boiler for supply heating hot water

Boiler flue gas at a dew point of about 55 ℃ (excess air coefficient 1.15), only the medium is heated to a temperature below 55 ℃ recovering heat of condensation in the flue gas heat recovery in order to achieve better results at 30 deg.] C or even less . In the field of the central heating, hot net return water temperature above 50 ℃, flue gas can not sufficiently recover the heat of condensation. This method of addition of the condensing heat exchanger directly in the tail gas boiler for supply heating hot water is often only partially recovering the latent heat of the flue gas, the heat of condensation can not be achieved depth recovery.

Horizontal coal-fired boiler for supply heating hot waters, the fuel burned on the grate, the flame through the low wall to the burning room, from the burning chamber by the two sides of the wing flue to the former smoke box, and then to the smoke chamber from the smoke pipe, and is drawn into the atmosphere through the chimney then by Induced draft fan, not only to prevent the bottom of the shell by the furnace high temperature radiation, but also the high temperature tube board inlet smoke temperature drop, combined with secondary water back, the bottom of the barrel without dead water, but also can effectively prevent Tube plate due to cold, boiling and scaling and the bottom of the convex package, the smoke turned to the smoke chamber can play a role in dust, but also reduces the original dust concentration.

Fast one side condensing steam boiler for supply heating hot water complete protection, safe and reliable, more than 10 kinds detector guard, round protection boiler safety; proprietary condenser can maximize thermal efficiency, low environmental discharge; Chinese full touch control interface, let operational status at a glance; the use of ND steel and steel and aluminum hybrid materials greatly extend the life of the boiler.

When the boiler for supply heating hot water capacity is calculated, in order to use 100 heads (maximum value) as standard, ignore how many people use, but to estimate the number of nozzles as a unit, as long as 100 nozzles can be used simultaneously.
