Especially now inflation, such as water, coal and natural gas prices will only rise, and electricity prices will only be lower. Electric boiler products consume about 100 watts per square meter per hour. There are many responsible electric heating enterprises have a commitment, calculated according to 100 square meters of houses, from November 15 to March 15, a total of four months, the electricity bill does not exceed 2000 yuan. Ensure that the temperature is 18 to 22 degrees. If normal use exceeds local central heating.

Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard [1993] No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial steam boiler parameters Series" and GB3166-82 "movable coal fired hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."

Why supervisory inspection-free steam boiler steam boiler characteristics can exempt? According to the "Steam Boiler Safety Technology Supervisory Regulations" provides that the normal water level of boiler water volume less than 30L in the boiler does not belong to the scope of the surveillance. When the normal water level of boiler steam boiler water volume is only 27L, like installing a home water heater as safe. So steam boilers belong to exempt boilers. You can avoid the security of small steam boiler What are the benefits? 1, you can not build a separate boiler room, can be placed in the basement, roof and other places 2, do not have a full-time duty Boilermakers (conventional boiler requires certified fireman) 3, eliminating the need for a year dealing with government departments, burning more peace of mind coal steam boiler What are the advantages over conventional steam boiler?
