THE NELSON GASWORKS.
VIEWS OF THK WESTI'UKX GAS ENGINEER, INTERVIEW WITH THE COUNCIL COMMITTEE. THE NEW PLANT PRAISED. At the rnvi tatton of the Mayor of Nelson (Mr H. Baigent), Mi* Bradley, Engineer to -the Westport Municipal Gasworks, met the Gaa Committer of the Council last I Friday evening. lie stated that ho 'was much impressed with the al-. terations and enlai*ft«*men;is of the ! pkmt at thi* Nelson Gasworks, aa now beiiiijg carried out by the City Surveyor, Mr Henderson. It was far more difficult to neconstropt than to build new works. The alterations were of a character that wih'-Ti complete would ,be a credit to the Council and the Engineer. The city would be in possession of up-Ur-date ami efficient works, and so far as he could see very cheap works. In regard to the new retort house, he failed to see how the new retorts could have been erecttod in the old house. Apart J from other difficulties, the comfort I of the stokers rwjuired consideration. As it was, the new retort house was of such dimensions that the comfort of the men had been studied. Provision had been allowed for the erection of drawing^ oha ruling, and coke conveying machinerv. aiyd also, space foi* storage of coah The retorts were up-to-date and oapnible of giving pvoitable results. Mr Bradley - said .he two empty owns should be fill•d in with retorts before next winWith reference to the tar extractors arid small discharge pipes, which are the cause of the thick tar trouble, Mr Bradley said these were not rolej'iiml, but as they were ordered by the late Surveyor Mr Henderson had ei\**ted them. There would be no difficulty, and only a slif>ht expense in taking these out, and substituting a simpler arrangement, that would cause no trouble with thick tar. The retorts wove capable of being worked at a high temperature. the heats in Mr Bradley's opinion bemg. if anything, too high. This sh'oweid that care and attention had been displayed in the erection of the retorts and generators. Mr Bradley, continuing, said tne foul main ami pipe condensors were so arranged that thc lieht tar travelled with the gas, condensation v-iati und'„<r control, ofnd took place slowly. By this means the napthalcne trouble couid be controlled, if not entirely done away with. The annular' condensors were of ample capacity, and could be duplicated when neqessary. Mr Henderson had designed this part of the plant on scientific lines to enable thc naptbnleive to L- removed along with the tar, during the condensation of the gas. The exhauster, washer, and scruljber were of ample capacity for a considerably krgor make mf gas than at present required. AU this plant had bve-pass connections, and could ' thrown off for cleaning without interfering with gas making. The purifiers and centre valve were up-to-date and of ample, capacitv for a works with a consumption of 100,000,000 feet a year. Mr Henderson h.ul wisely placed the purifiers in the old retori house. The pipes to tne .scrub".»>!r were 12-inch diameter, from scru'Jlx-r to holder 10-inch. The whoio of the plant and ar-ran'gjenic-ii't ha-d <INY?n well thought out" and carefully erecuod. Ia conclusion, Mr Bradley said there could be no doubt that owing to several circumstances the work had Hee.n difficult to carry out, while an efficient gas supply was lr>pt up at the same time. It was a wonder to him that more s-rious trouble had not taken place. The work would-be com-plivt-xl so.- Ua-r e<s the orp.ctipn of new;* plant. went in a few weeks. and. when complete, as he had -before stated, thev would bo a credit to the Council" and the En&'ineer. Mr lira dley gave information as to savings that could he elected when the alterations were completed, es-1-ojckilly by th- substitution of another process of purification for the lime now used, and also gav? his views oat the maivajoemcnt of ihe works and duties of a resident! foreman. , _ _ , The Commit tec thanked Mr Bradlev for the valuable -information t-ivf-r, and sai-d they were pleased to havi? such an encouraging report.
