Description
Technical field
This utility model relates to hot-water heating system, the hot-water heating system required especially for hydraulic boiler set water.
Background technology
Boiler pressure parts must carry out the water pressure test after Non-Destructive Testing and heat treatment are qualified, and the water pressure test is in manufacture course of products
One important procedure, as halt quality control in addition.The general temperature of water pressure test water can not be the lowest, especially winter, closes
During gold Steel material hydraulic pressure, water temperature is less than the brittle transition temperature of steel grade, in fact it could happen that Materials Fracture.For exported product, perform U.S.
The product of state's mechanical engineer association ASME boilers and pressure vessel code requirement, " power boiler builds rule to ASME standard the I volume
PG-99 regulation in then ": " boiler in the finished, should carry out water temperature and is not less than ambient temperature and is under any circumstance not less than
The water pressure test of 70 °F (20 DEG C) ".The water consumption of boiler component hydraulic pressure is bigger, if bought, hot water cost is high, store difficulty.
Design this heater can in the winter time quickly, economical, effectively obtain hot water, it is ensured that the boiler pressure part water pressure test normal
Carry out, it is ensured that product quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of boiler feed water heater, and this device can ring in the winter time
Under border, quickly provide test water for hydraulic boiler set.
In order to solve above-mentioned technical problem, boiler feed water heater of the present utility model, including internal box, in described internal box
It is provided with three backhaul heating surface coil pipes, is provided with fast-burning furnace below described three backhaul heating surface coil pipes, also includes preheating water tank, in advance
Boiler is arranged on the roof of two adjacent sidewalls of internal box and internal box, and another adjacent wall of described internal box sets respectively
Being equipped with water tank and protective door, described three backhaul heating surface coil pipes connect preheating water tank and water tank respectively, also include smoke exhaust pipe,
Described smoke exhaust pipe is connected on internal box through preheating water tank.
In technique scheme, also include that gas baffle, described gas baffle are arranged on smoke exhaust pipe bottom, described gas baffle side
Being provided with through hole on wall, described through hole connects with smoke exhaust pipe.
In technique scheme, inside described protective door, it is provided with insulation material.
During use process, first inject water into preheating water tank, enter back into three backhaul heating surface coil pipes and quickly heated by fast-burning furnace,
Discharge can use finally by water tank.
Boiler feed water heater of the present utility model provides the benefit that: efficiently solve the boiler pressure part water pressure test in winter
Required a large amount of hot water, and quickly, economical, efficiently, equipment investment is few, floor space is little, simple and practical.
