Abstract

Heating furnace which has been used by farmers to boil salt feed water is a traditional wood-fired furnance that is very simple and very inefficient. Researchers have made several modifications to the furnace unit multi-pot configuration that can utilize waste heat in order to improve the efficiency of the furnace. Potential waste heat of exhaust gas can be used as preheater. The methodology used to asses the performance on the furnace in water boiling test method operating condition of the cold start, hot start, and simmer. The data obtained then analyzed, the result showed that the burning rate and fire power that occurred during the cooking procces of the operation conditions of the cold start, hot start, and simmer increase, but the thermal efficiency decrease. This indicates that increasing of combustion efficiency has not been able to be utilized to the maximum heat. Value of the thermal efficiency of the furnace is affected by the value of useful energy to heat the water in the pot and the amount of energy entry/energy of combustion.

Abstract

Appliance of Heat Exchanger type 53 EA-1001 exist in company PT. Pupuk Iskandar Muda operate the time some long time is hence formed by coat of fouling, existence of fouling will lessen the hot coefesien transfer totally (U) to a point appliance planning reach the minimum price, this information is obtained to can to schedule for the periodic routine of sweeping as well as commutation of pipe of appliance of heat exchange which is improper used again by prediction is maximum gather  fouling at appliance of Heat Exchanger. Existence of fouling will lessen the final hot coeffesient transfer to a point planning, so that can be scheduled for by a routine treatment. Hot influence Coeffesient transfer totally ( U) to fluid flow speed, resulting height of stream speed. 8640 hour operate for at fouling factor 0,0082 (Rd) yield the volume fouling 0,0066 m3 need the treatment of age Heat Exchanger 27th year of gagging fouling at volume 63,585 m3. Stream emiting a stream is laminar with the value 950 Btu.ft3 / hr.lb.s energy and 1,46 times from missing energy in the situation without there is fouling.
