatus has been successfully applied.
