What is economizer in boiler?
Economizer is an accessory of boiler that recovers the waste heat from the flue gas blown out of the boiler. Thus it actually "economizes" the operational cost or in other words, improves the efficiency of fuel utilisation in the boiler. The temperature of the flue gases ( the mixture of burnt fuel & air ) depends up on the steam pressure ( temperature more precisely ). Higher the steam pressure generated, the higher is the flue gas temperature. Economizer is a heat exchanger which exchanges heat between water ( which is fed in to the boiler ) & the flue gas. It means it increases the temperature of the feed water using the otherwise wasted heat of the flue gas. So the water entering the boiler has higher temperature compared to the one without this economizer. This higher temperature of water requires less amount of heat to generate steam so the operation becomes "economical". Similarly the economizer can also work to heat up the air entering the boiler through the flue gas heat, instead of heating the water.
What is air tramp?
Tramp Air is air that leaks in through faulty gaskets on clean out covers, doors, between boiler sections and around burner mounting flanges. Air that infiltrates into the heating appliance other than designed by the manufacture can be classified as tramp air; that dilutes flue gas temperatures. The composition of the flue gases is also diluted by tramp air. This retards the technicians ability to accurately monitor and control combustion conditions. Tramp air results in reduced efficiency.
How high should a chimney stack be above the roofdoes the height include chimney pot?
Any chimney should terminate at least 600mm above the ridge height. This is a minimum to comply with building regs. This is measured to the top of the pot. If the terminal is coming out of the "slope" of the roof and not the ridge, then at least 2.3m measured horizontally from the roof surface. These are to meet the minimum requrement of building control but in reality can differ with each installation. Things like neighbouring buildings, tall trees and locallity can all affect the working of the chimney, as can the internal size of the flueway and where it is located on the house itself. If the chimney is internally built, there is good insulation from the building itself to keep the flue gasses warm. If the chimney is on a gable end with only 4" of brickwork between it and the outside, then the movement of the flue gases will be slower due to them cooilng down. I would like to say that you should be confident in the advice given by getting a tradesperson that has the relevant certificates to do the job in question. but you would be better contacting the governing body in question (HETAS or GASafe for example) and getting the list of recommended installers.

Who was Bull Durham tobacco?
= Bull Durham tobaccothe 'cheapest luxury' = by Delbert TrewExcerpts from the 1971 Bottles and Relics Magazine reveal the history of Bull Durham smoking tobacco selling for five cents a bag and billed as "The Cheapest Luxury In The World."The tobacco became famous after 1860 when the trademark was registered, as almost every posed photo of a man showed the small round paper tags hanging from a vest or shirt pocket. This product took center stage in the West just like Arbuckle Coffee and Stetson hats. After years of smoking pipes and chewing the old "rope and cable twists" of tobacco almost any change was revolutionary. When James R. Green of Durham Station, North Carolina began offering a finely chopped tobacco, flue-cured for quality and mildness, his customers jumped at the chance to try his new product.When he packaged the tobacco in a soft white muslin sack with draw-strings, all of which fit neatly into the average vest or shirt pocket it further enhanced the product. As cigarettes made their debut, Mr. Green added a small packed of cigarette papers to the bargain and the rest of the story is history.
