The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

• Phosphate Reaction: Ca 10 (OH) 2 (PO 4) 6 Hydroxyapatite [Adequate Alkalinity] • Magnesium Reactions: Mg 3 (PO 4) 2 Trimagnesium Phosphate [Low Alkalinity] • Magnesium Reaction: Mg(OH) 2 Magnesium Hydroxide [Adequate Alkalinity] Fuel Loss Due To Scale • The chart on the left shows the fuel loss in a boiler based on thickness of scale
Table 7-4 gives the TSP dosage fac-tor (ounces per gallon) for all values of alkalinity. The boiler volume is multiplied by the factor and the dosage of TSP is entered to the nearest one-half ounce in the appropriate space. The increase in phosphate due to TSP is given in the last column.
Will dosing a boiler with sodium phosphate affect the pH? Your original mixture with N a 2 H P O 4 / N a 3 P O 4 will have a much higher pH than simply using N a 2 P O 4 alone. The original solution will be buffered at a pH of around 12, whereas the new mixture will naturally form a buffer with water as N a H 2 P O 4 / N a 2 H P O 4 at a pH around but just above 7.
steam load, changing desired phosphate residuals, or holding the phosphate dosage constant. Examining the spreadsheets reveals that if the feedwater calcium level is low, most of the product dosage goes to provide residual in the boiler water. If the calcium level starts …
