Burn boiler why to want to use salt and formula of boiler efficiency computation

On website product and keyword, will undertake explaining below, it is to be boiler product of this one important website, and it is to need to have comprehensive understanding and thorough knowledge, such ability are correct and reasonable the use effect that use this product and has had. In addition, will tell to all of us, also be beneficial and harmless, at least can increase him the professional knowledge of this respect.

1.Why to burn boiler to want to use salt?

Burn boiler to use salt, it is to undertake to water bate gets bate water. General, boiler contains impurity with the meeting in water, and it is hard water, will heat the word of boiler with this kind of water, boiler interior produces furring easily, and furring can affect caloric to conduct and increase the sources of energy to use up. And, furring still has to boiler tube wall corrode action certainly, still can expand because of overheat and rousing a bag to be out of shape is cartridge igniter even, bring undesirable consequence. So, salt is added to get bate water in wanting to use water in boiler, will avoid afore-mentioned these problems.

2.How is boiler efficiency calculated?

The thermal efficiency of boiler, its are to useηWill express, the consideration that and be has correspondence is formulary, it is to be: Boiler efficiency=Output quantity of heat / × of input quantity of heat 100% , and the formula that answers relatively with formula of this one computation, it is to have the following these, it is to be:

Boiler inputs × of quantity of specific fuel consumption to enter boiler fuel low heat output

The capacity of boiler of ＝ of quantity of heat that boiler outputs ×The capacity of boiler of ＝ of quantity of heat that boiler outputs ×Overheat vapour specific enthalpy - specific enthalpy of boiler water supplyOverheat vapour specific enthalpy - specific enthalpy of boiler water supply- boiler blowdown flow rate ×- boiler blowdown flow rate ×Specific enthalpy of boiler saturation steam - specific enthalpy of boiler water supplySpecific enthalpy of boiler saturation steam - specific enthalpy of boiler water supply--Boiler cold broken bits implement the specific enthalpy of cooling water backwater - cold broken bits implement the specific enthalpy of entrance cooling waterBoiler cold broken bits implement the specific enthalpy of cooling water backwater - cold broken bits implement the specific enthalpy of entrance cooling water× cold broken bits implement cooling water quantity

3.Low-pressure industry boilerUndertake water quality detects, are its specific be to detect what index? Is how distinguish through nameplate often press boiler or bear press boiler?

Low-pressure industry boilerUndertake water quality detects, its detect specificly index, it is to beWater supply hardness, Water supply chloric root, water supplyPH value, Content of water supply oxygen, Boiler water total alkalinity, Boiler waterPH value, Boiler water chloric root, Root of boiler water phosphoric acidAndBoiler water sulphurous acidThis nine, if this boiler ton it is to be in on number6 tons the following, so, can omitContent of water supply oxygenThis one parameter.

Passing nameplate to distinguish is often press boiler or bear press boiler, basically be to see nameplate go up whether mark has rated vapour pressure, if some words are to be bear press boiler, it is conversely to often press boiler. In addition, what everybody needs to know is, steam boiler is commonly bear press boiler, part of hot water boiler is to often press boiler.
