How To Operate Wood Burning Incinerators Under the Law

Orrie Hamilton has issued a special bulletin for the Southern California Retail Lumber Association on the subject of "approved standard operating procedures for wood burning incinerators," n'hich is packed with practical directions for burnirrg u'ood refuse in accordance with the law, so as to avciid smog and other air contamination.

He quotes The California Health & Safety Code rules, forbidding emission of dense smoke from an incinerator for more than 3 minutes in any one .hour, and also irnposes strict limitations on emission of particulate matter and of gases and fumes. Any person rvho violates the state larv or a rule or regulation of the Air Pollution Control District is guilty of a misdemeanor. This includes both the orn'ner and immediate operator of the incinerator.

A basic temperature of at least 1200 degrees Fahrenheit shoulcl be maintained. Incinerator should not be used until sufficier.rt $'aste material has been accumulated to l,varrant such use, rvhich may mean burning scrap or .lvaste material sorne time after starting up the plant, or it may mean burning it only or"r alternate days. Incinerators are designed for :r given cluantity of combustibles, and, should this cluantity varv greatly, either black, u'hite, or bro\\rn smoke will result.

Generally speaking black smoke means insufficient air in the incinerator, rvhile t'hite or brorvn smoke rne:rns too much air. Too much air r.vill cool dorvn the fire below recluired temperatures. Changed conditions in the plant should be follou'ed immediately by corresponding adjustments in the incinerator. Such changes usually mean adjusting the amount of air getting into the incinerator, or putting in additional scrap r,vood to increase the temperature. Never burn enough material at one time to cause the flames to reach the screen of the incinerator. It IS possible to burn such materials as oily rags and material containing paints and lacquers providing these items are burned in very small quantities and only when extremely high temperatures exist.

Keep the incinerator in good repair at all times, plugging all leaks in the blower system, plugging leaks at the point u'here the material enters the incinerator, maintain in good order the devices for regulating the air entry, insure the close fit of the charging door, clean out accumulated ash regularly, and keep the screen at the top always clean and whole. Close watch must be kept on the incinerator to insure good operation, as incinerators are not automatic machines.

Proper attention will facilitate the use of the incinerator with a minimum of difficultv. So says Mr. Hamilton.

HcU Million Homes Under Construction

Fully half a million homes r,vere under construction across the country as National Home Week opened on Sept. 10, according to C. B. Sweet, president of the National Retail Lumber Dealers Association.

"The number of new homes actually being built during the week rvill be the greatest ol all time as a result of the record-breaking number of housing starts during the spring and summer months," Mr. Sweet said.

"In larger communities, and in many smaller ones, the public rvill find a wide variety of new homes going up in every price class, with emphasis on lower-priced homes for lorv-income families.

"Despite the tightening of mortgage credit terms under the defense program, home building is expected to continue :rt a relatively high rate through the end of this year, with the result that families wanting or needing new homes will continue to find a good selection to choose from. National Horne Week is the ideal time to look around and inspecl the good values to be obtained in 1950's new homes.
