Title: Feed water preheater for water heater, water heater, and front cover thereof
Inventor: TOMINAGA NAOTO
IPC: F24H1/00
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a feed water preheater which can improve the thermal efficiency of a water heater by recovering the sensible heat and latent heat of the waste gas from the water heater when the preheater is attached to the water heater. SOLUTION: The feed water preheater 33 has a water pipe composed of a stainless steel pipe, and a heat exchanger 34 which belongs to the water pipe and is constituted of stainless steel fins, and the preheater 33 is connected to the exhaust port of the main body of the water heater. Water is supplied to the water pipe of the heat exchanger 34 and the feed water flowing through the water pipe is supplied to the main body of the water heater. The feed water supplied to the main body is preheated through the heat exchange between the waste gas discharged from the main body and the feed water in the water pipe. In this case, the heat exchange is preformed sufficiently and the temperature of the waste gas discharged from the preheater 33 becomes the dew point of the waste gas or lower. Therefore, the steam in the waste gas condenses and the latent heat of the waste gas is utilized for preheating the feed water. The condensed water is discharged from a drainage discharge port 35.

Title: Fuel characteristic detection device
Inventor: TAKAGAWA SATOYUKI
IPC: F02M37/00
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To appropriately correct a learning value of a fuel characteristic degree even in the case where a fuel characteristic is varied by adding a fuel to a fuel tank. SOLUTION: The former fuel Fold and present fuel Fnew are calculated in Steps 501-502. It is judged whether or not an oil feed is carried out based on a difference ΔF1 of the former fuel and the present fuel in Step 503. When it is judged that the oil feed is carried out, a fuel ratio Flvp of the former fuel and the present fuel is calculated in Step 505. A correction coefficient Kadf for correcting the learning value Lvad of a heavy fuel degree corresponding to the fuel ratio Flvp calculated is calculated in Step 506. The correction coefficient Kadf is multiplied to the learning value Lvadb before correction to determine a final learning value Lvad in Step 507. Thereby, above routine is completed.  Thereby, since the correction coefficient Kadf is calculated corresponding to a fuel ratio of the fuel added even if an oil feed is carried out, an appropriate correction of the learning value can be carried out.
